Here is a helpful list of some of the most common abbreviations and acronyms. If you do not see the acronym you are looking for in one category, check out the others. This is not an exhaustive list, so the acronym you are looking for may not be here. Many professionals will list both a license and a national certification. For example, a professional counselor may place both LPC (for Licensed Professional Counselor) and NCC (for Nationally Certified Counselor) after his/her name and degree.
Some helping professions, such as art therapy, are not licensed separately in many states. In such cases, practitioners will be licensed in a related professional field, and certified by a national association in their chosen profession. In the example above, a Registered Art Therapist (ATR) may be licensed as a psychologist (Licensed Psychologist), clinical social worker (LCSW), or professional counselor (LPC).
Other professionals may have dual credentials, such as being licensed both as a professional counselor (LPC) and a marriage and family therapist (LMFT). A clinical social worker (LCSW) may also be certified as an employee assistance professional (CEAP). This makes for extra designations on their business cards, letterheads, and phone listings.
Each helping profession has its own set of educational requirements. Some professions, such as psychiatry and clinical psychology, require their practitioners to earn doctorates (such as an MD, PhD, or PsyD). Others, including professional counseling and social work, require only a master's degree (such as an MA, MS, or MSW). In the fields that allow a master's degree for licensure, some practitioners earn a doctorate in order to obtain advanced training and to teach in graduate programs in their fields.
