This report exam­ines how demographics and outcomes changed when schools that had enrolled a dis­pro­por­tion­ate share of the sys­tem's white stu­dents entered the city's cen­tral­ized enroll­ment sys­tem in New Orleans. It finds that the schools enter­ing that sys­tem (OneApp/?NCAP) led to increased access to those schools for Black and oth­er non­white stu­dents. While schools have been reluc­tant to give up con­trol over enroll­ment, these schools did not see declines in white enroll­ment or aca­d­e­m­ic per­for­mance after join­ing the enroll­ment system.
