The National Action Council for Minorities in Engineering (NACME), in cooperation with the Center for the Advancement of Science, Engineering and Technology (CASET), undertook a national survey of underrepresented minority students in engineering to assess their college experiences in relation to academic performance. Professionals at the college level need a sound empirical basis for designing intervention programs aimed at increasing the number of minority students who graduate from engineering programs. The purpose of this study was to provide that data. A 95-item survey instrument was sent to 2,584 African American, Hispanic, and American Indian students enrolled full time in undergraduate engineering programs at 64 colleges and universities. The survey results are based on responses from 1,206 students. Selected questionnaire items reveal important facts and trends about the students, their perceptions of engineering programs, and their college success. Implications for retention and predicting grade point averages are discussed. The report recommends the following actions: (1) increase scholarships and grants for minority engineering students; (2) establish additional minority engineering support programs; (3) expose students to scientists and engineers at an early age; (4) provide faculty with training in cultural differences; and (5) reduce ethnic conflict on campus. The report includes six graphs and one table. (AF)
