Generate a list of your main personality traits. Use emotional descriptors such as "gregarious," "pensive," "aggressive," "fantasy-prone" and the like. This list will serve as a jumping-off point for developing a more complete personality report.
Take a personality test online. Numerous free diagnostic tests are available on the web. These tests offer a methodical way of articulating your personality type and character attributes and may suggest personality traits of which you were otherwise unaware. Ideally, take several tests for more comprehensive results.
Compare yourself to the "personality scales." According to the Sage Handbook of Personality Theory and Assessment, different personalities are comprised of a combined manifestation of scales, including rule-consciousness, emotional stability, abstractedness, self-reliance, vigilance, liveliness and sensitivity. Note that these are not personality traits per se, but structures from which traits can emerge, depending on the individual.
Synthesize the data into a descriptive profile enumerating and explaining the various aspects of your personality. This can be written in first or third person. Emphasize the aspects of your personality as it relates to the college experience.
Write about your likes, dislikes, hopes, fears and expectations of college. Describe in detail things that are pleasing to you and things you prefer to avoid to develop a fuller picture of the kind of person you are and tastes you have. Combine emotional descriptors with concrete facts about your personality.
Write enough to provide a comprehensive picture of your character without being excessively wordy. The specific length will depend on the particular requirements of the college for which you are filling out the profile.
