NASHVILLE (AP) — Tennessee education officials say they're taking steps to address teachers' concerns about a new evaluation system that for the first time will use students' standardized test scores as part of the process.

Recent changes in state law — including teacher evaluations and toughening the curriculum — allowed Tennessee to win $500 million in the national Race to the Top education grant competition.

However, The Associated Press recently obtained a list of about 30 questions teachers say remain unanswered about the evaluation process that is broken down into 50 percent qualitative — or the observation component — and 35 percent growth and 15 percent achievement.

Critics say the evaluation system is suspect and hasn't determined how best to rate teachers whose subjects aren't covered by the state's value-added test scoring program.
