Under the California Assembly Bill 665 of 1972, the state assessment program must test all students in grades 1, 2, 3, 6, and 12 in reading skills, and those in grades 6 and 12 to assess their skills in effectiveness of written expression, spelling, and mathematics. The state may develop its own tests, and a matrix sampling approach may be used for collecting data. This document deals with the test content specifications in mathematics. Operationally, the basic skills in mathematics were defined by a matrix consisting of five traditional mathematical content areas and three levels of cognition. The five mathematical content areas are arithmetic, algebra, geometry, measurement, and probability and statistics. The three cognitive levels are computation and knowledge of facts, comprehension, and application. Items that provided a sampling throughout the matrix were chosen for the testing program from a pool supplied by cooperating test publishers. (BW)
