초록

The Computerized Youth Aptitude Test is an online service that provides the execution and result presentation of the paper and pencil Aptitude Test for Youth, which has been designed by the Human Resources Development Work Information Center in 2002 to aid the aptitude development and career choice of youth from second year in middle school to third year in high school. The objective of the the study is to extract and analyze the items that function differently according to school level and gender with the data gathered through the 2004 Computerized Youth Aptitude Test equating studies, and thereby acquire validity and implication regarding the sub-tests and measurement components. Towards this aim, the items that function differently according to school level and gender have been extracted from 14 among the 15 sub-tests of the Computerized Aptitude Test for Youth (the “Line Drawing” test has been excluded) using the WINSTEPS computer program, which applies the Rasch model. The analysis results are as follows. First, the analysis of the items in the sub-tests that function differently according to school level shows that 87% of the total items in the “Letter Perception” test and 91% of the total items in the “Symbol Perception” test report substantial disparity between the difficulty estimates according to school level. Second, the analysis of the items in the sub-tests that function differently according to gender similarly indicates that 57% of the total items in the “Letter Perception” test and 74.3% of the total items in the “Symbol Perception” test function differently according to gender. To explain this occurrence, the disparity between groups in attention span and sincerity towards item response has been noted, and the discussion about satisfactory familiarity with the test direction and exercise items and rearrangement of the sub-tests has taken place.
