The study investigated the effects of thematic approach on communication skills for preschool children. The study was a quasi experimental non-equivalent pretest-post-test control group design whereby 5-6 year old preschool children (n = 49) were randomly assigned to an experimental and a control group. The experimental group students were exposed with thematic approach of teaching and the control group with the traditional approach of teaching. Comprehensive Communication Assessment 5-6 yr (CCA) was used to measure the communication skill of UKG children. Analysis of covariance (ANCOVA) was used to analyze the data. The results reveal that there was a significant difference between the thematic approach group and the traditional skill approach group students on post test score (F (1, 46) = 7.959, p < 0.05). The findings of this study suggested the importance of thematic approach to improve communication skills in early preschools.
