GreatSchools Rating
The GreatSchools Rating helps parents compare schools within a state based on a variety of school quality indicators and provides a helpful picture of how effectively each school serves all of its students. Ratings are on a scale of 1 (below average) to 10 (above average) and can include test scores, college readiness, academic progress, advanced courses, equity, discipline and attendance data. We also advise parents to visit schools, consider other information on school performance and programs, and consider family needs as part of the school selection process.

The school community is very welcoming and filled with kind people. It's easy to find ways to get involved and meet new people. If there was anything I would change, it would be the facilities on campus. Our bathrooms are quite the mess; dirty, sometimes no soap, and most the bathrooms we have are closed down. It bothers many of us students, therefore, it would be pretty great for that problem to be solved.

The best experience I had was with the staff. You are able to build personal relationships with almost all your teachers and feel truly seen by them. I would change the bathroom availability. I feel like one more restroom needs to be open during the day.

The best part about attending union Mine is the people that you meet. I have met so many amazing people that have changed my life. My favorite was my cross country coach. He basically motivated my to do anything I wanted. Now I'm here apply to college and looking for scholarships. It was truly a great experience and I will definitely it.

Our son is just starting his Sophomore year. After going to 13 -yes 13- different high schools myself, I must say, Union Mine is an absolute joy! They are extremely student focused. The block schedule is amazing. Special "D-back" days allow kids to either make up missed work or enjoy extra-curricula...
