The results of the MBTI® instrument are always confidential and are not to be shared with others unless the respondent chooses to do so. People take the MBTI instrument in order to understand and manage their own personality preferences better. If results were not confidential, people might not answer honestly and the results would not be helpful.
Be sure the person and the organization that administer the instrument to you intend to keep the results confidential. If that is not the case, find another administrator. If your employer insists on seeing the results, refer him or her to the link about ethical uses of the MBTI instrument.
