School heads always dispense their supervisory functions to teachers. The teachers are generally satisfied with their job and have very satisfactory level of work performance. The school heads’ supervisory approaches and extent of supervisory practices did not relate with the job satisfaction and work performance of teachers. In conclusion, the school heads supervisory approaches and practices have no bearing on teachers’ work performance and on the teachers’ job satisfaction.
