I was doing some research and came across this presentation from PSERS. This was a presentation given to Upper St Clair School District in late March.
It is long and detailed but if you have the time, it may be worth it to page through the 60 page presentation. The conclusion is that there is no silver bullet that will stop the PSERS rate spikes. There are some possible options to limit the rate spikes, but nobody knows for sure what will happen.
