How many practicing psychologists are there in the United States?
How do I find a psychologist in my area?
The Psychologist Locator in the APA Help Center is a helpful resource.
Where can I find more information about psychological tests?

Start by searching PsycINFO to find the names of tests that have been used in research and written about in the literature. Test names appear in both the Abstract field and the Tests & Measures field. If the document includes the actual test in its entirety, it is marked "Appended" in the Tests & Measures field.

APA's Science Directorate is a good source for general information about psychological tests and test publishers. Visit their Testing and Assessment page, which includes a link to frequently asked questions about tests.

Another good source for test information is the Buros Institute Test Reviews Online.

The APA Science Directorate answers hundreds of calls and e-mails each year from persons trying to locate the right test or find more information about psychological tests. APA neither sells nor endorses testing instruments, but it does provide guidance in using available resources to find psychological tests.

Can psychologists prescribe medications for their patients?
As of 2016, properly trained and qualified, licensed psychologists in New Mexico, Louisiana, Illinois and Iowa are authorized to prescribe certain medications for the treatment of mental health disorders. In addition, there are many efforts within the field to expand this authority.
