The MCPS Office of Shared Accountability conducted an evaluation of the "High School Plus" (HS+) program implemented in Montgomery County (Maryland) Public Schools (MCPS). HS+ is one of the intervention programs offered by MCPS to provide additional ways of earning high school credits for students who have failed courses required for graduation. The overall goal of the evaluation was to examine the nature and extent of benefits to high school students served by the extended-day HS+ program. The evaluation findings suggest that although attendance is a problem, the HS+ program: (1) serves students who are at risk of dropping out or academic failures; (2) provides an opportunity for students to earn missing credits and also earn credits for a failed course; and (3) helps some students learn better than the traditional course. The report provides recommendations and includes the appendix: High School Plus Program Outcome Evaluation.
