Abstract	New legislation in 1972 shifted the emphasis of the California Assessment Program (CAP) from traditional every pupil achievement testing to a more efficient multiple-matrix testing design, under which a broad spectrum of skills could be surveyed without undue expenditure of educational resources. Scale score reporting was introduced to the grade 6 assessment in 1981-82. The purpose of the present report is to document activities undertaken in this endeavor. After a brief review of the fundamentals of CAP measurement models, the following topics are considered: (1) structure of the assessment instrument and the delineation of skill areas; (2) item calibration procedures and results; (3) scoring procedures for a single school in a single skill element, then for aggregations of schools and/or skill elements; (4) method of approximating results for demographic subgroups within schools; and (5) equating of results from the prior grade 6 surveys to the new score scale. Appendices include (1) Calibration of Skill Element "Classification of Numbers": One- and Two-Parameter Logistic Models; and (2) 1981-82 Grade 6 Item Parameter Estimates. (LMO)
