The purposes of this study are to evaluate the development of disabled children us- ing LAP(Learning Accomplishment Profile) and to investigate the correlation between subtest scores of LAP. The development scores were obtained using 244 items in 5 su-btests (gross motor, fine motor, cognitive, language/cognitive, and self help) of LAP in 34 children with delayed development from February, 1998 to March, 1999. The birth history and risk factors for developmental disablilty such as prematurity, hyperbilirubi-nemia, low birth weight, and seizure were evaluated. Collected data were analized by Pearson's correla tion coefficient and Mann-Whitney U test. The results were as follow : 1) Among the subtests of LAP scores, fine motor, language/cognitive, and self-help were signi ficantly correlated with the cognitive subtests scores (p > 0.001) 2) On the other hand, gross motor subtest scores were independent to cognitive sub-test scores. 3) The children who had history of seizure during neonatal period showed significantly low scores in language-naming, fine motor-writing, and self help-eating. The LAP is considered as a useful tool to evaluate the cognitive development disab- led children. Cognitive function significantly influence on other developmental areas es-pecially on fine motor development.
