The Business and Dental schools have run out of 1980-1981 work-study money because of program changes and rising tuition costs.

Both schools get small work-study allocations because their students have little time for outside jobs, Lawrence E. Maguire, manager of the University work-study program said Thursday. But he added that this is the first time either schools has used up its money so early.

Diane Spinell, financial aid officer at the Dental School, said Thursday, "Since our students are normally in school 11 months a year, we usually wind up using only half the money given us. This year the school switched to a five-year curriculum, giving the students a ten-week break between first and second year. Many students spent the time working," she added.

Evelyn Baker, a financial aid official at the B-School, said she does not know why more students are using work-study money. The program is open only to students working for non-profit organizations, so generally only a few B-School students use it.

Both the Dental and Business Schools have been forced to deny students work-study money. "We have a few students who have incurred their loan limit, and need another source of money," Baker said, adding that several would decline a non-work-study job because they "see it as menial labor."

Although officials refused to release this year's work-study allocations, in 1979-1980 the B-School received only $8 000 of the total $2.23 million divided among ten graduate schools. The Dental School received $15,000.

Tamara Rogers, director of student employment at the College, said yesterday that this year a higher percentage than usual of undergraduates eligible for work-study money have decided to take it.

Under the work-study program, the federal government pays 80 per cent of a student's salary. Many University jobs are open only to work-study students.
