An interest inventory is a self-report questionnaire that is used to assess an individual's preferences and interests and how these relate to the working world and career goals. This inventory identifies likes/dislikes along with what types of activities are preferred. These questions can also identify what methods and what types of work (solitary vs. group, for example) that individuals likes to do. It is composed of 75 questions that were normed on a sample of 739 individuals who are in careers that they feel satisfied with. This self-assessment can be given by a counselor or a career consultant. There are no right or wrong answers to the questions, they are intended to identify preferences and interests. Typically people who share the same occupation share many of the same interests so by identifying these interests you can possibly determine what type of field a person would be suited for.
