Infusion nurse certifications compared: CRNI, VA-BC, OCN and more
The main certification for infusion nurses is the CRNI®, from the Infusion Nurses Certification Corporation. Two others often come up: VA-BC™ for vascular access specialists and OCN® for oncology nurses. Oncology infusion roles may also want the ONS/ONCC® Chemotherapy Immunotherapy Certificate™, which is a course credential, not a board certification. None of these is required to get your first infusion job.

Which do employers ask for?
CRNI comes up most: it's mentioned in 27% of infusion RN job descriptions on this site (56 of 208). OCN appears in 2% and VA-BC in 0%. In most posts these are listed as preferred, so they help you stand out and negotiate rather than decide whether you get hired. See infusion nurse requirements for what posts actually require.
Which one should you get?
- Staying in infusion, any setting: CRNI. It's the specialty's own credential. See our CRNI certification guide.
- Placing PICCs or on a vascular access team: VA-BC. See our VA-BC guide.
- Oncology infusion: start with the chemo certificate if your employer requires it, then consider OCN. See our oncology infusion nurse guide.
What about "IV certification" courses?
Short IV therapy courses teach IV insertion and infusion basics. They can be useful training, but they are certificates of completion, not board certifications like the three above, and whether an employer or state accepts one varies. If you're an RN, hands-on IV experience usually counts for more with infusion employers than a course certificate.
The ONS/ONCC chemo certificate
The ONS/ONCC® Chemotherapy Immunotherapy Certificate™ is a course with a post-test, valid for two years. ONS describes it as "neither a professional certification nor licensure". Many oncology employers still require it before you give chemotherapy on your own.
