"A research instrument is a testing device for measuring a given phenomenon, such as a paper and pencil test, a questionnaire, an interview, a research tool, or a set of guidelines for observation."

What is the difference between a "published" and an "unpublished" test/research instrument?

• Published tests are tests which may be purchased from a commercial test publisher. Sometimes special training is required to administer commercial tests. Standard copyright restrictions apply.
• Unpublished tests are tests which are published by an individual author or small group of authors, often in a journal article or book chapter. Copyright restrictions may apply to such tests.
