In an effort to achieve ethnic parity for underrepresented minorities at the University of New Mexico College of Engineering, precollege and undergraduate programs were developed to recruit and retain Hispanic and American Indian students. The Math, Engineering, and Science Achievement (MESA) program is a coherent, longitudinal program organized to increase awareness and motivation in bright minority Algebra I students and to support their interest through high school graduation and university matriculation. It provides such student services and activities as short on-campus college/engineering orientation programs; tutoring; academic, university, and career counseling; field trips; summer enrichment and employment programs; and scholarship incentive awards. The undergraduate program supports minority students through the Hispanic Engineering Professional Advisory Committee and the Hispanic Engineering Organization, the Native American Program/College of Engineering, and the College of Engineering tutoring program available to all engineering freshmen. Comprehensive tabular data indicate student ethnic breakdowns for program participation, college enrollment, degree received, and sex. Figures for corporate contributions and federal funding are included. (MM)
