Tests and measures are often broken up into two categories:

• Non-commercial ("unpublished")- instruments usually found in books, journal articles, dissertations, etc. While most do not require purchase, they may still be protected by copyright law. Researchers should seek permission for use unless permission has been explicitly granted.
• Commercial ("published")- instruments usually licensed for use by a specific publisher and require purchase. Beware of unauthorized versions on the Internet.

View Webster University's Institutional Review Board to make sure all required procedures and policies are followed when using tests in your research.

Databases are a good source for finding information about tests in a particular subject areas like business, nursing, counseling, and education. Listed below are some helpful databases for finding tests as well as a link to the Library's comprehensive list of databases.

Some databases have special fields set aside for recording tests used in a study. You may search the field by entering either the name of a test or the topic the test is about. View examples of how to search for specific tests on this page.
