About Tests & Measures

  • Where can I find a copy of the test?
  • What validated instruments are available to measure?
  • What are examples of studies using these tests?

The aim of this guide is to help you locate unpublished tests and commercial tests and find information about the validity of tests.

Tests and measuring instruments are an important part of research and practice in the fields of psychology, education, health, and social work. They are used for diagnosing, researching, and assessing. They can be questionnaires, assessments, interviews, ratings, inventories, scales, measurements, surveys, measures, and tests. Instruments are either published or unpublished. They can be found in books, journal articles, and on the Internet.


Published tests are owned by and available through commercial publishers. The library does not carry copies of most of these tests because most publishers do not sell them to libraries. These tests need to be purchased directly from the publisher, and often require the buyer to have certain credentials of authority. The library has a small collection of commercial tests which may be used for educational purposes.


Unpublished tests can be available online and in print. They are not tests that you get from the publisher. Unpublished tests appear in journal articles, books, and dissertations.

Locating information on a specific test or searching for an instrument related to a specific issue or topic often requires searching through a variety or print and online resources.
