If I could give 10 stars, I would!!! We have finished our summer program at Sunnyvale campus. We are absolutely lucky to have some amazing teachers who care and inspired my kid! Especially Miss Sunita and Miss Stacy who are truly one of a kind. They are the reason my daughter woke up every morning excited to go to school. Their warmth, patience, and ability to connect with each child are beyond words. Miss Sunita is always smiling and cheerful. Miss Stacy is always playing with full energy with the kids. They created a space where kids feel safe and seen. Every little effort is noticed, every day we were told about the highlight of my kid. As a parent, it's rare to come across someone who not only teaches but inspires. We are endlessly grateful -- this summer has been unforgettable at Challenger Sunnyvale . THANK YOU all from the bottom of our hearts!

It was my first time to sign my kid up for a Challenger summer camp as he was a little behind on phonics and reading in his play based school. And I have to say that the summer camp at Challenger School exceeded my expectations! The program is a great balance between academic rigor and summer fun. My 6 year old son excited to go every day and came home eager to share everything he learned about. He also loves the science and art session a lot and would not go home until he finishes his project every day. I want to especially share my thanks to the head teacher Dhruva Tamboli in Kindergaten Class, who played a key role in my son's major progress during the 7 weeks. Her encouragement and patience and dedication not only improve key academic skills but also boosted my son's confidence and love for learning. At the end of the program, my son took the assessment and proudly passed it and he will become a happy first grader in Challenger soon.

Our daughter attended the pre-K program at Challenger School Sunnyvale last school year with Ms. Ann, Ms. Swati, and Ms. Shilpi. When she joined in the spring, she was a bit behind in phonics and spelling, but the teachers supported her with incredible patience and care. She quickly caught up academically and grew more independent and organized. Most importantly, she genuinely enjoyed going to school every day! She loved all her teachers--even those from the other pre-K class--and eagerly shared stories about her day. We feel truly fortunate to have had such dedicated teachers during this important early stage of her education.

We joined this campus in 2021, and I noticed that the negative reviews were from several years ago. The school changed its principal a few years back, and I am currently very satisfied with its operation. The school's director is very responsible, and the teachers are all very nice and have a strong sense of responsibility in guiding my child. The environment is clean, the campus is spacious, and academically, it consistently maintains corporate uniform standards, which I appreciate. My child is slow to warm up, and every day when I pick her up after school, she wants to play a bit more and doesn't want to leave. For me, that's enough. Overall, I am very happy with this campus

Nothing but great things to say about this school. Staff and teachers are great. My son and daughter both enjoyed their classes very much and boy did they learn a lot! The office staff were really helpful and attentive as well. Highly recommend to start your kids young here. They can actually learn a lot and the teachers/curriculum can really bring out the best in them and reveal their true academic potential! Only downfall is of course the tuition but if you can afford it, I'd say it's worth it.
