Present study aimed to study the effect of Positive Psychology Intervention on Psychological Wellbeing of teachers classified into experimental and control groups. It is an experimental study in which 2 groups were formed with 15 males and 15 females in each group. The experimental group subjects received the Positive Psychology Intervention for 2 weeks. The PPI included diary writing about gratitude and altruistic behaviour on daily basis and writing positive statements about self. Pre and post test assessment of both the groups was done for PWB levels. Mean, SD and t test was calculated to study the objective. When the pre and post test data of Experimental Group was compared, the t value obtained was 7.49613 which is significant intervention at 0.05 levels. This implies that there is a positive impact of Positive Psychology Intervention on Psychological Well- Being of the teachers.
