My 3-year-old son started Challenger Preschool with almost no English and significant separation anxiety. He is also a highly sensitive child, so I was honestly very worried. I had heard that Challenger was a very structured school, and I wasn't sure if he would be able to adjust. To my surprise, everything went much better than I ever expected. By his third day, he walked into school without crying and even took naps there. That was something I never imagined would happen so quickly. Over the past six weeks, he has come home happy every single day. He is always excited to show us the artwork, drawings, and classroom projects he made. It's obvious that he enjoys his time at school and feels proud of what he accomplishes. The biggest surprise has been his English. Before starting school, he couldn't speak any English at all. I wasn't expecting a three-year-old to make so much progress in such a short time, but now he comes home pointing out letters, telling me their sounds, and sharing words that start with different letters. Watching his excitement about learning has been incredible. I also want to mention that the teachers (Miss Sonali and Miss Hema) are much warmer and more caring than I had expected. Although Challenger has a reputation for being strict, our experience has been that the teachers are patient, gentle, and attentive to the children's emotions while still maintaining a well-structured classroom. On the days I picked him up early, I saw happy children engaged in activities, and the classroom had such a positive and joyful atmosphere. A special thank you to Miss Sonali and Miss Hema. Your kindness, patience, encouragement, and dedication helped my son feel safe, loved, and excited to learn. As first-time parents sending our child to an English-speaking preschool, we were naturally anxious, but you made this transition so much easier than we could have imagined. We are truly grateful to have had such a wonderful preschool experience. I would highly recommend Challenger to any family, especially those who are worried about sending a child who doesn't speak English. Children are often much more capable than we realize, especially when they have caring teachers like these. read more

The best decision we have made for our son's early education by enrolling him at Challenger bareyessa for preschool. Ms Priti and Ms Prerna have been wonderful teachers to my son. In just a few months he has made such an amazing progress in phonic, reading, spelling and writing and most importantly he loves learning. He absolutely loves being in their class and has already decided that his little sister should have them as teacher as well :) thank you for making his preschool experience so special. read more

We've had such a great experience with Challenger Berryessa! Josh attended this school from the time he was about 3.5 years old, and unfortunately we had to discontinue last year after we moved. This summer, he came back for their summer program, and he absolutely loves being back! He really enjoys all the activities and learning, and comes home happy and excited to tell us about his day. A special shout-out to Ms. Preethi and Ms. Prerana -- Josh loves both of them, and we really appreciate how caring and wonderful they are with the kids. It's been so nice to see Josh back at Challenger Berryessa and enjoying his time there again. We have a lot of good memories from this school and are very happy with his summer experience! read more

Started sending my 3 yr old boy to the 1.5 month summer pre-school to get ready for the Aug pre-school as we stayed really close in the Berryessa area. There had been a lot of feedbacks and playground talks among parents that Challenger had a very strict culture and tough curriculum that not every kid can handle and adapt. The feedback is that usually boys that have high energy and too active will get into trouble a lot. To our surprise, he loves the school just after 1 week and always looking forward to going to school in the morning, we also see a big difference in his English speaking ability and his independence in behavior. We are assured to let him continue with this school for the next coming years. We want to give special thanks to the 2 teachers Miss Hemanth and Miss Sonali for their loving care and coaching, we can tell he is very happy with them and there is the strong teachers-students chemistry we observed. Kids usually are very pure and express directly what they feel so we are very assured when he nods and say he likes his teachers and wants to go to school. From what I see so far, I believe Challenger has a very strong track records and is well managed across all their schools to groom the students to be academically strong and independent character especially needed in the competitive Bay Area. No wonder Challenger had been listed as one of the top private schools in US. read more

