Abstract

In a test, the final score was obtained as a composite of factors built up the test. The factors load in a test, would affect reliability of score of a test as composite of its factors. This study compared the reliability of the composite scores of mathematics test regardint its the loading factor. This study used the national examinations data of mathematics test in Junior High School, which was then analyzed using exploratory factor analysis to determine the loadingfactor in many cases basics on factors and long of the test. Furthermore the reliabilities estimated, and then compared with the H*-test and the Hakstian and Whalen test. The results showed that the analysis of 1-factor, the coefficient of reliability on a set of 20 items and a set of 25 items are higher than the original test load of 30 items. In the analysis of the two factors, the coefficient of reliability on a set of 15, 20, and 25 items are higher than the original test load of 30 grains when analyzed by one factor. In the analysis of the three factors, a set of 20 and 25 items have higher reliability coefficient compared with the original test load of 30 items when analyzed by one factor. Key words: reliability estimation, composite score, mathematics test
