OCN® Certification

The OCN® examination tests the knowledge necessary for the nurse to practice competently at the basic level in adult oncology nursing. This certification validates an individual's specialized knowledge in cancer nursing. Candidates who pass the OCN® Test may use the certification mark "OCN®" to verify that they have met all eligibility and testing requirements. The certification mark may be used only as long as certification is valid. OCN® certification is valid for four years.

The 2013 Oncology Nursing Certification Test Bulletin contains information you need to know before applying for an ONCC test. It includes information about test content and certification policies. When you apply for a test, you must affirm you have read, understand, and accept the conditions described in the Bulletin about test administration, reporting of scores, and certification policies. ONCC strongly recommends that you review the current Test Bulletin. Use the links below to obtain specific information about the steps involved in taking a test.
