Document Summary

Test development can be broken down into three distinct stages. Issues such as writing, scale construction, response sets, and section of test format. Next, new tests are standardized for use on particular target populations, norms are developed, o and considerable research is undertaken to establish estimates of the tests reliability and validity. Finally, tests need to be revised to keep them contemporary. The first and most fundamental decision faced by test developers is what type of items they should use. Recently, items that require a constructed response like essay questions have been given more attention. Test developers often face the choice between a format that requires test takers to produce or construct a response, and one that requires them to choose or recognize a correct response in a highly structured format. Advocates of constructed response methods argue that these tests measure a wider and richer array of human abilities compared to multiple choice.
