When you complete the Career Key, you will be assigned Holland Codes, which assess people's personality types. These codes are often used by career counselors for matching students up with jobs which they will, according to their personality type(s), find most satisfying. The area in which you received the highest score is the Interest Area in which you should look for jobs first, but most people are a combination of types, so you might also want to look into your second and third highest rated Interest Areas.
