HIRING FREEZE -- Superintendent Harry Pitt told board members that the school system faces a $2.2 million budget deficit in this year's $703 million operating budget.

To help absorb some of the deficit, the school system will leave vacant 75 jobs in central and regional offices, temporarily freeze 85 current job openings in the schools, restrict overtime pay and use of outside consultants and hold off on buying any equipment. Also, any teachers in middle and high schools who leave during this school year will be replaced with substitute teachers.

Pitt said the deficit is largely the result of unexpected increases in fuel costs and expenses for disabled students. Pitt said that fuel prices -- if they remain at the same level for the rest of the year -- will add $1 million to student transportation costs. Private placements of disabled students who cannot be served adequately by the county schools contibuted heavily to an unexpected $1.5 million deficit in the special education budget.

The school's budget problems come amid predictions of county officials that the entire county budget could suffer a deficit of up to $65 million in this fiscal year.
