What are the CRNI eligibility requirements?

A current, active, unrestricted RN license in the United States or Canada, plus a minimum of 1,600 hours of experience in infusion therapy as an RN within the past two years. That experience can be in nursing education, administration, research, or clinical practice within the infusion specialty, INCC states that direct bedside care is not required.

How is the CRNI exam structured?

The 2.5-hour, computer-based exam consists of 140 four-option multiple-choice items, of which 120 are scored and 20 are unscored pretest items. The 120 scored questions are split across three core areas: Principles of Practice (35), Access Devices (39), and Infusion Therapies (46). It is offered during March and September at PSI test centers.

What score do I need to pass the CRNI exam?

Your result is reported as pass or fail based on your raw score (the number of questions answered correctly). INCC sets the minimum passing score using the Angoff method, a criterion-referenced approach, and adjusts it across forms through pre-equating. INCC does not publish a fixed numeric cut score or an overall pass rate.

How much does the CRNI exam cost?

INCC's published fees are $335 (member) / $475 (non-member) by the early-bird deadline, rising to $385/$525 at the regular deadline and $435/$575 at the late deadline, with an additional $140 international site fee where applicable. Unsuccessful candidates who retake the exam qualify for a $50 discount. Confirm current pricing with INCC.

How long is the CRNI good for and how do I renew?

Three years. You recertify by earning 40 CRNI Recertification Units (RUs) within the cycle, at least 30 from national INS meetings or INS Virtual Education Conferences, or by retaking the exam in your final certification year. Recertification also requires 1,000 hours of infusion-therapy experience in the previous three years and an active RN license. Confirm current requirements with INCC.

About the credential

The CRNI (Certified Registered Nurse Infusion) is administered by the Infusion Nurses Certification Corporation (INCC), which describes it as the only specialty certification for infusion nurses that is nationally recognized and accredited. INCC is affiliated with the Infusion Nurses Society (INS) but is legally and financially independent. The exam is scored on 120 multiple-choice questions across three core areas of infusion therapy, Principles of Practice, Access Devices, and Infusion Therapies. This guide covers the exam format, an efficient study plan built from INCC's content outline, eligibility, fees, and the three-year recertification cycle.

Who pursues it

Infusion and vascular-access RNs validating their specialty knowledge
Nurses in home infusion, ambulatory infusion centers, or acute-care infusion roles seeking a certification differential
RNs in infusion education, administration, or research who meet the 1,600-hour experience rule and want the credential as a resume differentiator

Does the CRNI actually raise your pay? (The honest answer)

~60%

of nurses got no direct pay bump for certifying

$1-2/hr (~$2,000-4,000/yr full-time) where a differential exists

typical raise when employers do pay

$1,000-2,000 one-time at some employers

one-time bonus where offered

Here is the part INCC and prep vendors will not lead with: in a large national compensation survey, about 60% of nurses received no direct pay increase for becoming certified. When the CRNI does pay, it is typically $1-2/hr or a one-time bonus set by your employer, not by INCC. Infusion is a defined specialty (hospital infusion teams, ambulatory and standalone infusion centers, home infusion, and vascular-access roles) where the CRNI is often expected on a clinical ladder or preferred for specialized and home-infusion positions, but the raise, if any, comes from your employer's policy. Ask HR for the exact amount before you assume a bump.

When it's worth it anyway

Your employer has a clinical ladder or certification differential; confirm the dollar amount with HR before you sit the exam.
You work in or are moving into a dedicated infusion, ambulatory-infusion, home-infusion, or vascular-access role where the CRNI is expected or preferred.
You want the credential as a resume differentiator for specialized infusion and home-infusion positions that screen for it.
You want the structured knowledge and confidence for safer, more autonomous infusion therapy and vascular-access practice.

Eligibility

A current, active, unrestricted registered nurse (RN) license in the United States or Canada

A study plan that works

1Weeks 1-2: Map INCC's three-domain content outline and weight your schedule to it. The exam is scored on 120 questions split Principles of Practice (35), Access Devices (39), and Infusion Therapies (46), so let those weights set your priorities and take a diagnostic early.
2Weeks 1-6: Run a question bank or the INCC practice questions daily. Items are written at recall and application levels, so daily reps with thorough rationale review are the spine of the plan; reading is what you do to fix the misses.
3Weeks 2-4: Front-load Access Devices (the heaviest single area). Drill peripheral, midline, and central devices (PICC, tunneled, non-tunneled, implanted ports), maintenance and care, and device-related complications such as infiltration, extravasation, and catheter occlusion.
4Weeks 3-5: Cover Infusion Therapies. Fluid and electrolyte balance carries the most weight here, plus parenteral nutrition, anti-infectives, blood products, antineoplastics, biologics, and therapy-related complications including exposure to hazardous drugs.
5Weeks 4-6: Lock down Principles of Practice. Anatomy and physiology, infection prevention and control (epidemiology, chain of infection, bloodstream infections), and phlebotomy.
6Weeks 4-6: Anchor on the Infusion Therapy Standards of Practice. Several sample items reference the INS Standards directly, so know the current standards for device selection, dwell, and complication management.
7Weeks 7-8: Switch to timed, mixed practice. Full-length sets under exam conditions build stamina for 140 items in 2.5 hours and rehearse pacing.
8Final week: Consolidate, do not cram. Work your error log and a high-yield complications-and-electrolytes sheet, and confirm your PSI test-center logistics.
9Throughout: Keep one error log. Reviewing your specific missed questions in the final week is the highest-return study activity.

Which exam to take

The CRNI is the broad infusion-therapy credential, covering access devices, infusion therapies, and the underlying principles of practice. A narrower alternative is the VA-BC (Vascular Access Board Certified), administered by the Vascular Access Certification Corporation, which focuses specifically on vascular access. Most infusion-specialty RNs pursue the CRNI for its breadth; choose based on which scope matches your role, and confirm current eligibility and format with each certifying body before you register.

Keeping it current

The CRNI credential is valid for three years, contingent on continuous RN licensure. You recertify by earning 40 CRNI Recertification Units (RUs) within the three-year cycle, at least 30 of which must come from national INS meetings or INS Virtual Education Conferences, or by passing the exam again during your final year of certification. Recertification also requires documentation of 1,000 hours of infusion-therapy experience in the previous three years and an active, unrestricted RN license. The recertification fee is $200 for INS members and $325 for non-members. Confirm current requirements with INCC.
