The DeKalb School Board is now considering five options that could slash $90.9 million to $119.2 million from the school district’s 2011 budget that goes into effect on July 1.

The options, offered Monday, are the latest in the district’s ongoing attempts to balance its upcoming budget in the face of an $88 million revenue shortfall.

All the plans include cutting 154.5 positions from its central office, the closing of four elementary schools in the fall, and slicing $10 a day from the pay for substitute teachers.

Board members also need to choose between cutting salaries across the board or offering furlough days and whether to increase class sizes by one or two students.

The budget comprising job losses, school closings and school program reductions comes in the wake of a deficit that grew from $55 million as the county’s tax digest was revised. The county’s tax assessors now anticipate a $2 billion decline in property tax revenues.

Other cuts under consideration by the school board include reductions in the employees health and wellness program, athletics, summer interns, and paraprofessionals.

Property tax increases of 1 to 2 mills are proposed for three of the five plans. School taxes already account for 67 percent of DeKalb homeowners’ property tax bills.

In a district-sponsored survey, employees overwhelmingly supported moving to a four-day workweek to save money, but this option was not considered in the budget proposals.

District 4 board member Paul Womack said Wednesday the four-day week is not being discussed at this time.

“It might come up later,” he said.

The board plans to adopt a proposed budget at its April 12 board meeting. It will seek public input at two public hearings on April 21 and 28.

It must adopt a balanced budget by May 10.
