School Reviews

I went to union school district (K-12) and I also have two children that attend these school. In my opinion it is a great school district! The teachers and staff genuinely care about the kids and they care about their education. I feel these stats are pretty low for our school and they are also outdated. They also are compared to much bigger schools with much bigger class sizes. I`m glad my children attend union and I`m proud to say I granduated from there!
