An analysis and summary are presented of the 1989-90 test results of New Mexico students on the Enhanced American College Testing Program (Enhanced ACT) and the Scholastic Aptitude Test (SAT). Data were provided by the American College Testing Program, the Educational Testing Service, and the New Mexico High School Graduates Survey. The Enhanced ACT scores of students in New Mexico remain below the national averages, but above state averages for the southwestern United States. Enhanced ACT composite scores remained nearly steady as did mathematics scores for the past 3 years. Enhanced ACT English scores decreased in 1989-90. Males outperformed females on the Enhanced ACT, although female composites increased in 1989-90, while male composites continued a 4-year downward trend. The Enhanced ACT scores of minority students showed some improvement, especially when the students were involved in a core curriculum. SAT scores of students in New Mexico were above the national average, although verbal scores and mathematical scores declined in 1989-90. Males continued to score higher than females on both the verbal and mathematics examinations in New Mexico and on a national level. Eleven bar graphs and six tables present data on student achievement, including sex and ethnic differences. An appendix lists ACT results for New Mexico by school district. (SLD)
