Personnel Simulation (PERSIM), a computerized model developed to trace the flow of faculty through the processes of entry into, engagement within, and withdrawal from an education agency, is described. Major topics discussed include: 1) PERSIM's capabilities; 2) the development of a data base for the model; 3) the integration of PERSIM's components; 4) factors affecting the selection of data base elements; 5) PERSIM's extension of the Markov Chain Concept; and 6) the model's generator feature. Following this, some test cases are defined and the results thereof presented. Lastly, applications of PERSIM for activities such as the evaluation of teacher contracts and proposed legislation, the projection of manpower estimates, the prediction of hiring requirements, and the analysis of terminations are described.
