This study examined the differences of elementary students’ social support from their peer, family, and teachers according to their sex, disability, and school grade. The subjects were consisted of 220 elementary school students in Daegu. Data obtained by questionnaire survey were analysed. The results of this study were shown as follows: First, no significant difference between male students and female students was shown in their perceived social support. Second, significant difference was shown between normal students and LD students. The level of perceived social support was higher in normal students than students with LD. Family support was highest in both groups, while peer support was lowest in LD group. Third, total social support was highest in 6th grade, but lowest in 5th grade. Significant difference was shown in teacher support which 4th grade was higher than 5th grade. Family support was highest regardless of students’ variables, however some difference was shown in peer support and teacher support according to students’ variables. The implications were discussed and the suggestions were made for further studies.
