The Joint Commission evaluates and accredits more than 20,000 health care organizations and programs in the United States. An independent, not-for-profit organization, The Joint Commission is the nation's predominant standards-setting and accrediting body in health care. Since 1951, The Joint Commission has maintained state-of-the-art standards that focus on improving the quality and safety of care provided by health care organizations. The Joint Commission's comprehensive process evaluates an organization's compliance with these standards and other accreditation or certification requirements. Joint Commission accreditation and certification is recognized nationwide as a symbol of quality that reflects an organization's commitment to meeting certain performance standards. To earn and maintain The Joint Commission's Gold Seal of Approval™, an organization must undergo an on-site survey by a Joint Commission survey team at least every three years. (Laboratories must be surveyed every two years.)
