PSLF use limit

So I'll be starting PT school next month but already have all my current loans on the PSLF program (undergrad and masters). I went ahead and 'grandfathered' these loans in so that if the doomsday scenario of the program getting axed occurs I'll be ok. Provided they honor loans already on the program.

Does anyone know if I'd still be able to use the program for new loans after PT school? Just curious how this would work.
