Don't know muchabout the schools in Kenosha proper but in the suburbs (10 miles west of Kenosha), we have St Alphonsus. Everyone I have talked to likes it.
Case Mfg, Jockey, are a couple of the major employers. Try this link:

We like the small school of Wheatland Center. That serves the New Munster, Salem, Wheatland, Lily Lake, Silver Lake areas. It is a K4-8. They are super nice and have accepted my kids easily (they have been going for just 3 days as we just moved 2 weeks ago).
Pleasant Prairie has good schools too, from what I heave heard. Stay away from Racine though. Hubby works there but commutes the 1/2 hour so we have better schools.
