The Milwaukee Parental Choice Program (MPCP) began as the nation’s first urban school voucher initiative in the fall of 1990. Initially, seven secular schools were authorized to enroll the 341 students who first participated in the program. By the 2006-07 academic year, a total of 17,749 voucher students were attending one of the 122 private secular and religious schools that participated in the MPCP or “Choice” program for the entire year.
