This summary report provides information about three of New Mexico's statewide assessments in 1997-1998. In spring 1998, the CTBS5/Terra Nova Survey Plus achievement test was administered to approximately 65,000 students in grades 4, 6, and 8 as part of the New Mexico Achievement Assessment Program. With three exceptions, the median national percentiles for students in New Mexico were slightly lower than the 50th national percentile. The New Mexico Writing Assessment Program is a direct, on-demand assessment in which all students in grades 4 and 6 participate. Although the examination is not mandated for grade 8, school districts have the option of using an eighth-grade version. Writing Assessment scores are reported for grades 4 and 6. The New Mexico High School Competency Examination is a graduation requirement that assesses competencies in writing, reading, language arts, mathematics, science, and social studies. Students take the test for the first time in grade 10. In 1998, this examination was administered to 20,157 10th graders. Results are presented for these students overall and by ethnicity and individual subtests. (Contains 13 tables and 11 figures.) (SLD)
