Scarborough voters will go to the polls Tuesday to consider a $42.5 million school budget proposal for the coming fiscal year that represents a 7.6 percent increase over current spending.

The School Board made some last-minute changes to the budget last week, after the Town Council voted 4-2 Wednesday to reduce the spending proposal by $587,000. Councilors pushed for a smaller school budget to hold the town’s overall tax rate increase at 3.5 percent.

School board members agreed Thursday to reduce spending by about $387,000 and take $200,000 from a surplus account to cover the remainder of the council’s budget reduction.

The changes won’t cause any layoffs or program eliminations, but they are expected to reduce the number of added positions in the budget.

The polls will be open for Tuesday’s referendum from 7 a.m. to 8 p.m. at the municipal building on Route 1.
