Abstract:
The Revised Key Math is a content-referenced test for children in grades K-9. It can be used for diagnostic, achievement and curriculum assessment purposes. The 13 domains it measures are: numeration, rational numbers, geometry, addition, subtraction, multiplication, division, mental computation, measurement, time and money, estimation, interpreting data, and problem solving. Spring and fall norms are available for converting raw scores to standard and percentile scores as well as grade and age equivalents. The test is administered individually and takes between 30 and 50 minutes. The tester, using small flip charts, shows pictures and diagrams to the examinee and asks progressively harder questions within each domain until three consecutive errors indicate that a "ceiling level" has been reached. Responses are recorded by the tester in a score booklet. For the four mathematical operations sections (addition, subtraction, multiplication, division), and examinee who progresses beyond the first six basic questions continues within the domain by working problems by hand at the back of the scoring booklet. Norms for this test were established on 925 children in 14 states nationwide. Overall alternate-form reliability averages .90 and split-half reliability is in the high .90s. Cross-validation with the ITBS yields an overall correlation of .76. Norms are included in the test kit.
