Changes in Pell eligibility guidelines over the last year come as Congress struggles to rein in ballooning costs and deficits in the program for low-income students. One change reduces lifetime available aid from 18 semesters to 12. "This means eligible students have less time to complete their degree while benefiting from a Pell grant," said Craig Fennell, director of student financial services at Temple. Temple will look this semester at how many students are losing aid or are in danger of it because of the changes.
