ST. PAUL — A move to minimize the roll of seniority in teacher layoff decisions is scheduled for its first Senate test.

It’s the first appearance of the measure in the Democratic-controlled chamber this session, where its chances are unclear. Senate Majority Leader Tom Bakk has said he doesn’t support the push to require that evaluations play a role in the decision to lay off educators when school budgets are tight. A hearing was set for Thursday morning.

Opponents say the bill will lead to costly lawsuits and contract renegotiations. They argue schools have other methods of removing ineffective teachers.

Republicans passed the bill through the House, which they control, largely on party lines. The bill, which also streamlines teacher licensing for out-of-state candidates, is a GOP priority this year.
