Board member Leland Lemley said he supports driver's education, but cutting it could end up being a financial necessity.
"There may come a time in the next year or two when we have to make that decision," he said.
The part-time physical education position is tied to the driver's education program due to some staff changes, Robertson said.
The superintendent told the board he feels it is important to have a good person in the librarian position.
"We lost two candidates already," Robertson said of the hiring delay.
Other district librarians addressed the board during a public comment session Tuesday to lend their support to hiring a trained professional.
"A library media center is a wonderful place where wonderful things happen," said Mary Lee Yaukey, library department chairwoman.
Students start arriving at 7 a.m. to take advantage of resources, Yaukey said. Up to three classes are taught at once in the library, she said.
One study found that schools with good libraries (determined by budget, size of collection and staffing) had better scores on Pennsylvania System of School Assessment standardized tests, according to middle school librarian Catherine Beatty.
"They discovered the libraries with adequate staffing scored 10 to 15 percent higher on PSSA scores," she said.
The board agreed to fill the position and Robertson said he'd return to it with a candidate.
Both the physical education and librarian votes were 6-1. Board members Lemley, K. Marilyn Smith, Pat Heefner, Ed Wilson, Firmadge Crutchfield and Billie Finn voted in favor. Board member Chris Lind voted "no." Board members Bonnie Bachtell and Brenda Lucas were absent.
