The purpose of this study is to explore the impact of activities of schools on the motivation of students. Six determinants of motivation of students were identified and their impact was measured. High and higher secondary level schools were chosen as a sample of the study and responses were collected from different private and public sector schools of two cities viz., Sargodha and Rawalpindi. The variables used as determinants of motivation of students included the teacher?s performance, quality of education, discipline, infrastructure, facilities and extracurricular activities. The findings of research indicate that the school activities such as, the teacher?s performance, discipline, and infrastructure are critical factors to determine student?s motivation. Comparison is also made between the motivation of public and private sector school students, male and female students and between science and arts group students. Significant differences were found between motivation of public and private sector schools students and male and female students. While no significant differences were found between motivation of science and arts students.
