The study determined how the leadership role of secondary school principals of Karachi would
influence on students academic achievement? The study used two major hypotheses related to
demographic variables, for example status of school and professional qualification of principals. The
population was large and diverse, therefore, stratified random sampling design was adopted for the
study. The total size of the sample was 90 principals and 360 students from 90 government and
private secondary schools of Karachi. The researcher selected 15 schools from each district i.e,
15*6=90. A questionnaire and an interview protocol were used as research instruments. The
collected data was analyzed through percentage and ‘t’ test. Private and trained secondary school
principals were found more effective as compared to government and untrained secondary school
principals in respect of academic achievement of students
