The city could lose $129 mil­lion a year in Head Start funding if it doesn’t fix six serious problems in child facilities, the feds told the City Council Wednesday.

“If any of the six deficiencies are determined to be uncorrected, [the feds] will proceed with a notice to terminate ACS’s Head Start grant,” said Evangeline Santiago-Artesona, a Children and Families Program specialist with the Department of Health and Human Services.

The city’s Administration for Children’s Services is the nation’s largest recipient of Head Start funding.

But ACS was called out in a scathing federal report for issues like child-care facilities with rodents, hazardous furniture and unsupervised kids.
