The relationship between levels of shyness among the adolescents (13-18 years) of public and private schools were investigated in the present study. 120 students studying in different grades from public and private schools in Islamabad (Pakistan) were selected by Random sampling technique. It was hypothesized that levels of shyness among the adolescents of private and public school is different. To measure the levels of shyness, the McCroskey Shyness scale was administered on the sample. Data was analyzed by applying t-test for independent samples and hypothesis was not supported because there is no significant difference found between levels of shyness among the public and private schools adolescents. The research presents evidence that there is no impact of schooling system on shyness levels of adolescents but shy adolescents are less likely to participate in communication and classroom activities or ask questions when they need help with schoolwork. They greatly suffer from social anxiety.
