CPEF meaning in Community ?

The Chicago Annenberg Challenge (CAC) was a Chicago public school reform project from 1995 to 2001 that worked with half of Chicago's public schools and was funded by a $49.2 million, 2-to-1 matching challenge grant over five years from the Annenberg Foundation. The grant was contingent on being matched by $49.2 million in private donations and $49.2 million in public money. The Chicago Annenberg Challenge was one of 18 locally designed Annenberg Challenge project sites that received $387 million over five years as part of Walter Annenberg's gift of $500 million over five years to support public school reform. The Chicago Annenberg Challenge helped create a successor organization, the Chicago Public Education Fund (CPEF), committing $2 million in June 1998 as the first donor to Chicago's first community foundation for education.
