My son is headed to 6th grade at WMS next year and I've gotten quite the opposite impression from parents I've spoken with. They all say the "team" approach is really nice. Every kid is put in a group ("team") and they travel with that team through the entire 3 years there. They also keep the same counselor and vice principal for all 3 grades, so there are administrators who really get to know your kid. There are lots of after school activities and they seem to have a lot of counseling supports in place, which I've heard are very helpful.

There are a bunch of kids on my street who go there and they chat with me and tell me how much they love it. I was quite surprised because my jr. high experience was brutal, but they all seem really happy.
For what it's worth.
