Open Thread: Does Any State Have A Quota For How Many Teachers Must Be Rated "Ineffective" Every Year?

The last 24 hours we've gotten an indication that Governor Andrew Cuomo and Regents Chancellor Tisch will look to impose some kind of "quota" on the percentage of teachers that a district must rate "ineffective" every year (see here and here)

This news comes after education reformers have complained that there weren't enough teachers rated "ineffective" either statewide or in New York City.

So here's a question I have for you out there:

Are there any states that have a quota for how many teachers have to be rated "ineffective" every year and, if so, how does that system work?
