States push to pay teachers based on performance

Dorie Turner:

For parents and politicians hungry for better schools, the idea of paying teachers more if their students perform better can seem as basic as adding two and two or spelling “cat.”
Yet just a handful of schools and districts around the country use such strategies. In some states, the idea is effectively illegal.
That could all be changing as the federal government wields billions of dollars in grants to lure states and school districts to try the idea. The money is persuading lawmakers around the country, while highlighting the complex problems surrounding pay-for-performance systems.
Some teachers, like Trenise Duvernay, who teaches math at Alice M. Harte Charter School outside of New Orleans, want to be rewarded for helping students succeed. Duvernay is eligible for $2,000 a year or more in merit bonuses based on how well her students perform in classroom observations and on achievement tests.
