The CBCN is valid for four years, and ONCC lets you renew through a personalized learning plan
rather than retaking the exam each cycle. Here’s what ONCC requires.
How long is the CBCN valid?
Four years from the date you certify.
How do you renew?
ONCC uses the ILNA (Individual Learning Needs Assessment): you assess yourself
against the CBCN content areas, then earn points (continuing education and professional activities)
targeted to your needs. Renewal also requires recent RN experience and breast-care practice hours, as
specified by ONCC.
Plan ahead
Because the ILNA is tailored to your gaps, complete the assessment early so you can direct your CE
where it counts — and log activities as you earn them.
