The purpose of this manual is to help Navy division officers, petty officers, and instructors build, use, and understand practical performance tests. Methods for testing men's ability to perform practical jobs are described in order to determine what they can actually do in meeting the requirements of their ratings, billets, or school training programs. Chapters are included on: (1) where and how to use performance tests advantageously, (2) deciding what to use for test tasks and an overview of the various types of performance tests, (3) "final product" performance tests, (4) "checklist" performance tests, (5) the construction and use of "examinee recorded" performance tests, and (6) how tests should be given and what to do with the test scores that have been obtained. The test construction chapters each contain an explanation of the type of test task to use, recording procedure, scoring methods, and suggestions on writing instructions for the examiner and examinees.
