The Stanford Achievement Test (SAT), Test of Academic Skills Level I was administered to 10,186 tenth grade students in Hawaii during fall 1984. This two-section report presents findings from the SAT's mathematics subtest. This subtest measured students' competency in these nine areas: numbers, symbols, and sets; number properties and operations (whole numbers); number properties and operations (common and decimal fractions); number properties and operations (integers and exponents); mathematical sentences; geometry and measurement; ratio and percent; graphs, probability, and statistics; and mathematical reasoning. Section I, an overview, discusses the purpose of the test, the background of the test administration, and the approach for program analysis; a general summary of performance is included. Section II provides analysis of the mathematics subtest relative to the task requirement, student performance in Hawaii compared to national performance, implications, and recommendations. Supporting documentation (including SAT objectives correlated with learner objective or performance expectation) is included in appendices. The statewide summary of group stanine results indicates that tenth grade students in Hawaii performed slightly better than the national norm population with 78 percent scoring in the average and above average ranges. This is 1 percent higher than the national norm of 77 percent. (JN)
