Research Reveals that Personality-Major Match Strengthens Students’ College Success
By Lawrence Jones and Juliet Wehr Jones
According to Holland, “Different types require different environments. For instance, Realistic types flourish in Realistic environments because such an environment provides the opportunities and rewards a Realistic type needs. Holland calls this “congruence.” Incongruence occurs when a personality type lives in an environment that provides opportunities and rewards foreign to that person’s preferences and abilities – for instance, a Realistic type in Social environment” (Holland, 1997, p. 5). You likely use the concept of “congruence” in your career counseling work. Many do. It’s a sound idea and research supports it. “Personality-occupation fit” predicts career success and satisfaction (e.g., Kristof-Brown, Zimmerman & Johnson, 2005).
The degree of congruence or compatibility is defined by Holland’s hexagonal model.
And now, thanks primarily to scientists associated with ACT®, we know that the degree of “congruence” between students’ RIASEC personality and the RIASEC major chosen (what we call “personality-major match”), significantly affects:
The implications of this research are so important to the work of career counselors that this research and its application were recently highlighted in our two white papers (noted below).
Holland College Major Environments
When students choose a college major they are also choosing to interact with a particular academic environment. And, their interaction with it has a big impact on their performance.
As research shows, the environment of a major is created by the professors in it. For example, an Investigative major environment like Biology is created by professors who have a dominant Investigative personality. As the Holland’s theory predicts, they give greater importance to providing a basic understanding in mathematics and science, for example, than do their colleagues in the other five Holland environments. They also differ in the classroom strategies they use, their goals, and the importance given to examinations (Smart, Feldman & Ethington, 2000, 2006).
Personality, Environment, and College Performance
According to the Holland’s theory, “Behavior is determined by an interaction between personality and environment.” (Holland, 1997, p. 4). Research shows that the degree of compatibility or “congruence” between students’ personality and the environment (defined by Holland’s hexagonal model) affects grades, persistence, and graduation. For example,
1. Following 80,574 students in 87 colleges over a five-year period, Terrance Tracey and Steve Robbins found that good grades are related to having a major close to one’s interests/personality. Most impressively, they found that congruence predicted overall GPA after five years better than ACT Scores. (Tracey & Robbins, 2006).
2. ACT scientists Jeff Allen and Steve Robbins followed 47,914 students in 25 colleges and found students “more likely to flourish in academic environments that fit their personality types… Interests affect both choice of entering major and the likelihood of persisting in a major.” (Allen & Robbins, 2008).
3. A study of 3,072 students nationwide found that higher levels of congruence lead to a greater likelihood of attaining a degree in a “timely fashion” -- receiving a bachelor’s degree at the end of the fourth year in a four-year college and receiving an associate’s degree or certificate at the end of the second year in a two-year school (Allen & Robbins, 2010).
This impressive body of research has many implications for practice. Here are some of our recommendations:
1. Use a scientifically valid measure of Holland’s personality types (the research findings are based on this);
2. Use a comprehensive, up to date list of majors and programs of study that are scientifically classified according to the Holland environment types;
3. Help students learn and apply Holland’s Theory to their career and educational decisions;
