One of 33 self-paced instructional modules for training industry services leaders to provide guidance in the performance of manpower services by public agencies to new or expanding private industries, this module contains three sequential learning activities on developing performance tests for industry services programs. The first learning activity is designed to provide the learner with the needed background information on developing performance tests (criterion referenced tests) for job training based on performance objectives. The second learning activity gives opportunity to apply the information in a practice situation, and the final checkout activity allows the learner to develop performance tests in a real work situation, such as when employed or when serving as an intern learner. Feedback devices (learner self-test and performance checklist) are included for use by the learner and instructor/supervisor to assess progress. Case study information, sample performance objectives, sample performance test, process evaluation checklist, and an end product evaluation checklist are appended for guidance in performing the learning activities. (This module is the fourth of seven on preparing training materials.) (JT)
