The Oncology Nursing Certification Corporation (ONCC) is a nonprofit organization established for the development, administration, and evaluation of programs for certification in oncology nursing. Incorporated in 1984 and governed by a board of directors, ONCC is the certifying body for oncology nursing and meets standards established by the Accreditation Board for Specialty Nursing Certification. It is accredited by the National Commission for Certifying Agencies.[1][2]

All ONCC certification candidates must hold an active, unencumbered RN license to be eligible to take an ONCC examination. In addition, each ONCC certification has specific eligibility criteria for education and experience that must be met before the candidate takes the examination.[7]


All ONCC examinations are offered at more than 300 computer-based testing centers located in North America and at selected international test sites. Certification is granted to candidates who meet the eligibility criteria and successfully complete a comprehensive multiple-choice examination.[8]


There are three components to certification renewal: practice hours, professional development activities, and successful retesting. Two of the three components must be met to renew certification. Three renewal options are available, based on the combinations of these renewal components.[9]

  • Option 1: practice hours + professional development activities
  • Option 2: practice hours + successful testing
  • Option 3: professional development activities + successful testing
