This database, produced by the American Psychological Association, contains the full-text of 10,000 tests, surveys, and other measures. It covers a wide variety of topics in psychology, counseling, social work, education, rehabilitation, and health related areas. Although many of these instruments originally appeared in journal articles, they are considered "unpublished" because they have not been published by commercial test publishers. As a result, these instruments carry only minimal copyright restrictions, making them ideal for class assignments and similar projects. For dissertations and other advanced research, the standard catalog of measurement instruments available from commercial publishers should also be consulted.
