NASHVILLE (AP) — Laws that create tougher tenure requirements for teachers and crack down on terrorism are among a number of new measures that take effect in Tennessee on Friday.

The tenure law and anti-terrorist legislation are probably the most contentious of the bunch. Both drew protesters to the Capitol throughout their legislative process.

The tenure law requires a teacher to be on the job five years instead of three to get tenure and creates a way for job security to be revoked for poor teaching performance.

Critics of the law say the evaluation system to be used is suspect and that it hasn't been determined how best to rate educators whose subjects aren't covered by the state's value-added test scoring program.
