A strict public school in Leawood, Kansas, and makes you want to go to a private school. While sitting in the office of this school you can watch the security tapes, or watch the fat kids come out of the nurses office with an ice pack. Mission Valley is also the school with the ESL (english as a second language) program where all the immagrants come from all around Kansas City and try to kill the kids from KCK. It's not very pleasant, some of the Chinese kids try to knife the Mexicans, and the Mexicans hit on the Blacks, while the blacks are into the white trash...its pretty much a horrible school.
Mission Valley Middle School is a place that you never want to go.
