The application of a PERT system to a large-scale project will increase the probability of accomplishing project objectives by providing greater visibility of (1) the project objectives, (2) the relationships among the parts of the projects, and (3) the relationships of those component parts to the project objectives. Consequently, educational researchers should find that a PERT system will increase their collective ability to coordinate planning and evaluation efforts. A review of a PERT system applied to a study of disadvantaged school children indicates that in order to achieve optimal utility, the system should be implemented well ahead of the project starting time, and must be responsive to program developments through continued updating procedures.
