Type Coaching and Training

Mary McCaulley was born in New York in 1920. She lived elsewhere in the US before completing a degree in languages (Spanish, Latin and Greek), which she taught briefly in high school.

After serving on the home front in World War II, Mary returned to study counselling. She later worked in an insurance company as a job analyst before returning to study, completing first a Masters, and then a Doctorate in Psychology in 1964.

Subsequently Mary taught at the University of Florida (Gainesville), where she ran courses and programs on the psychology of women and human sexuality in general. It was while doing this work that she came upon the MBTI.

Her research with the MBTI stimulated her to write to Isabel Briggs Myers, whom she met in August 1969. Isabel invited Mary to work with her, teaching her about her insights into type, and they did so until Isabel's death in 1980. Together they founded the Typology Laboratory at the University of Florida, and developed a computer scoring program for the MBTI.

Mary initiated the discussions that resulted in Consulting Psychologists Press undertaking to publish the MBTI in 1975. That year also saw the first conference on the MBTI, and the establishment of the Typology Laboratory as an independent entity - the Center for Applications of Psychological Type (CAPT), of which she is still President.

CAPT was instrumental in the founding of the Association for Psychological Type in 1979. Mary also established MBTI News, now continuing as the Bulletin of Psychological Type, to which she is still a regular contributor. More significantly, she co-authored the revised MBTI Manual, published in 1985, and contributed to the latest (third) edition.

CAPT has a long-standing role as a research and training body, and Mary was a significant influence in the development of training programs on type, notably Qualifying programs. She has written many articles on type and counselling, careers, education and leadership; she is also the co-author of the Atlas of Type Tables (1986). CAPT holds biennial conferences on the MBTI in Education, on leadership, multicultural issues and therapeutic applications, as well as general MBTI research.

Mary visited Australia in 1994 for AAPT's Melbourne Conference.

Her immense knowledge of type, her insights into its many applications and interpretations, combined with her experience of working with Isabel Briggs Myers are unique in the type community. Mary continues to contribute to the understanding of differences through her presentations and writing.
