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 - Vejar Elementary School

8/10GreatSchools RatingParent Rating AverageThis is our 3rd year at this school (k-2nd) two of our children currently attend. We love the staff, we love how involved the principal is, and have had some great luck with teachers. My children are truly cared for and we are looking forward to my daughter starting TK next year.Parent Review4y 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
