Ruth O. Harris Middle School Reviews

By , a Parent on

My son attends Ruth O Harris and has had nothing but good experiences. The teachers and staff have always been very helpful when I have questions/concerns. The teachers communicate with me and I with them so I always know what is going on with my son academically. Ruth O Harris offers a useful tool (The Zangle Website) where grades and assignments can be tracked.

It is a horrible school. My daughter went and was treated poorly because of her race. The staff was also least helpful when I told them this. I would not recommend this school to anybody.
