The study examined principals’ performance of internal supervision of instructions in public secondary schools in Ebonyi State. Principals’ internal supervision was delimited to classroom supervision of instruction, monitoring students’ achievement, instructional materials and staff development. Two research questions and four hypotheses guided the study. The study adopted the descriptive survey research design. A sample of 605 out of 1640 teachers was drawn using stratified proportionate sampling techniques across urban and rural teachers. A questionnaire titled ‘principals’ performance of supervision of instruction questionnaire’ was used as the instrument. The data collected were analyzed using mean scores, standard deviation and t-test statistics to test the hypotheses at 0.05 alpha levels. The findings showed a significant positive difference between urban and rural teachers on principals’ performance of supervisory functions. The study recommended regular internal supervision of instruction since it encourages wider coverage of the curriculum and reduces incidences of examination malpractices by students
