Jeremy Hobson: Well Congress is still working on a $1 trillion spending bill ahead of a midnight deadline tomorrow. And it appears federal student aid programs are on the chopping block.

From the Marketplace education desk at WYPR in Baltimore, Amy Scott reports.

Amy Scott: When college students take out loans subsidized by the federal government, Uncle Sam pays the interest for the first six months after they graduate.

Terry Hartle is with the American Council on Education. He says Congress is expected to end that grace period.

Terry Hartle: The good news is that the cuts that we are looking at are far less than almost every observer predicted four or five months ago.

The savings on interest payments will help pay for federal grants to low-income student under the Pell program. But Hartle expects cuts there too. He says students will only be eligible for grants for six years instead of the current nine. And they'll have to have a high school diploma or an equivalent.

Mark Kantrowitz with Finaid.org says those students are more likely to graduate.

Mark Kantrowitz: If the goal of spending federal money is to produce college graduates, you'd want to focus that funding on the students where it's going to make a difference.

But Congress may also make it harder to qualify for the maximum Pell grant, about $5,500 a year. And that could price more low-income families out of a college education.
