The present study was designed to assess the Problem Solving Ability of Secondary School Students in relation to Scientific Interest and Social Maturity. A sample of 100 students studying in class IX was selected from one of the Government Model Senior Secondary Schools of Chandigarh Administration. Problem Solving Ability Test by Dubey (2010) was used to assess the Problem Solving Ability of the students, Scientific Interest Inventory by Misra (2012) was used to assess the Scientific Interest of the students and Social Maturity Scale by Rao (2009) was used to assess the Social Maturity of the students. Appropriate statistical tools were employed to analyze the results. Results of the study revealed that there is no significant relationship between Problem Solving Ability and Scientific Interest (r= .128) and Problem Solving Ability and Social Maturity (r= .161), leading to the inference that both the null hypotheses cannot be rejected as per this study.
