On November 27, 2008, one of our best known, influential and respected vocational psychologists, Dr. John L. Holland, died in Baltimore, Maryland. (photo courtesy of American Psychological Association) We are particularly sad to hear of Dr. Holland’s passing. The Career Key and The Self-Employment Key tests, as well as versions of The Career Key test adapted for use in different countries, are scientifically valid measures of the 6 personality types of Holland’s Theory of Career Choice. Dr. Holland's contributions have helped and will continue to help millions of people through our website, our licensees, as well as through other scientifically valid assessments based on his work.
In 2008, Dr. Holland received the Award of Distinguished Scientific Applications of Psychology from the American Psychological Association, “presented to a person … who has made distinguished theoretical or empirical advances leading to the understanding or amelioration of important practical problems.”
According to the November 2008 issue of the American Psychologist magazine, the award citation reads:
“For outstanding contributions to vocational psychology and personality. John L. Holland’s hexagonal theory of vocational interests and his research have shown the importance of vocational environment and vocational personality interactions. His research shows that personalities seek out and flourish in career environments they fit and that jobs and career environments are classifiable by the personalities that flourish in them.To read the complete citation and biography, please visit the NCDA website page here.
Further, he was a pioneer in work on assessments of university environments and their influence on students and in the development of knowledge about nonacademic accomplishments. He also contributed significantly to research on originality and interpersonal competence. With wit, wisdom, and intellectual prowess, he has for five decades influenced and inspired students, colleagues, and practitioners of applied psychology.” [Emphasis added]
To truly realize the benefits of Holland's Theory and respect his work, it is important for people using career tests to choose ones that are scientifically valid measures. Unfortunately, most online career tests on the Internet are invalid and can harm you. If you are not sure whether a career test is valid, visit our website or please read this short article.
