Do Personality Tests Pass the ADA-Compliance Test?

The ABA Journal (hat tip: Overlawyered) is reporting that the EEOC is investigating whether several well-known companies are violating the ADA by using pre-employment personality tests to screen applicants.

I cautioned employers about this issue three years ago. This is what I said:

Despite the apparent prevalence of these types of tests, there is very little guidance available on their legality. Karraker v. Rent-A-Center (7th Cir. 2005) is the seminal case. As Karraker points out, the legality of a personality test by an employer hinges on whether it qualifies as a “medical examination” protected under the ADA. 

The Karraker court concluded that the ADA covered the MMPI personality test as a protected medical exam. In reaching its decision, the court drew a key distinction between psychological tests that are designed to identify a mental disorder or impairment (medical examinations), and psychological tests that measure personality traits such as honesty, preferences, and habits (not medical examinations). Because the MMPI revealed, in part, potential medical diagnoses such as paranoid personality disorder, the court concluded that it was a protected medical examination. Other personality tests may not dictate the same result, depending on the types of results provided.
