Originally established by NSF in 1979, EPSCoR supports the development of scientific infrastructure that enhances in a state science and engineering (S&E) capacity. It was created in response to Congressional concerns about geographical concentration of Federal funding of academic research and development (R&D). Currently, there twenty-seven states along with Puerto Rico and the Virgin Islands are EPSCoR states. The Center for Science, Technology and Environmental Policies Studies (CSTEPS) and affiliated faculty are conducting longitudinal evaluations of NSF EPSCoR programs. Evaluations are both formative and summative in design and intent. CSTEPS is currently evaluating the Kansas NSF EPSCoR Track I project.
