The Illinois State Board of Education says at least 21 districts have canceled the "Summer Bridge'' program.
The main reason was that the state budget had not been signed into law, and districts were afraid to start the programs and then find out there was no money for them.
In most years, the governor signs the budget in early June and there is little question about how much money will be available to schools.
But this year, Gov. Blagojevich didn't sign the budget until July and used his veto power to make some changes.
The State Board of Education is still figuring out how much money schools will get this fall.
