The core is a 3 dimensional space with muscular boundaries diaphagram superior, abdominal and oblique muscles (anterior –lateral) paraspinal ,gluteal muscles posterior and pelvic floor muscle ,hip girdle muscle inferior. The inherent nature of these muscle boundaries produces a corset like stabilization. Core stabilization is the integration of the passive spinal column, active spinal muscles and the neural control unit, which when combined maintains the intervertebral range of motion within safe limit to enable activities to be carried out during daily living. 1 Aim of Study- To study comparison between core muscle endurance and dynamic stability among government and private school going children. Methodology:- This is a comparative study and total 200 subject taken. Purpose and procedure of the study was explained to all the subjects. Subjects were divided into two groups – group 1 –government school going children’s. Group 2- private school going children’s Both groups subjects were assessed for core muscle endurance and dynamic stability. Conclusion:- On the basics of above results, it can be concluded that government school children were better than private children on variables core muscle endurance and dynamic stability
