Personality Inventories
Many personality inventories used in career planning are based on a theory by psychologist Carl Jung. Jung divided people into eight personality types — extroverts, introverts, thinking, feeling, sensing, intuitive, judging, and perceptive. Career counselors often use results from tests based on Jungian Personality Theory to help clients choose careers. Career counselors contend that those of a particular personality type are better suited to certain careers. An obvious example would be that an introvert would not do well in a career that requires public speaking. However, a personality inventory alone shouldn't be used to predict whether you would succeed in a particular career. It should be used in conjunction with other inventories, such as those that look at interests and values.Career development practitioners frequently administer the Myers-Briggs Type Indicator (MBTI) for the assessment of personality. It measures differences in traits between individuals. It looks at how one energizes (Extroversion vs. Introversion), perceives information (Sensing vs. iNtuition), makes decisions (Thinking vs. Feeling), and demonstrates his or her lifestyle (Judging vs. Perceiving). When the test is scored, the individual is given a four letter code, i.e. ENFJ (Extroversion Intuitive Feeling Judging), indicating his or her preferences. Each preference is also assigned a number to show how strong that preference is.
Skills Assessment
When deciding what field to enter, you need to determine what skills you have. You should look at what you're good at, as well as what you enjoy doing. You may be very adept at a particular skill, but despise every second you spend using it. Generally speaking, though, you usually enjoy what you do well.While you're assessing your skills, you should also consider the time you are willing to spend on acquiring more advanced or new skills. A question you could ask yourself is this — if a career holds all the qualities I find appealing but it takes X years to prepare for it, would I be willing and able to make this time commitment?
