The University of Chicago Consortium on Chicago School Research (UChicago CCSR) builds the capacity for school reform by conducting research that identifies what matters for student success and school improvement. Created in 1990, UChicago CCSR conducts research of high technical quality that can inform and assess policy and practice in the Chicago Public Schools. UChicago CCSR studies also have informed broader national movements in public education. UChicago CCSR encourages the use of research in policy action and improvement of practice but does not argue for particular policies or programs. Rather, UChicago CCSR helps to build capacity for school reform by identifying what matters for student success and school improvement, creating critical indicators to chart progress, and conducting theory-driven evaluation to identify how programs and policies are working.