We are very happy with this school and truly appreciate all the teachers' hard work and care. A special thank you to Ms. Prerana and Ms. Preeti for doing such a wonderful job teaching my child. They are patient, caring, and supportive teachers who helped my child learn and grow a lot. Not only did my child improve academically, but he also learned how to be disciplined, respectful, and responsible. The teachers created a positive and encouraging environment where he felt happy and confident every day. My child had a great time at school and always enjoyed going to class. We are grateful for the love, guidance, and dedication from the teachers and staff. Thank you for making such a positive impact on my child's learning journey. read more

We feel incredibly lucky to have had Miss Preeti and Miss Prerana as our child's preschool teachers. They are both patient, caring, and truly passionate about working with children. From day one, they created a warm and welcoming environment that helped our child feel safe, confident, and excited to learn. We've seen so much growth -- not just academically, but also socially and emotionally. Miss Preeti and Miss Prerana always communicate thoughtfully with parents and clearly put so much effort into every activity and lesson. It's obvious how much they genuinely care about each child. Thank you both for all the love, encouragement, and positivity you bring every day. Any family would be lucky to have teachers like you! read more

With the school year coming to an end, we wanted to join some of the parents below in sharing a few candid thoughts on our first experience at Challenger. Before finding Challenger, we went through a bit of trial and error, including 8 months at Bright Horizon and 2 other daycares that we left for various reasons. Looking back, we are just so glad we put in the effort to potty-train our son early so he could enroll here. Without a doubt, the school has been the most positive and impactful experience we have had to date. Our son joined Challenger at 2 years and 10 months old in August 2025, and he has truly benefited from the program in every way possible. He is a very typical boy: curious, energetic, sometimes focused, and most of the time not very focused at all... However, his teachers, Ms. Shivani and Ms. Sonali, consistently meet him where he is each day. They have even provided extra review sessions before and after class to help him along--something we did not discover until recently, which truly reflects their genuine dedication. Through their incredible care, our son successfully transitioned from those early, chaotic days to now confidently following directions, counting past 50, reading simple sentences, and even tackling basic math and more. But beyond these academic achievements, their guidance has supercharged his emotional maturity as well, completely changing our perspective on what 3 year olds are capable of achieving in the right environment. As parents, being able to witness this growth firsthand during the quarterly mini-concerts has been an incredibly memorable experience--it is truly jaw-dropping to see how much these tiny humans can actually do. Thanks to this structured environment, our son has also become significantly more confident, which has beautifully translated into his mood and behavior at home. He has made incredible strides in managing his emotions and self-regulating. In fact, our home routine has completely transformed; daily struggles around mealtimes, sitting still, and nap schedules have become seamless. Because he now thrives on a consistent schedule, his days are balanced with on-time meals and naps, giving him fewer reasons to be fussy. Which brings us to the elephant in the room that many parents ask us about: the rigorous academic schedule and the perception that the teachers are "too strict" for young children. From our experience, our son is neither stressed nor afraid of school. He genuinely loves going every day because he knows he is supported and cared for. While the program is clearly accelerated, we have watched his confidence, independence, and social skills skyrocket alongside his academics. It turns out that learning more did not weigh him down or "stress him" out... it actually gave him the drive and the tools to feel included and engaged with his friends, and even more connected with us at home. So while the school might appear strict at first glance, in reality, this has been the most caring, observant, and development-focused environment we have ever experienced. The maturity, confidence, and growth we see in our son every single day truly speak for themselves. A sincere thank you to Ms. Shivani and Ms. Sonali for your enduring patience and love; we feel so fortunate that you were both William's first teachers at Challenger. We also want to extend our sincere thanks to Ms. Anna and Ms. Tina for their steady leadership and support behind the scenes. Finally, thank you to the office team for always being so prompt, communicative, and helpful, which truly makes life less stressful for working parents. Last but not least a special shout-out to the morning drop off parents and staff that manage the drop-offs with the efficiency of an F1 pit crew. It truly feels like a village working together every morning. Hope you made it to the end of this review, and really hope some of our experience motivates you enough to start potty training your toddler if you haven't already and send them to Challenger preschool! read more

