What are tests and measures?

" the methodology that deals with designs, administrations, and interpretations of measurement on individuals’ constructs such as abilities, attitudes, personality, knowledge..." Tests & measures are the instruments, surveys, questionnaires and more designed to assess these constructs.

Quote by Hua-Hua Chang in theInternational Encyclopedia of the Social Sciences. Ed. William A. Darity, Jr.. 2nd ed. Detroit: Macmillan Reference USA, 2008. p587-590.

Unpublished vs. Commercial Tests & Measures

Tests are either commercial or unpublished.

  • Unpublished/Noncommercial Tests:  The instrument has been developed more for research purposes and is not sold by a commercial test publisher.  The test author might choose to include the full text of the instrument in a journal article or dissertation, or might give persmission for the instrument to be reprinted in a book.  It can be more difficult to find these. See the box below labeled Unpublished tests & measures for details on how to identify and locate unpublished tests and measures.
  • Commercial/Published Tests: The intstrument is published by a commercial test publisher.  These tests must be purchased from the test publisher, so you will seldom, if ever, find the items from these instruments in the public domain.  Additionally, only qualified persons are allowed to buy these tests.  See the box below labeled Commercial tests & measures for details on how to identify and locate commercial tests and measures.


See the American Psychological Association's (APA) FAQ on how to find published and unpublished psychological tests.
