Supervision is a very important process stage for an organization in supervising and controlling the implementation of planned programs in order to achieve the stated goals. Supervision needs to be done on the basis of improvements that must be made to existing human, material, and financial resources. In order to implement a plan or program so that good results are achieved, one way is to carry out continuous and consistent supervision. Through supervision, a supervisor can make predictions and evaluations as early as possible on things that become obstacles in carrying out a work program, so that the supervisor can take strategic action which is a solution to these obstacles. In addition, supervisors can also analyse various facilities and advantages in schools which will be potential factors to be developed and can improve vocational schools at that time and in the future. So that in the end all elements in the school can carry out their work according to established procedures and can achieve the goals of implementing education in schools effectively.
