This guide is designed to offer a set of resources to assist in identifying and finding tests, measurements, assessments, rating scales on particular subjects as well as resources for further information on testing in general. For information about preparing for tests, see the Test Preparation section.
There are two main categories of tests:
1) "Published" tests are those published commercially by a test publisher. These are typically only available directly from the publisher, often come in the form of kits or multiple booklet packets, and can be costly.
2) "Unpublished" tests are those that may have been published in journals or other books but have not been published by a commercial test publisher. These are free to access if you have the journal or book in which they appear.