My daughter had a great time at challenger preschool class with Miss Shivani and Miss Sonali. Starting at the 3s class when she was 3.5 years old, she was not comfortable with her English. when the academic year ended, she can confidently speak in English, count to 100, knows a lot of stuff, can read three letter words etc. More than academics she loves being there and loves her teachers and friends. The teachers are also very caring and supportive. Thanks for a wonderful year. read more

Our experience with Challenger's Pre-K program has been amazing. In just one short year, our daughter has grown academically, built strong friendships, and blossomed into a confident young learner. Challenger has a reputation for a fast-paced curriculum, but our daughter has thrived on the challenge. This is largely thanks to the nurturing, structured environment created by Ms. Preeti and Ms. Prerana. They teach the children great habits, instill a sense of care for one another, and ensure everyone feels safe. It's clear they truly care about all of the kids. As parents, we love how patient and warm the teachers are. They regularly keep open communication during pick-up, making it easy to understand exactly how our child is progressing. On top of the academics, we have really enjoyed watching the kids sing and perform in the winter and spring showcases. It's been great seeing all of their confidence grow throughout the year. Challenger might not be for everyone, but it has been the perfect fit for our family so far. We highly recommend their pre-k program to any parent seeking the ideal balance of high academic standards and nurturing environment. read more

We cannot say enough good things about Miss Preeti and Miss Prerana in the D5 Pre-K class at Challenger School Berryessa! From day one, they have created an environment where our daughter genuinely thrives. Every single morning, she is incredibly happy and eager to head to school. What we love most is her enthusiasm when she gets home; she is always bursting with excitement to show us the academic work she completed and tell us all about what she learned. The academic strides she has made this year are remarkable, and it's entirely due to the perfect blend of structure and encouragement these teachers provide. We are so grateful for their dedication! read more

We are very grateful to Miss Preeti and Miss Prerana for all their kindness, care, and support in the D5 Pre-K class at Challenger School Berryessa. They created a warm and positive learning environment where our daughter felt happy, comfortable, and excited to learn every day. We saw a huge improvement in our daughter throughout this school year, both academically and socially. She learned so much and gained a lot of confidence.

Great school with an excellent environment. Our 2nd grader and preschooler look forward to school every morning. Thanks to the structured curriculum, we have noticed clear improvements in their development. The teaching staff is kind and truly invested in the kids. A special thank you to Ms. Sonali and Ms. Shivani in preschool class A2 and Ms. Joseph in 2nd grade. Both children have developed a great interest in learning here. read more

Miss Shivani and Miss Sonali are seriously the best, and you can just tell how much they truly love and care about the kids in their class. As a dad, it's such a relief to know my child is in a place where they feel totally at home and supported. I'm always super impressed with how they keep us in the loop--they give us great updates on everything from new things being learned to how behavior is being handled with a ton of patience. It's been awesome seeing the academic progress and watching that confidence grow, all thanks to the positive vibes they bring every day. We feel so lucky to have them looking out for our little one! read more

Our daughter is flourishing in Miss Cici and Miss Prerana's D6 Pre-K class at Challenger School, and three things truly stand out: 1 Whole-child care - Both teachers attend to far more than academics, gently coaching daily habits such as polite greetings, tidying materials, and even how to line up after recess. Their warm reminders and small celebrations have helped those good habits stick naturally. 2 Exceptionally close, face-to-face communication - All updates happen in person. At every drop-off and pick-up the teachers proactively share the day's highlights and any areas for improvement; when something important arises, they simply set aside time to talk with us on the spot. This real-time, eye-to-eye partnership lets us exchange observations and set shared goals without delay. 3 Tangible growth and happy friendships - In just a few months she has leapt from letter sounds to reading short sentences, confidently uses sequencing phrases like "first... then...," and even reminds us at home to "share and push in chairs." She has also formed her first close friend group, turning each morning drop-off into an excited dash into class. D6 has given her a structured yet joyful springboard at the most critical stage of early language development. If you're looking for a classroom that blends rigorous learning, habit-building, and genuine teacher-parent collaboration, D6 with Miss Cici and Miss Prerana comes highly recommended. read more

