Career planning is a process in which personal skills, knowledge, and other criteria lead to job opportunities. Career development is establishing, developing, and setting a career direction. Success in either of these areas improves if you begin by establishing criteria. A criterion is a standard or principle for judging, evaluating, or selecting something. Having criteria points you in a direction that allows you to make informed choices and wise decisions. You want to work with someone who understands these differences and can guide you seamlessly between planning a career and conducting a job search.
