Types of Tests & Measurements

Tests and measures are used for diagnosing, researching, and assessing phenomena in the social and behavioral sciences, education, health, and other areas. They may be published or unpublished.


Published tests are instruments commercially published by a test publisher. They are administered and scored in a consistent manner. The validity and reliability of the instrument are two essential elements for defining the standard quality of the test. These tests are generally only available from the publisher and often come in the form of kits or booklets. They can be very costly.


Unpublished tests are instruments that have been published in books or journals but have not been published by a test publishing company. Using an unpublished test may come with additional ethical responsibilities on the part of the researcher including contacting the author and requesting permission to use the test. In addition, if the material is copyrighted, permission to use the test must be made in writing.

Search Strategies for Tests & Measurements

To find published tests, open the Mental Measurements Yearbook with Tests in Print database. It is found in the Recommended Tests & Measurements Databases list above or by going to the A-Z Database List

A list of tests indexed in MMY is located at the Buros Center for Testing website.

When the database opens, search the name of the test and then click its title in the list of results. You will see a page with information about the test, including a section for Publisher Information. Contact the publisher for information about purchasing.

The record also includes other information about the instrument such as author, purpose, population, time, etc. Click the HTML Full Text link or scroll down below the indexing information to read a review of the test.

Finding unpublished tests is not as cut and dry as there are many more places they may be found such as in specialized databases (PsycTESTS, Health and Psychosocial Instruments), subject databases (ProQuest Dissertations and Theses Global, PsycINFO, etc.), books, articles, and other resources.
