The survey by the Pennsylvania Association of School Administrators and Pennsylvania Association of School Business Officials released Tuesday received responses from 281 of 500 districts.
Just over half expect their finances to worsen next year, up from about 40 percent in last year's survey.
Meanwhile, three in four expect to tap reserves and reduce staff. Three in five expect to increase class size and reduce elective course offerings. About half expect to increase taxes and reduce or eliminate field trips and extracurricular activities, including sports.
The groups blame cuts in state aid, rising costs and lackluster local tax collections.
