SCHOOLS in Pennsylvania ought to be celebrating. The state gave them a $125m budget increase for 2017-18—enough for plenty of extra books and equipment. But John Callahan of the Pennsylvania School Boards Association says all the increase and more will be eaten up by pension costs, which will rise by $164m this year. The same happened in each of the previous five years; cumulatively the shortfall adds up to $586m. The pupil-teacher ratio is higher than in 2010. Nearly 85% of the state’s school boards said pensions were their biggest source of budget pressure.
