Tests and assessment measures can be difficult to identify and access. Test instruments by commercial publishers or by individual authors are fairly easy to identify and locate. In most cases users are required to obtain a copy of the instrument or obtain permission to administer it.
Unpublished tests can often be very difficult to locate.
Sometimes they are available directly from the author or they have been included as a part of a book, dissertation, journal article, or research report. To administer an unpublished instrument, the user must be aware of possible copyright restrictions. Permission of the author is often required. A limited number of commercial tests are acquired for the collection with access to them highly restricted. The Library, in consultation with faculty, has formulated a policy regarding the test collection.
