9/10GreatSchools RatingParent Rating AverageBeen going to Collegewood since kindergarten and my son is now a 5th grader. We are more than pleased with the school, staff and education! We are going to be very sad to learn next year but I’m so happy with the education he was able to get the last 5 years. The staff is always super helpful and the principal makes the school super fun! She’s so engaged and gets involved with every class and student.Parent Review2y ago - Suzanne Middle School

10/10GreatSchools RatingParent Rating AverageAbsolutely atrocious. Students were not taught the difference between right and wrong. Teachers do absolutely nothing to stop bullying. Also, according to the office manager, my kid- along with a few others are the only ones that passed the state tests.Parent Review7y ago - Walnut High School

10/10GreatSchools RatingParent Rating AverageThis is my last year in high school for me but that doesn’t mean I can forget about walnut high school. Through out my years at walnut high school I have learned a lot from them and that is because of the counselors, our teachers and principal. Without them we as students wouldn’t have gone far in high school. All of the sports and really good because of the couches we have and there dedication to the team and to the school. So I would definitely recommend walnut high school for your kids.Student Review5y ago
