  Our daughter has been going to Challenger Palo Alto for two years and she had a fine experience. We signed her up to Challenger Sunnyvale for summer but she had such a bad experience that she would cry every morning begging not to go to school. So we ended up not going through the whole summer.

  Our son just finished 5th grade, and we are sad to leave (Decided to transfer to a school with high school, so avoid switching school for middle->high). We really wished Challeger could have its own high school. We joined during the pandemic (Kindergarten), and even then, the video lessons and live teacher interaction were excellent. Here is why this school is so special for us: Experienced Teachers: Every teacher we had was a veteran who had taught in Sunnyvale for many years. They didn't just teach facts; they shared life experiences and practical wisdom, which we really appreciated. Great Leadership: The Director keeps everything running smoothly. Academics, scheduling, and activities are always organized perfectly, creating a stress-free environment for parents. Strong Relationships: The bond between teachers and students is wonderful, and the kids form genuine friendships. It’s a respectful, caring community, not a cold pressure-cooker. Excellent Staff: The office and support staff are both incredibly efficient and genuinely warm. They answer emails quickly, solve problems fast, and always greet you with a smile. We started on Zoom and are leaving with a happy 5th grader who found his place and felt safe to grow. Highly recommend!

  We’ve had a very positive experience at Challenger School Sunnyvale. My daughter joined the preschool program when she was just over 2 years and 10 months old. At that time, she could not speak English at all. Before she started, I only had the Challenger command list and taught her a few simple phrases like “stand up” and “sit down.” In less than six months, she surprised me with how much English she had picked up. She came home with so many new words, sounds, and expressions, and it has been amazing to watch her language grow so quickly. We are especially grateful to her teachers, Ms. Sunitha, Ms. Lale, and Ms. Shilpi. They are kind, patient, and caring, and they have helped my daughter feel happy and secure at school. During spring break, I placed her in a different daycare, and she told me she was happy to go back to Challenger afterward. That really showed me how comfortable and attached she feels there. I especially want to praise Ms. Sunitha. She always keeps me informed about my daughter’s day—what she said, what she did, and how she interacted with others. She shares sweet details that help me understand my child better. She also tells me when my daughter helps clean up toys and helps other children know where their things belong. Ms. Sunitha is truly a wonderful teacher and a very kind person. We are very happy with our experience at Challenger Sunnyvale and thankful for the care and support our daughter has received here.

  My child has been attending this school since February 2026, and he tells me every day how much fun he is having. He is gaining wonderful experiences here on a daily basis. He comes home each day with things he has created through learning activities, crafts, and drawing, and I truly enjoy seeing his work every day as a parent. He absolutely loves his teachers, Shilpi and Sunitha, and I can clearly see how sincerely and thoughtfully they support him, especially since his English skills are still developing. This is a wonderful school, and as a parent, I feel it is a place I can trust with confidence.

  Our experience with Challenger School (Sunnyvale campus) has been deeply disappointing. While the school emphasizes academic rigor, our recent experience raised serious concerns about how student safety, behavioral incidents, and exceptional family situations are handled. There were repeated concerns involving inappropriate behavior toward our child that were known to staff. However, the response remained limited to warnings, without a structured or proactive resolution. This lack of escalation or preventive action was concerning. The situation became even more troubling during a genuine family emergency that required our child to be with us. The school’s approach lacked empathy and flexibility, and decisions felt rigid and disconnected from the realities families sometimes face. Additionally, decisions following the incident were made with limited transparency and without meaningful parent involvement. The overall process felt unilateral, with little opportunity for discussion or consideration of context. As a result, we withdrew our son from Challenger School with immediate effect due to concerns about accountability and unilateral decision-making by the school management. We urge other parents to monitor their children’s well-being closely, as these issues may not be apparent in day-to-day school life. Awareness and proactive communication can help avoid situations like ours. We hope the school reflects on this experience and improves its processes around bullying prevention, incident handling, compassionate handling of family emergencies, and parent communication.
