School Reviews
2 10/10/2025
This is the worst school I've ever worked for. The administrators are horrible. The superintendent will make your life hell if you do not agree with everything she wants to do or says and the principal tends to not do much of anything. Many of the teachers have worked in the district for years (15+) and are now just waiting it out until retirement. One certain teacher spends more time out of his classroom than in (even when he has students). Grades are badly inflated. If you as a teacher actually do your job and grade fairly you are punished (which is a disservice to the students). This is probably why many students are functioning academically at an elementary level. Most of the students are lazy and disrespectful/mean to teachers and other students. There are currently no art classes and the music teacher just left, but the wood shop classes are outstanding. Athletics come first at this school and academic awards are a joke. The actual school building is nice except for the water (it has bacteria and an unsafe level of arsenic in it). Some classes do not even have text books for the students. I could go on and on but hopefully by this time you get the picture. As a previous educator for this school I would NOT recommend working here. If you want you child to get a quality education send them some place else.
