School Reviews
3 10/10/2025
Chatsworth is not the school we thought it would be. The administration is focused on test scores and keeping a select group of parents happy. Bullying is rampant and the school is controlled by a group of wealthy parents. If your child struggles but is not absolutely failing, he/she will be ignored and passed from one grade to the next (passing the buck is a theme here.) School administration is ineffective and the "community" and "mindfulness" they preach are a joke. Not worth your tax dollars!
