1975
The Oncology Nursing Society (ONS) was founded with a primary focus on educating and developing oncology nurses and the specialty of oncology nursing. As ONS grew, the membership became interested in developing a means to formally recognize professional expertise in oncology nursing.
1981
The ONS Board appointed the Certification Task Force to develop a plan to implement a certification program.
1983
This task force met with more than 800 ONS members during the ONS Annual Congress in San Diego to identify members’ views on certification. It was clear that certification was a high priority for many of the organization’s members.
1984
The Oncology Nursing Certification Corporation (ONCC) was separately incorporated in the state of Pennsylvania and the first Board of Directors meeting was convened to finalize the ONCC structure and develop corporate policies.
1985
The American Cancer Society (ACS) awarded ONCC a $35,000 grant to develop a certification program.
April 30, 1986
ONCC administered the first OCN® examination to 1,607 nurses during the ONS Annual Congress in Los Angeles; 1,384 (86%) passed.
1991
ONCC Board appointed a task force to explore advanced certification.
1994

256 nurses took the first Advanced Oncology Certified Nurse (AOCN®) Examination; 219 passed (86%).
1998

1999
ONCC purchased the Certified Pediatric Oncology Nurse (CPON®) Examination from the Certification Corporation of Pediatric Oncology Nurses. ONCC offered the first CPON® exam in October 1999 during the annual conference of the Association of Pediatric Oncology Nurses (now the Association of Pediatric Hematology Oncology Nurses). 183 nurses took the first CPON® examination administered by ONCC; 141 passed (77%).
2000
ONCC obtained accreditation from the National Commission for Certifying Agencies (NCCA), whose purpose is to help ensure the health, welfare, and safety of the public through the accreditation of certification programs/organizations that assess professional competence. At the time, ONCC offered the OCN®, AOCN®, and CPON® credentials. Since then, all ONCC certification programs have obtained NCCA accreditation as soon as eligible and maintained it continuously.
2005
ONCC introduced two role-specific advanced certification examinations: the Advanced Oncology Certified Nurse Practitioner (AOCNP®) and Advanced Oncology Certified Clinical Nurse Specialist (AOCNS®). 268 nurses took the AOCNP® test during its first year; 232 passed (87%). 113 nurses took the AOCNS® test in 2005, and 94 passed (83%). With the introduction of the AOCNP® and AOCNS® examinations, the AOCN® credential was placed in retired status, meaning nurses could maintain the credential through professional development but the test would no longer be offered.
2009
ONCC began offering the Certified Breast Care Nurse (CBCN®) examination, the first subspecialty certification test. 381 nurses took the CBCN® test in its first year; 329 passed (86%).

Of the 519 nurses who took the CPHON® examination, 374 passed (72%). With the introduction of the CPHON® credential, the CPON® credential was placed into retired status, meaning it could be maintained by nurses through professional development, but the test would no longer be offered.
