I don’t think that there is any particular “next step” – all you have right now is a test that indicates that your daughter can potentially do well in many endeavors. She should let her own interests be her guide. If she is at a loss --has no clue what she wants to do or what sort of major she wants – there’s no hurry, most colleges don’t require students to declare a major until after the first or second year. Encourage your daughter to get involved in volunteer activities, or to get a part-time job or summer internship to explore various types of work environments-- that might help her get a better sense of things.
??? This statement kind of sounds like something you might have picked up from the promotional material of the testing outfit. What’s “many”? There are all sorts of things that go into career satisfaction, but “utilize all their major aptitudes” is kind of silly for someone with a broad range of aptitudes. Keep in mind that many people who are also multi-talented enjoy new challenges as well – so some might seek stimulation and feel very much rewarded by taking on work or education in areas where they did not test particularly well. That would be particularly important for a young person who is still growing and has much to learn about herself. Use the test as simply one more piece of information – but don’t let your daughter be defined by the test, or think that she must somehow fulfill or live up to some sort of ideal potential suggested by positive test results.
