The Progressive Care Certified Nurse (PCCN) exam is administered by the American Association of Critical-Care Nurses (AACN), which is the largest specialty nursing organization in the world. The PCCN examination tests applicants' knowledge of caring for acutely ill adult patients.

Nurses interested in this certification may work in areas such as intermediate care, direct observation, stepdown, telemetry, transitional care or emergency departments.
