The Government Contracting Assistance Center (GCAC) is a Procurement Technical Assistance Center (PTAC) operated by Slippery Rock University of Pennsylvania. GCAC provides assistance to businesses interested in pursuing federal, state and local government contracts and subcontracts.

GCAC was established in 1989 as a collaborative effort between Slippery Rock University of PA and California University of PA's Government Agency Coordination Office (GACO).  For over 20 years, the GACO/GCAC program has been working cooperatively to provide government contracting assistance to companies in the region.

The GACO/GCAC program receives funds from the Defense Logistics Agency and the Sarah Scaife Foundation.
