My forty years of study in personality type is in Briggs-Myers personality assessment. Career placement tests and employment placement tests are Briggs-Myers tests. I have used their insights in tutoring children with learning disabilities and in employment counseling. I have taught community education courses and given counseling on these topics.
I have posted my teaching materials on this blog, and other articles I have written on Personality Type. Hope you enjoy them. Feel free to post questions. It keeps me writing and learning.
