The purpose of this study is to develop and standardize a Vocational Aptitude Test for the Deaf Adolescents(VATDA) with a Korean Sign Language(KSL) Video by examining the difficulties of each item and analyzing the reliability and validity of scale. CareerNet Vocational Aptitude Test(CVAT)(Lim, 2011) is self-reported test. 10-item measure vocational aptitude of hearing adolescents. The pilot version of the VATDA is translated from its original material and new items related ‘KSL abilities’ for subtests are included. CVAT was translated using a three-steps back translation methode. In the first step, a deaf professional KSL instructor translated the scale items from written Korean into KSL onto a videotape. In the second steps, 2 certified interpreters, unfamiliar with the CVAT, translated the videotaped version back into written Korean. In the third step, we compared the original and back translated version for conceptual equivalence. After modification of ambiguous items were discussed and the scale was videotaped again until a consensus about the conceptual equivalence of test items was reached. 194 Deaf adolescents students completed the final Vocational Aptitude Test which was videotaped With KSL. Using the tests scores of participants in this study, researchers examined internal consistency, construct validity by exploratory factor analysis, convergence validity by correlations with school achievement, educational validity by feelings and attitudes after completing the test. The norms of the sub-scale were made because there were significant differences by gender and level of school. Using these procedures, researchers developed and standardized the Vocational Aptitude Test for the Deaf Adolescents(VATDA) with a Korean Sign Language Video. This test was constructed with 35 items which measures eighit sub-domain. The length of the final Vocational Aptitude Test which was videotaped was 28 minutes and thirty two seconds. The selectable jobs on basis of the result of the test was presented.
