Present study examines different teaching styles, measures adolescents’ psychosocial development and investigates the relationship of teaching styles and adolescents’’ developmental tasks. A total of 130 students and 45 teachers from three Intermediate Colleges of Rawalpindi region were taken as sample of the study. Two instruments namely TSQ & SPSDI were constructed at 5 point Likert scale and validated through two experts of the field. Their reliability was checked through SPSS at Cronbach’s Alpha and it was found to be .85 & .76 respectively. TSQ indicated that most of the teachers were aware of their teaching style and these styles were given five categories namely; expert, formal authority, personal model, facilitator & delegator style. The teachers having personal model style have a strong positive correlation with adolescents’ psychosocial development whereas expert style has negative correlation.
