Many local school districts will ask voters Tuesday to approve budgets for the 2015-2016 school year.

But the actual figures may change after the fact because, as in past years, districts are finalizing their budgets before state funding has been decided.

Districts have calculated how much state aid they would receive if Gov. Paul LePage’s proposed budget passes, but the Legislature’s Appropriations Committee is proposing to increase the amount of education aid by $25 million per year.

With budget validation votes happening before a state budget is in place, school administrators have to go with the figures they have. The Maine School Management Association sent districts specific wording for warrant articles to enable them to use any extra money they might receive to lower taxes or increase school expenses without having to hold a second round of votes. Schools also may carry over any unanticipated state funds to the next school year.

Here are details for Tuesday’s school budget referendums in Greater Portland. In some cases, the tax impacts of school budget proposals were not available in budget documents or could not be calculated because of changes in overall valuation.
