The official Myers-Briggs Type Indicator (MBTI) test can be taken online through the MBTI Online website. This website offers the official MBTI assessment and provides results that include your four-letter MBTI type. The cost for the online test is $59.95 and includes verification of your MBTI type via an interactive interpretation process designed by experts. Alternatively, the test is also available through certified practitioners who can provide in-person or virtual feedback discussions to help you interpret your results. Results from certified practitioners may vary in cost, but are often more expensive than the online option. It is important to note that the MBTI assessment is not a test, but rather a tool used to gain insight into your personality and preferences.