Challenger School - Berryessa - Elementary Schools Near Me - San Jose, California

I highly recommend Miss Preeti and Miss Prerana for the D5 preschool program. Our son was four when he joined Pre-K, and at the time he was reluctant to speak English and had no experience in a large classroom setting. After just one year, he has become much more confident and has made great progress in reading, writing, and drawing. I especially appreciate the weekly "show and tell" sessions, which helped him develop his public speaking skills. Overall, we are very satisfied with the school and truly grateful for the excellent guidance and support provided by both teachers. read more

Ms. Shivani has been an outstanding teacher for my child at Challenger. She genuinely cares about her students, helps shape their character and values, and provides timely, constructive feedback to parents. Her dedication, patience, and positive influence have made a meaningful impact on our child's growth and learning. We are very grateful for everything she does! read more

My son has been attending Challenger Berryessa for two years now -- he started in Preschool and is currently finishing up the TK program, with Kindergarten on the horizon. From the beginning, our experience has been nothing short of exceptional. Like many parents, I was initially concerned about the school's reputation for being "too academic." I worried it might come at the cost of creativity or social development -- that kids would turn into little robots. But that hasn't been our experience at all. The program is fast-paced and academically strong, yes, but it's also incredibly well-rounded. My son is thriving -- not only is he soaking up knowledge at an unbelievable rate, but he's also growing socially, emotionally, and confidently. I've been to more birthday parties this year than ever -- the kids genuinely get along and enjoy each other's company. His TK year has been another leap forward thanks to his incredible teachers, Ms. Saroja and Ms. Deepthi. They've continued to challenge him academically while supporting his emotional and social development. Under their guidance, he's become more independent, curious, and expressive -- and he comes home every day excited to share what he's learned. Their dedication and attentiveness to each student have made a lasting impact. Huge credit also goes to the incredible preschool team. Ms. Sarah and Ms. Khushali set the tone early in his preschool year with a perfect mix of warmth, structure, and professionalism. That standard has continued into TK and beyond. My son is now doing things academically that I didn't even touch until well into elementary school. It's exciting (and a little humbling!) to watch. The front office staff and Headmaster Mrs. Nguyen deserve their own praise. They're approachable, kind, and visible to the kids. My son talks about how they stop into the classrooms regularly -- it makes a big difference when the administration is familiar and friendly, not this mysterious group tucked away behind closed doors. There's no question that Challenger asks a lot -- of the students and the parents -- but the results speak for themselves. Teachers keep lines of communication open and give great insight into how we can support our kids' learning at home. It's a true partnership, and I genuinely feel like I'm giving my son the best foundation possible. If you're on the fence or uncertain based on rumors, I'd strongly recommend visiting the school and seeing it for yourself. Challenger Berryessa has exceeded our expectations, and I'm confident it will continue to do so as our son enters Kindergarten next year. read more

We visited this school for a scheduled interview/open house with our toddler. While waiting, our child briefly stood on a chair to look around. A staff member told him firmly that standing on chairs was not appropriate, which we understand as a safety rule. However, shortly after we were seated for the interview, the same staff member stated that she had "already seen what she needed to see," implying that our child was not a fit, before any meaningful interaction or observation took place. During the short interview, our child asked for water, and we were questioned on whether he could sit calmly without being given his bottle, which felt more evaluative than supportive for a child of this age. The experience felt rushed and somewhat dismissive, with limited opportunity for the child to warm up or for parents to ask questions. Families whose children need time to adjust to new environments or who value a more child-centered, developmentally sensitive approach may want to keep this in mind when visiting. read more

