8/10GreatSchools RatingParent Rating AverageWhittier International Elementary School has been an incredible experience for our family. We truly appreciate the school’s diversity and strong emphasis on cultural awareness, which creates an inclusive and enriching environment for students. The IB program’s inquiry-based approach encourages curiosity and helps develop lifelong learners. Every teacher and staff member is outstanding—dedicated, supportive, and exactly the kind of people you want guiding your children. We’ve also been very impressed with the school’s quick academic intervention when needed and the overall welcoming, supportive community. We couldn’t be happier with our experience here.Parent Review1mo ago
