DES MOINES, Iowa (AP) -

Not long after Republicans in the state House scaled back Gov. Terry Branstad's education plan, Democrats in the Senate have beefed it up again.

The Senate education legislation was introduced Monday. It boosts minimum teacher pay back to the $35,000 proposed by Branstad and mandates participation in a leadership program that would provide additional compensation to teachers who take on more responsibilities. Sponsor Sen. Herman Quirmbach says there will be several options for how districts set up those programs.

Last month, the House approved an education plan that set minimum salaries at $32,000 and gave districts the ability to opt-out of providing salary increases or setting up the teacher leadership program.

A spokesman for Branstad says Tuesday the governor would review the Senate plan.
