The academic quality is superior with teachers who care. They have music, art and some sports available and the awards are great. The facilities are adequate, and to be honest I don't know much about parental involvement because I am unable to participate at this time. I would recommend this school, yes!

The quality of academic excellence at Union Colony is great, but too much for the students to deal with. It's hard for them to be kids when they have 50 pounds of homework on their backs!You may take whatever music class you like, but their is a very limited set of extracurricular activities, especially the middle school. But that's not the worst part, the worst part is the fact of how much homework each student is required to do everyday is ridiculous!
