In the world of assessment the words "published" and "unpublished" have a special meaning.
-Published tests are those available from commercial publishers.
-Use of published tests is highly restricted.
-In most cases users are required to contact the publisher or author of a test instrument to obtain a copy of the test or to obtain permission to use the test.
-Unpublished tests are not commercially available.
-Tests that are not sold commercially can be difficult to locate.
-Obtain a copy from the individual author, either directly, or printed as part of a book, article or research report.
-Tests found in this way can be incorporated into academic reports such as term papers, provided proper credit is given.
-Administering an unpublished test requires dealing with possible copyright restrictions. Contact the author for permission.
