Note: Test databases will give you information about a test and lead you to the author or owner of a test instrument.  They do not always contain full-text test instruments. 

Unpublished tests are non-commercial (not for profit) and can often be found by searching journal databases. Here are the most commonly used databases:

• A commercial test is owned and available through commercial publishers or organizations for a fee.  Researchers who want to use it must purchase the instrument and scoring guide from the publisher. Permission to administer is granted with purchase.

• An non-commercial test is one that is not sold through a commercial test publisher, but is typically available in the research literature. The instruments are often available for free use, often published as an appendix with the research in a journal article, dissertation, or other research-based literature. It takes some digging to find a test in full and you must ensure you have permissions from the author before administering.
