Become Certified to Administer the MBTI® Tool

The MBTI® instrument is a restricted assessment tool and requires specific qualifications in order to administer it to others. A practitioner must be trained in the use and interpretation of the instrument either through previous academic study or by taking courses designed specifically to meet MBTI certification guidelines. In addition to ensuring the ethical and accurate use of the Indicator, such training also provides the practitioner with methods and knowledge for assisting clients in understanding MBTI results and for using that information in various aspects of the clients' lives.

There are several versions of the MBTI instrument. The MBTI® Certification Program prepares practitioners to use and purchase the MBTI® Step I™ and Step II™ instruments. The MBTI® Step III™ Certification Program prepares practitioners to use and purchase the MBTI® Step III™ instrument.

The Myers & Briggs Foundation is the exclusive provider of the public MBTI® Certification Program in the USA.