We had a great preschool experience at Challenger Berryessa. We started in the Threes class and continued into the Fours, and our child truly loved the school.Ms. Sarah and Ms. Khushali, the teachers for the Threes class, did an excellent job helping our son transition smoothly from daycare to preschool. Their warmth and patience made the classroom a welcoming environment, and their efforts helped the kids feel comfortable and excited to go to school every day. Our son felt so at home in their class that he didn't want to move on! Thankfully, the transition to the Fours was just as smooth, thanks to Ms. Preeti. She made the change easy and enjoyable for both the kids and parents. The care and effort she put into organizing events like Halloween and the Spring Program were truly commendable. Beyond the special events, the weekly classroom activities helped spark our son's interest in reading, coloring, and many other creative and learning experiences. Ms. Preeti's loving and nurturing nature made her a favorite among the children in no time. As the academic year came to an end, most of the kids were excited for kindergarten--but they were also sad to leave behind their beloved teacher. We're incredibly grateful to all the wonderful teachers at Challenger Berryessa, especially Ms. Preeti, Ms. Sarah, and Ms. Khushali, for the strong foundation they've given our child. read more

Exceptional Foundation for Learning and Growth at Challenger School -Berryessa Campus! We feel incredibly grateful to be part of the Challenger School community. It's not just a school -- it's a place where our children are nurtured, challenged, and celebrated every single day. Our younger daughter is in Pre-K with Ms. Prerna and Ms. Cici, and they've truly been a gift. Their warmth, patience, and structure have helped our daughter become more confident, independent, and excited to learn. She genuinely looks forward to school every day -- and that kind of joy speaks volumes. Her journey began in the Preschool (age 3) class with Ms. Khushali and Ms. Sarah, who made the transition into school so gentle and loving. Their encouragement created a strong emotional foundation and sparked a love for learning early on. Our older daughter has also flourished at Challenger. Ms. Nikolas (1st Grade) brought a fun, thoughtful energy to the classroom, building a solid academic foundation with so much care. Now in 2nd Grade with Mr. Arthur, she's grown into a curious, articulate, and motivated learner. His ability to inspire and empower each child is truly special. We're also thankful for Ms. Avalos, the Elementary Program Director, whose leadership radiates positivity. She treats every child with equal care and respect, and consistently encourages all students to grow and shine. Her presence sets a warm, inclusive tone across the school. One thing we really appreciate is the strong communication between teachers and parents. At drop-off and pick-up, the teachers consistently share the day's highlights and any areas for improvement -- all in person, face to face. That open and proactive communication makes us feel included and supported. Challenger also hosts seasonal programs like the Spring and Winter performances, where students shine on stage. These experiences have given our daughters such a boost in confidence and joy -- watching them perform is truly heartwarming. The classroom environment strikes a perfect balance of academics, fun, and creativity, always filled with positivity. It's a place where children learn, laugh, express themselves, and feel proud of their accomplishments. We couldn't be more thankful to the incredible teachers and staff at Challenger. They don't just educate -- they care deeply, inspire constantly, and believe in every child. Our daughters are thriving, and as parents, that's the greatest gift we could ask for. We couldn't be more thankful. read more

A Wonderful Foundation at Challenger School - Berryessa Challenger is truly an incredible place for young hearts to learn, grow, and be nurtured. My daughter has been part of the 3s and 4s Preschool program, and the growth we've seen in just two years has been nothing short of amazing. Last year, Ms. Sarah and Ms. Khushali were everything we could have hoped for in teachers--warm, attentive, and deeply committed. This year, Ms. Preeti has gone above and beyond to continue guiding my daughter's learning journey. We are so grateful for their dedication. As a working parent, I have limited time to focus on my daughter's academics. That's why I truly appreciate how well the Challenger curriculum and teachers support our family. In just two years, my daughter has gone from learning letters to reading full sentences and now enjoys age-appropriate books with confidence. It's been remarkable to watch her progress. Beyond academics, the emotional and behavioral support the teachers provide is equally important and deeply appreciated. They create a nurturing environment where children feel seen, supported, and encouraged to grow in every way. While we're not sure what the future grades feel like, we're taking it one step at a time. For now, we are simply grateful for the incredible start Challenger has given our daughter and how much she has thrived here. A huge shout-out to Ms. Sarah, Ms. Khushali, and Ms. Preeti--thank you for being such an important part of my daughter's journey. You are truly amazing, and we are so thankful for everything you do. read more

