Interest Inventories to the RescueIn 1927 EK Strong, a psychologist, developed the first interest inventory, a tool used to measure individuals' interests and compare them to the interests of those working in various occupations. It was called the Strong Vocational Interest Blank. This tool has seen many revisions, and name changes, over the years. Now called the Strong Interest Inventory (SII), it remains one of the most popular self assessment tools in use today. There are others as well, including the Kuder Occupational Interest Survey, Self-Directed Search and the Campbell Interest and Skill Survey.
How to Take an Interest InventoryA career counselor or other career development professional can administer an interest inventory as part of a complete self assessment which should also look at things such as your personality type, skills and work values. You will be asked to complete a questionnaire containing a series of items about your likes and dislikes. These items may measure, for example, your interests regarding leisure activities, work-related activities, people with whom you prefer to work and school subjects. In order to get the most accurate results, it is important to respond to each item with as much honesty as possible. There are no right or wrong answers and no one will judge you.
When responding to items related to work-related activities, do not worry about whether or not you have training or a particular skill. For the purposes of completing an interest inventory, that is not important. All you are being asked at this point is whether that activity is of interest to you. There will be plenty of time later on, as you begin to explore your options, to decide whether or not you want to become skilled in a particular area.
Getting and Understanding Your Results
After completing an interest inventory, you will receive a report containing your results. The professional who administered the inventory should go over it with you and help you make sense of it. Your report should include a list of occupations that may be suitable for someone with your interests. Some of the occupations on the list may appeal to you while others will not. It is important to remember that just because an occupation shows up in the results of an interest inventory or other self assessment tool, that doesn't necessarily mean it's the best choice for you. It is imperative that you carefully explore any occupation you are considering regardless of what list it turns up on. Your interests may indicate that a particular occupation may be suitable for someone who shares your interests, but it may not be suitable for you for a variety of other reasons.
How to Discover Your Interests on the Cheap
If you want to try using an interest inventory on your own, you can take the Self-Directed Search (SDS). There is an online version published by PAR (Psychological Assessment Resources, Inc.) available for a small fee. After completing the assessment, you will receive a printable report containing a list of occupations that most closely match your interests. You can also try the O*Net Interest Profiler, a free online tool that can help you discover your interests.
