The purpose of this Guide to Good Practices is to provide direction to training personnel in
the broad areas of design, development, and implementation of examinations.
Nuclear facilities spend a significant amount of training resources testing trainees. Tests
are used for employee selection, qualification, requalification, certification and recertification,
and promotion. Ineffective testing procedures, or inappropriate interpretation of test results,
can have significant effects on both human performance and facility operations. Test
development requires unique skills, and as with any skill, training and experience are
needed to develop the skills. Test development, test use, test result interpretation, and test
refinement, like all other aspects of the systematic approach to training, should be part of an
ongoing, systematic process.
For some users this document will provide a review of ideas and principles with which they
are already familiar; for others it will present new concepts. While not intended to provide
in-depth coverage of test theory design and development, it should provide developers,
instructors, and evaluators with a foundation on which to develop sound examinations.
