Schools Superintendent W. Spencer Mullin retires in March and school officials are predicting that looming budget problems will face both interim Superintendent Elaine Espindle and the next permanent schools chief, who the School Committee expects to hire by the end of the school year.

Dracut schools have been waiting for $1.6 million in federal education dollars since September. The money is supposed to pay the salaries of 17 teachers and employees, as well as school supplies, technology and other expenses. State officials are telling Dracut that money is coming in March, but School Committee members worry what will happen next year when that federal stimulus money is expected to dry up.

“I know money doesn’t solve problems, but you do need some,” School Committee member Bonnie Elie said recently.

With the uncertainty about the economy and state funding for schools next year, the school-budget process is expected to be rocky. There may not be many places in the budget where the school system can make cuts in a district where spending per pupil is one of the lowest in the state.

The town spent about $9,203 per student in fiscal 2008, the latest numbers available from the state. Only four school districts — Douglas, Georgetown, Grafton and East Bridgewater — spent less per student than Dracut in fiscal 2008, according to state data. The state average for spending per student for that same period was $12,448.78.

While school officials are learning to do more with less, the district is also projected to grow by 89 students by the 2012-13 school year, according to school officials.

Last month, Mullin announced he expects the state to cut its funding to Dracut schools next year by at least 10 percent. To make up for the expected shortfall, school officials have been brainstorming ways to cut costs — everything from eliminating bus stops to closing Parker Avenue Elementary School and sending students there to the three other elementary schools in the town.

The move to shut Parker Avenue could be a battle, with angry parents arguing that officials shouldn’t shut down the only Dracut elementary school to meet state standards for progress on MCAS scores last year.

Dracut High School and Englesby Intermediate School were the only other Dracut schools to join Parker Avenue on that list. State education officials listed the Campbell Elementary, Brookside Elementary and Lakeview Junior High on the list of schools that need to improve on MCAS scores.

“Like all school systems, we’ll be facing challenges, but I think we have a dedicated and senior staff here that help the new teachers,” said School Committee member Ron Mercier. “There’s always challenges, but I think you have a school committee that’s going to work with a superintendent and help them as much as we can. If we can allocate some funds from (the school choice fund) it can help funding problems for some programs. We want to make sure the MCAS scores stay up.”
