An Experimental study was conducted on Self-Esteem before and after Teacher-Child-Parent-Program among school children in selected schools at Kannyakumari District. Two groups Pre-test Post-test Control group design was used in this study. The researcher screened 749 school children, among that 122 were having low Self-Esteem (16.3%). Sample size consists of 58 children in Experimental groups and 58 in Control group and there were six drops out. Teacher-Child-Parent-Program was administered to the teachers and parent separately for the Experimental group. For students Self-Report gaming and Positive Reinforcement gaming was given. Posttest was done after 8 weeks of intervention Dr. Ken Williams (2000) Brief Self-Esteem Inventory was used to assess the level of Self-Esteem. Objectives of the study are: (i) To compare the Pretest and Posttest Self-Esteem among school children in Experimental group; (ii) To compare the mean difference in Self-Esteem between school Children in Experimental and Control group and (iii) To find the association between mean difference in Self-Esteem and the selected background variables among school children in Experimental group. The data gathered was analyzed by descriptive and inferential statistics. The conceptual framework used in the study was based on Imogene King’s Goal Attainment theory. The Post-test mean Self-Esteem among school children in Experimental group 64.71 was significantly high; t = -5.71 (P<0.001). The mean difference between Experimental group was 9.91; Control group was 3.76; were SD was 13.234 and 9.701 respectively; were t = 2.857 (P<0.05). This showed the Teacher-Child-Parent-Program was effective among the Experimental group. Regarding association, there was a significant association between Relationship with parents and Cell phone usage was significantly influence the Self-Esteem among School Children
