This publication provides a reference for those interested in conducting comparative studies about North Carolina tests. It includes norms tables and other basic statistical information for all state-developed tests (state-mandated and local option tests where baseline data are available) that were administered during the current accountability cycle. The baseline norming year is shown for each test. These statistics are the product of a method that computes percentile ranks across two or more distributions. State-mandated end-of-grade test norms, open-ended assessment norms, and local option end-of-grade test norms are given for tests for grades 3, 4, 5, 6, 7, and 8. Norms are given for the end-of-course (high school) tests in 10 subjects. Norms are also presented for the High School Comprehensive Tests for reading and mathematics at grade 10. A discussion of using test scores for student decisions is included, as is a glossary of testing and other statistical terms. (Contains 44 tests.) (SLD)
