The National Committee for Quality Assurance (NCQA) is a non-profit organization that measures and reports on the quality of health care provided by managed care organizations, health insurance plans, and other providers of health care services. They have developed a set of standards and guidelines for evaluating and reporting on the quality of care, and they also provide accreditation and certification programs to recognize organizations that meet these standards. The goal of NCQA is to improve the quality of health care and promote greater transparency and accountability in the health care system.
