BATON ROUGE, La. (AP) — Louisiana's 60,000 public school teachers are about to face their first job evaluations under a new review system that continues to spark controversy and questions.

The overhaul stems from a 2010 law pushed by Gov. Bobby Jindal. It is supposed to improve teacher quality, in part by linking annual job reviews to student performance.

Classroom observations by principals and others, which have been used for years, have also been revamped.

The Advocate reports now teachers will face two-part job reviews that are causing some nervousness.

The heart of the new system will apply to about 20,000 of the state's teachers in math, English and other subjects that are subject to objective tests.

The other half of the review will be based on the classroom observations.
