Results of the administration of the Nevada Proficiency Examination Program in 1988-89 are presented. The program, established by legislation in 1977 and amended in 1983 and 1987, provided for the administration of examinations of proficiency and achievement in reading, writing, and mathematics before the completion of grades 3, 6, 9, and 12. It also permitted the adoption of different standards of proficiency for students with diagnosed learning disabilities. The first of two major assessment efforts under the program involves the administration of a nationally normed standardized test of academic achievement in reading and mathematics in the third, sixth, and ninth grades; in language in the third and sixth grades; and in writing in the ninth grade. These tests are intended to identify those students who might require additional assistance in order to maintain the typical pattern of promotion through the grades. The second major assessment effort involves testing of all 11th-graders in reading, mathematics, and writing, using state-developed minimum competency examinations. Eleventh-graders must pass all three examinations to graduate with a diploma; students have a total of four opportunities to pass the 11th-grade examinations. Texts of statute mandating the testing program, scoring guides for the writing assessment, and common test score scales used in education are appended. Three bar graphs and six data tables are included. (TJH)
