School Reviews
5 9/26/2007
The quality of academic programs at Grattan is average/above average. There is a band/choir program which is awesome. The school had an equestrian team compete in the MIHA for the first time this year, 2007. They also have boys and girls basketball and girls soccer also. The Equestrian team took 2nd place out of the 4 teams in their division this year. The facilities are great. The school is only @ 4-5 years old and kept in excellent condition. Parents are very involved!
