Educational Transfer from friend/t back to P/t

During the last few years I've been attending college (3 classes a semister) alongside with working ridiculous hours as a swing driver. I have recently realized that the medical field has a fervent calling for me, and I'm slightly curious to know if UPS allows employees that are FT status to transfer back to PT status for educational purposes? My original objective was aimed toward obtaining a management position, but I've since realized otherwise... Any info will be greatly appreciated, thnx
