Went from being respected by peers and teachers at my old school to ridiculed and laughed at by the entire class.Other Review2mo 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 Review4mo ago - Foothill Elementary School

8/10GreatSchools RatingParent Rating AverageMy 4th grade teacher was really mean I hope they're doing horrible my 5th grade teacher lives in my neighborhood so I can't really say anything negative about them they were pretty nice anyway tho and my third grade teacher was mean and then started not being mean I was only there for 3 year and it contributed to my mental health issues and set me up for failure or something idk my friends were really mean and I hated the principal that was probably why I hate this school so muchOther Review2y ago
