Designed to keep health care workers up-to-date on medical advances, continuing education (CE) credits are an educational requirement for professionals with health care careers. They fill the gap between current care and optimal care and are mandated by licensing boards, professional societies and certification boards for health care professionals. The human services professional is an individual who is driven to succeed in helping people and organizations perform at an optimal level. The human services professional must have an array of knowledge and a skillset that helps them understand people, both as individuals and within groups. This requires knowledge of a variety of factors in human behavior. The human services worker must be familiar with human development, how culture and society impact behavior and the influence of economic structures on human behavior.
