Using the ECLS-K national database, this study compared the self-concepts in reading, math, general academic (all-subjects), and peer areas for third-grade students with and without identified learning disabilities. Unlike most similar research on academic self-concept, students’ measured achievement in reading and math was controlled, thereby effectively comparing students at similar levels of achievement. Correlations between achievement and self-concept were small for both LD and non-LD groups. When controlling for achievement, academic self-concepts were not lower for the students with LD. Similar to other studies, students with LD tended to statistically over-predict their achievement compared to the non-LD group. This study extends the Strein and Signor (2005) study that used similar methodology on a national database of high school sophomores.
