10/10GreatSchools RatingParent Rating AverageTerrible experience here. Constantly made fun of and picked on by students and teachers treated me like a total idiot. Went from being respected by peers and teachers at my old school to ridiculed and laughed at by the entire class.Other Review5mo ago - Centennial Middle School

7/10GreatSchools RatingParent Rating AverageAs a parent, you hope for a school that sees your child, truly sees them, and helps them grow into the person they’re meant to be. Centennial doesn’t just meet that hope; it exceeds every expectation. My worries over this phase of life for my child have been replaced with joy.My daughter is thriving here in a way I never expected. From the numerous clubs that help explore talents and make new friends to dedicated teachers nurturing her talents and spark for learning. She’s discovering passions she didn’t know she had. These aren’t just activities to her anymore; they’re pieces of who she is becoming. The environment at Centennial is warm, safe and genuinely caring. My daughter says it best, “I love Centennial!”Parent Review7mo ago - Columbine Elementary School

4/10GreatSchools RatingParent Rating AverageMy son has attended Columbine since preschool and is now in second grade. He’s part of the bilingual program and is thriving in both reading and writing in both languages. He has made many friends, and we truly enjoy being part of the school community. The teachers have been wonderful—warm, supportive, and dedicated.Parent Review9mo ago
