School Reviews
1 10/10/2025
This school district is difficult to review, as many of its choices have been made based on a lack of funding. They tend to push out people who are very highly qualified, in order to hire people with next to no experience with the goal of saving money. I will do whatever I can in any forum that I can to shun them publicly for this.
