At ONCC®, we believe certification makes good oncology nurses even better.
ONCC is the premier provider of nationally accredited certification for nurses in oncology and related specialties. Founded in 1984 as a non-profit organization, ONCC administered the first Oncology Certified Nurse (OCN®) examination in 1986. Today, ONCC offers eight credential programs and has more than 39,000 currently certified nurses.
All ONCC certification examinations are accredited by the National Commission for Certifying Agencies. NCCA is an independent organization that has identified the essential components of a national certification program and determines if credentialing organizations meet established standards based on those components. These standards are nationally recognized principles used by a variety of organizations for certification programs in diverse professions. NCCA accreditation indicates that ONCC programs have been evaluated by the Commission and meet or exceed all of its standards.
The mission of ONCC is to promote health and safety by validating competence and ensuring life-long learning in oncology nursing and related specialties.
Oncology care across the continuum is provided by oncology certified professionals.
Our Code of Ethics
The Code of Ethics sets forth values, ethical principles, and standards to which professionals aspire and by which their actions can be judged. The purpose of this code is to identify the moral obligations of all ONCC-certified nurses inherent in their professional roles. Specifically, ONCC-certified nurses are obligated to support and maintain the integrity of the profession of oncology nursing in order to promote the health and well-being of patients and families. Read the Code of Ethics.
Values are our organizations’ guiding principles. They represent our core beliefs for the Oncology Nursing Society (ONS) and its family of affiliated corporations, including the Oncology Nursing Foundation, Oncology Nursing Certification Corporation.
The organization and its certificants exhibit integrity and earn trust through ethical behaviors and uncompromising professionalism to all parties in business, professional, and personal interactions.
ONCC and its certificants face every endeavor with creativity and knowledge. We strive to apply our broad perspectives consistently while leading the transformation of cancer care.
We, as an organization and as individuals, advocate on behalf of people with cancer to ensure their quality of life and their access to exemplary care throughout the continuum of life. We advocate on behalf of the nursing profession and the oncology specialty to ensure respect and recognition.
We strive to foster excellence in oncology nursing practice. We are committed to nothing less than excellence in our organization, certification processes, and the care of patients.
We respond quickly and effectively to the dynamic situations that impact oncology nurses and their care of patients with cancer.