Our daughters have been going to Challenger Pre-school and school since they were in PRE-K. The growth that they have shown with reading, identifying numbers and words, being able to spell words and confidence build is amazing. The kids love their teachers and my wife and I also love interacting with them. The Front office staff is great as well. My 4 year old can read chapter books already and we never taught her anything at home and she surprises us by reading words as big as 'embarrassment' which is mind boggling. The school has a great running track and playground area. The classrooms are neat and teachers also instill cleanliness and obedience. One drawback that I have seen with Challenger is they don't cover Spanish language which is something I really want my kids to learn. Overall though it is a great experience and we highly recommend this school. read more

From the very first day my son stepped into the cheerful and welcoming environment of Challenger School, I knew we had made the right decision. But what truly made this experience exceptional was Ms. Preeti, his Pre-K teacher in D8. Her warmth, patience, and unwavering dedication have left an incredible mark on our hearts--and on our son's development. Thank you, Challenger School, for creating such a nurturing environment. And thank you, Ms. Preeti, for being the guiding light in our son's early learning journey. We are forever grateful. read more

We could see our child made good progress on Phonics, Reading, Writing, and Math skills. We're excited for the upcoming years and can't wait to start Kindergarten at Challenger School. read more

There's a lot of misconceptions and bias when people hear the name Challenger. Many assume it's "too academic," often based on secondhand information from those who have never even stepped foot on campus or enrolled their children in the program. We heard many of these same comments when we first considered Challenger for our son. Feedback like, "They don't let kids have fun," or "It's just all about academics," was a common phrase we would hear from other parents. Thankfully, my husband and I didn't let those comments deter us from scheduling a tour, and we're so grateful we didn't. We enrolled our son in the 3's program, and looking back, it was one of the best decisions we've made. His experience in that first year laid a strong foundation for his growth and continued success. A heartfelt thank you to Ms. Sarah and Ms. Khushali, they were instrumental in helping our son thrive. We never imagined that at just 3 years old, he would be confidently reading books with 3-5 letter words, writing his name legibly, and performing in front of a room full of parents with ease. Their encouragement, structure, and warmth truly made all the difference. In the 4's program/TK, our son continued to flourish under the care of Ms. Saroja and Ms. Deepthi. Not only did he further advance academically, reading at a level where he can order meals at restaurants independently and doing basic mental math, but he also grew emotionally and socially. He learned to manage his emotions and expresses himself creatively through art and storytelling. What continues to impress us is the level of personalized attention he receives, even in classes with 20-25 students. His teachers truly see and support each child as an individual. I know with their guidance; our son will be successful when he enters kindergarten. Another standout feature of Challenger Berryessa is the culture of warmth and care among the entire staff. It's amazing how every team member, from front office to teachers, knows the names of all the students and greets them warmly at drop-off and pick-up. That kind of environment doesn't just happen by accident; it's built by people who truly care. Yes, Challenger is academically rigorous, and that's exactly what we were looking for. But it's also so much more than that. The structure, the values, the care, and the consistency all contribute to a well-rounded and confident child. Parents who choose Challenger should be prepared to support their child's journey, but that partnership with the school is instrumental to your child success. No school is perfect. But we strongly encourage prospective parents to visit Challenger for themselves. Speak with the staff, observe a classroom, and see the curriculum in action. Don't let rumors keep you from discovering a place that might be the perfect fit for your child, like it was for ours. read more

