DISC Assessment Test

This is an interactive version of the Open DISC Assessment Test.


DISC is a pop-psych personality system based around four personality types. The DISC system is mostly used with an employment or team building focus. The roots of DISC was a book published in 1928, titled Emotions of Normal People. In it, William Marston theorized that a person would express their emotions in one of four ways, from which come the four letters D I S C. He did not intend to make an assessment, though, and modern DISC does not have all that much in common with Marston's work. In the 1950s a series of industrial psychologists separately used his theory as the basis of a tool for employee selection and organization. Today there are many tests that exist under the name DISC, marketed by various psychological consulting companies for use by human resources departments, each with their own differences. There has been no work using a DISC model in academic psychology since the first work on DISC in the 1950s.

The ODAT was created by this website as a free and open-source tool to match users to a DISC type. The documentation of its development can be found here.


The test has 16 statements of opinion that you must rate on a five point scale of how much you agree with each. It should take most people 4-6 minutes to complete.


This test is provided for educational use only. It should not be used as psychological advice of any kind and comes without any guarantee of accuracy or fitness for any particular purpose. Also, your responses may be recorded and anonymously used for research or otherwise distributed.
