Wright State University is addressing an $11 million revenue shortfall through vacant positions and utility savings — balancing their current budget after enrollment dropped following the school’s transition to a semester academic calendar.

WSU is the latest in a list of colleges and universities that have adjusted their budgets after the semester conversion to deal with lower-than-expected tuition income. Seventeen public schools spent more than $26 million over four years on the transition, and all but three saw their enrollment fall as a result.

WSU’s enrollment dropped 8 percent compared to last year, and half of that enrollment decline was expected, said Mark M. Polatajko, vice president for business and fiscal affairs and university treasurer. WSU’s fall enrollment was 16,762 students, according to the Ohio Board of Regents.

The university balanced its budget with $10.5 million savings from vacancies and $500,000 from lower utility expenses, Polatajko said. The university’s total annual budget is $442 million.

“We’re very confident in our ability to manage this,” Polatajko told the university’s Board of Trustees.

Last month, Sinclair Community College adjusted its budget down $2.9 million to deal with its revenue shortfall and the Columbus Dispatch reported that Columbus State Community College adjusted its budget down $17 million. In November, Hocking College near Athens laid off 23 people and made other personnel changes to address a $4.3 million budget deficit.

WSU and Sinclair did not lay off employees, and Clark State Community College, which also switched to a semester calendar, did not experience a revenue shortfall.
