This study aimed to examine to what extent academic achievements, learning disorders, behavior problems and loneliness explain the variance of students' social skills. The differences between students diagnosed with learning disorders and students without learning disorders in all four variables were examined. Participants were 733 elementary students (642 without LD; 91 with LD). Homeroom teachers assessed students' academic achievements, behavior problems, and social skills. Students completed questionnaires regarding their loneliness feelings. Regression analysis showed that academic achievement and behavior problems explained approximately 70% of the students' social skills variance, whereas LD did not, and loneliness explained social skills variance only among boys. These unexpected but encouraging findings are discussed in terms of the positive process of change that occurred since the announcement of the Israeli National Special Education Law of 1988, which made it possible for students with LD to be integrated in regular classes.
