I have neighbors whose children attend middle school in Bowie, and they haven't had any complaints.
Bowie High is a huge school, which I think brings down the scores. But I'm told they have a really good enrichment program for advanced students. I don't know the details of getting in, but I imagine it has to do with scores.
The key seems to be that if your middle school/high school kid is placed in the upper levels, then there isn't a problem. The problem is in the lower levels. It isn't that all the kids in the lower levels are bad kids or bad students, but because it's a larger pool of kids, there is a greater chance of having disruptive students in the class.
