Finding tests using databases is not easy or intuitive. Follow these steps for each of these databases, but if you need help, please do not hesitate to contact a reference librarian.
You can use ERIC to find information about tests. Sometimes you can retrieve articles containing a copy of the test or measurement instrument itself.
(NOTE: TESTLINK IS NOT FULLY FUNCTIONAL ON SUNDAYS WHILE ETS UPLOADS NEW INFORMATION INTO THE DATABASE)
You can use PsycINFO to find information about tests and perhaps the tests themselves.
