High school students who complete a new Wisconsin program to promote college attendance will be eligible for annual grants worth $250 to $2,500 for their first two years of college, Gov. Jim Doyle said Monday. Doyle also said Wisconsin Covenant scholars would be eligible for additional aid during their final two years, with the amounts depending on the availability of funding. At a news conference at the University of Wisconsin-Madison, Doyle said the grants for low-income students, when paired with other state and federal aid, would be more than enough to cover tuition and fees. And he said the $250 grants for others would recognize their accomplishment and slightly reduce their financial burden.
