School Reviews

The teachers are, for the most part, professional and consistent. Extracurricular activities are vastly upheld and the men and women who coordinate them work very hard. This school is a small-town high school, obviously, yet everyone finds their niche. Administration is slightly inert but the guidance counselors are excellent. Sports are great; the music programs are just as great, if not better. Do not forget that the teachers of the Milburn (freshman) campus are trained and experienced in high school education. So, they will not be keeping your child in middle school standards, although the building is quite detached from the rest of the high school. They will be treated as high schoolers. Also, true maturity is not based on imitating elders (the sophomores, juniors, and especially seniors.) Exposure to the students of those grades is not absolutely necessary. Allow your child to rise above the rest, through their own experience, and it will stick longer than impression of emotional aging that is created just for peer approval.

I am currently a freshmen at O'Fallon Township High School after I moved from New York. I was originally goig to move to St. Louis but my mother found out what a great school it was and couldn't resist. Academic Programs are excellent and their extracurricular activities are amazing! Everybody comes out to the school sports and attend the music concerts. In the back of the school handbook there are pages filled with different types of clubs and activities. The level of parent involvement is awesome! I recently went to a girl's lacrosse game and there was a team of mothers selling candy and snacks to help raise money for the girls.
