This guide will help you locate information about tests and how to find the tests themselves. Generally, commercially available instruments must be purchased from publishers. Tests that are not commercially available may be found in books, journal articles, printed reports, or may be available from the author. Students may wish to speak with their advisor as they or the research group with which they are affiliated may have a copy of a test. In some cases, publishers will provide copies of tests for research purposes. This generally involves writing a letter to them explaining the purpose of your inquiry. An address for a test publisher can be found in a variety of references, such as: Mental Measurements Yearbook (online version). In some cases, the only way to procure a test is to contact the author of the instrument.
