The nation's top educator headed back to class Wednesday warning states against taking money from their youngest students.
"We're not going to balance the budget on the backs of our young children. We just can't afford to do this," said Secretary of Education Arne Duncan.
All but 12 states pay for pre-k programs.
The federal government also funds head start, for low-income kids.
Last year, states added more than 100,000 new preschoolers and spent a billion more on them than the year before.
But with five billion in federal stimulus money on the way at least nine states may cut their own funding so there's little if any net benefit.
Advocates say that would hurt the middle class.
"Children whose families are just above the poverty line all the way up to the median income have less chance of being in a good preschool program than children in poverty. And for children in poverty, it's less than 50 percent," said Steve Barnett of the National Institute for Early Education Research
