Lawmakers will be burning the midnight oil at the statehouse Tuesday.
Senators began working on education reform around 4 p.m. and they are expected to debate through the night before voting on one of their highest priorities of the session.
There are three different versions of the bill, one by the senate, one by the house and one by the governor.
The senate bill being debated Tuesday is the most expensive. It calls for 4-percent allowable growth for two years and sets starting teacher pay at $35,000.
The senate version of the bill passed along party lines 26 to 23.
House republicans passed their version earlier this year, offering a smaller raise for starting teachers and making the incentive pay system optional.
Lawmakers from both sides will now have to find middle ground on their two plans.