My kid studied at Challenger School at Berryessa in the pre-K D4 class. We had a good year there and plan to continue the Kindergarten there. There are two teachers Ms Jyoti and Ms Shivani in D4 class and they are very good teachers. They are kind and patient. My kid loved the teachers and when leaving the school everyday, he would always hug the teacher. And my kid really learned things. At the beginning I had concern that whether those phonics, reading, spelling and number calculation and so on were too much for a preschooler, but actually they really had a good way to teach kids. My kid learnt it in a happy way. Besides academic, I could see his progress in social skill including emotional control. In general, we are satisfied with our choice to have the kid study there. read more

Lets be real here. Most people would only write a review if something BAD happened. So I'm gonna write a completely honest review. Hi! I'm a student at Challenger School - Berryessa, and let me just say -- if school was a video game, Challenger is the Hard Mode setting. Seriously, I've been here a few years, and I can now write essays, do mental math like a calculator, and answer questions faster than my parents can say "slow down!" The good stuff? The teachers really teach. Like, they mean business. We learn a ton, and we're kind of unstoppable in spelling bees and math contests. There's a ton of structure, which is great if you like knowing exactly what to do, how to do it, and when to do it (down to the minute). But... here's the thing. Every year, it's like we go through a secret level of "Student Survivor." Some of my classmates mysteriously vanish -- like poof -- gone by the next school year. It's not because of monsters or aliens (I think), but because the pressure is real. There's this "funnel" where only the top students move ahead like it's the finals of a science Olympics. So yeah, if you're not a fan of competition, you might feel like a background character in a math movie. The office staff? Very serious. Super organized. But sometimes they talk to you like you're there to check in for a dentist appointment instead of asking for a Band-Aid. A smile wouldn't hurt! Overall, I've learned a LOT at Challenger -- like college-level thinking in elementary school. It's just that sometimes, I wish there was a little more room to breathe... or doodle... or, I don't know, be a kid for five minutes? Still, if you love learning, challenges, and can handle a bit of pressure (and maybe the occasional classmate vanishing into thin air), Challenger is a total brain bootcamp. Just keep your backpack light -- your mind's gonna do the heavy lifting. So, Challenger is kinda Challenging (OBVI), but I enjoy it and you should send your kit here for sure! ~Local Challenger 6th Grader read more

Excellent, tried and true curriculum, so we are very happy with our child's learning progress. However, the school is terrible administratively: 1) Ms Anna, while she knows the curriculum inside out, is extremely rude and her tone is inappropriate even towards parents (not just children), 2) the school has poor and manual processes because it does not leverage technology, 3) children are in a black box within the school day because there is no app to help communicate and highlight our kids and what activities they've engaged in for the day, 4) poor communications (not frequently enough and not timely) to parents, 5) administration does not allow for bi-directional communications between parents and teachers. read more

Words cannot express how much I appreciate the whole school and teacher. My son has been studying at Challenger since Kindergarten. I have seen many negative reviews, so I decide to write a real reviews. First of all, Challenger is not for all the child, but for me it fits well for a hard working children. For many of parents who I meet in the challenger, we like to talk about the school system between challenger and other school. we all think that Challenger is a good quality education for parents who really want to invests their children in the best educational ,which provides support for the curriculum and instructional process. Next, I truly appreciate the whole school help my son to establish a high stand for himself, and keep wanting to improve his math and English skills. Elementary school is the first phase of a child's formal education, and the Challenger school help a lot of my son's first milestone set to build a strong good academic fundation. read more

This has been the first time that my daughter comes to Challenger, the K-prep level teacher Miss Sonali is very professional and patient. During the 7-week summer school, my daughter's writing has been improved a lot. I really appreciate Miss Sonali's guidance, and look forward to starting the kindergarten soon. read more
