Head Start programs across the country eliminated services for 57,000 children in the coming school year to balance budgets diminished by the federal sequester, cutting 1.3 million days from Head Start center calendars and laying off or reducing pay for more than 18,000 employees, according to federal government data scheduled for release Monday.

The latest numbers, based on the results of “reduction plans” Head Start grantees submitted to the Department of Health and Human Services, fall short of earlier predictions by the Obama administration that 70,000 children would lose access to preschool because of the mandatory 5 percent cuts. But the cuts will still affect tens of thousands of poor families across the country who rely on Head Start for early learning programs, day care and a network of social services and medical care.

Some Head Start centers focused on cutting administrative and support services, such as transportation. Others chose to shorten the school year or the school day. The latest figures show that 18,000 program hours will be cut next year by centers that will start later in the day or end earlier.
