Since its founding, CSG’s Compact Center has worked to promote the use of interstate compacts as an ideal tool to meet the demand for cooperative state action.  During that time there have been approximately 180 adoptions of CSG supported compacts, including 10 separate adoptions of different projects during the 2014 legislative session. Two of those compacts have expanded to all 50 states, while the Educational Opportunity for Military Compact has now grown to 48 states.  Below is a summary of various CSG compact projects.

With the additions of New Jersey, New Mexico, South Dakota, and Utah during the 2010 legislative session the Interstate Compact on Educational Opportunity for Military Children has grown to 30 member states, ensuring that approximately 85 percent of the impacted population is now covered by the compact.
