The Higher Education Opportunity Program (HEOP) at New York University (NYU), which serves economically and educationally disadvantaged residents of New York State, is described. The HEOP provides supportive services, including a pre-freshman summer session, credit and noncredit courses in basic skills, individual tutoring, and personal and academic counseling. Economic disadvantage is based on family income adjusted to number of household members, while academic disadvantage is defined in terms of Scholastic Aptitude Test (SAT) scores. Transfer students from other opportunity programs in the state are also considered for admission. Information is provided concerning: the SAT scores for entering HEOP freshmen 1976-1981; high school averages for entering HEOP freshmen 1976-1981; high school averages for entering HEOP freshmen, 1975-1980; the distribution of averages for students who have completed the freshman year at NYU; the ethnic breakdown of HEOP students; the distribution by race and sex for HEOP students, 1977-1982; graduation/attrition for HEOP freshmen, 1976-1981; and a breakdown of state, federal, and institutional sources of financial aid for HEOP students. Since its inception in 1970, the HEOP at NYU has graduated more than 700 disadvantaged students. Since 1975, more than 60 percent of all HEOP students have been graduated annually, compared to a statewide HEOP annual graduation rate of 57.2 percent in 1980-1981. Of 1,422 transfer students entering in fall 1975, 800, or 56 percent, graduated within 4 years. It is suggested that in measuring program effectiveness, attention should be directed to academic and economic eligibility criteria, personal factors that may impede student progress, academic predictors for measuring potential success, quality and use of supportive services, and reasons for program separation before graduation.
