HARRISBURG (KDKA) — The Pennsylvania School Employees’ Retirement System Board has voted to raise contribution rates.

Those rates will be for tens of thousands of public school employees.

This all comes after a mistake in a calculation of the fund’s long-term investment performance was revealed last month.

The board voted to raise pension contribution rates starting next July 1 for about 94,000 public school employees all hired in 2011 or later.
