This article is specific to Michigan, but has lots of good stuff about teacher churn in general. One of the best things that we can do for students is give them experienced teachers. Our system is not set up to produce experienced teachers. mlive.com I'm kind of surprised that they didn't carry it out to five years. The numbers I looked at a few years ago said that only 50% of new teachers make it past year five. This is the terrible part. Bummer for those folks who give teaching a try and decide it isn't for them, but that has profound and long-lasting effects on the students. Some good stuff at the end about how to address the problem, shout out to Hillsborough county for their teacher retention program.
