The official MBTI® is not free. Unless you can take it through school or work, you will typically have to pay a fee to take the true MBTI assessment. This is because the MBTI must be delivered by a qualified consultant, who should be paid for their services. Also, the publishers of the MBTI assessment collect a licensing fee each time the assessment is used, to fund continued research and development of the instrument.

You can take many free online quizzes that claim to measure your Myers Briggs personality type. Some of these are really quite inaccurate despite being extremely popular. For example, we have found that one of the most popular free quizzes consistently biases results toward the Feeling and Judging dimensions. Taking such quizzes can be quite misleading and frustrating for people attempting to discover their true personality type.

For people who are hoping to use their Myers Briggs personality type information to make serious decisions, such as choosing a career, we recommend taking the official MBTI and taking advantage of the services of your test administrator to verify your type. Even the official MBTI has about a 25% margin of error in determining your correct personality type, so going through this verification process with an expert is important.

If you are interested in learning more about personality type but are not ready to pay for an assessment, we can recommend this personality type questionnaire. Of the free quizzes we have tested, we have found it to be the most accurate.
