Nearly half of accredited CRNA programs require the CCRN, and about a quarter more recommend it. If you're eligible, earning it before you apply keeps the most programs open and shows your critical care knowledge.
The CCRN is a specialty certification from the American Association of Critical-Care Nurses (AACN). This page explains eligibility, the exam, and how programs treat it.
What the CCRN is
The CCRN certifies nurses who provide direct care to acutely or critically ill patients. AACN offers it for three populations: adult, pediatric and neonatal. Most CRNA applicants take the adult exam, but you test in the population you actually care for.
AACN recognizes the certification for three years, after which you renew.
Eligibility
You need a current, unencumbered US RN or APRN license. You also need to meet one of two clinical practice options:
| Option | Direct care hours | Recent hours |
|---|---|---|
| Two-year option | 1,750 hours in the previous 2 years | 875 of them in the most recent year |
| Five-year option | At least 2,000 hours over 5 years | 144 of them in the most recent year |
The hours must be in direct care of acutely or critically ill patients in the population you're testing for. Orientation hours can count when you are the assigned nurse giving care. Hours spent shadowing another nurse do not count.
You give AACN the name of a professional colleague who can verify your hours. AACN may contact them.
What this means for your timeline
1,750 hours is roughly a year of full-time work, but it depends on your schedule. Many nurses become eligible around the same time they meet the one-year ICU minimum for CRNA school. Check your own hours before you plan an application cycle around the exam.
The exam
According to AACN:
- The exam is three hours long with 150 questions, of which 125 are scored.
- It's offered year-round by computer at testing centers across the US.
- You can take it up to four times in a 12-month period.
- The fee is $260 for AACN members and $375 for nonmembers.
Fees and policies change, so confirm on AACN's site before you register.
How CRNA programs treat the CCRN
Everything CRNA's School Finder data (October 2026) shows these policies across the 154 accredited programs:
| CCRN policy | Programs |
|---|---|
| Required | 72 |
| Recommended or preferred | 38 |
| Not required | 27 |
| Case by case | 4 |
| Varies by track | 1 |
| Not stated | 12 |
So 72 programs, about 47%, require it, and 38 more recommend it. Some want it before you apply, others before your interview or start date.
A few ask for your score report. Read the exact wording on each program's site.
If you aren't eligible yet, see our list of CRNA schools that don't require the CCRN. You can also use our schools I qualify for tool to filter programs by CCRN status.
Why programs value it
- It's an outside check on your knowledge. Grades and references vary a lot. A standardized exam is easy to compare.
- It covers material you'll use in anesthesia school. Cardiovascular, pulmonary and multisystem topics overlap with interview questions and early coursework.
- It shows commitment. Studying for and passing a hard exam while working full time signals you can handle a demanding program.
The CCRN doesn't replace strong ICU experience. Committees still look closely at the acuity of your unit and the skills you use. See best ICU for CRNA school.
How to prepare
- Confirm your hours against AACN's eligibility options.
- Download the exam blueprint from AACN so you know the topic weighting.
- Give yourself 6 to 12 weeks of steady study, depending on your background.
- Use practice questions heavily, and review why each wrong answer is wrong.
- Focus on your weak systems. If you work in a medical ICU, spend extra time on cardiac surgery and trauma topics.
- Book the exam early so you have a buffer before application deadlines.
Some employers pay the exam fee or offer a bonus for certification. Ask your unit educator.
What about other certifications?
The CCRN is the certification programs name most often. Life support cards are a separate matter. The COA requires students to hold ACLS and PALS before clinical work, and most programs also ask for BLS.
FAQ
Do I need the CCRN to get into CRNA school?
At about half of programs, yes. At most others it's recommended. Check each program, and earn it if you're eligible.
Can I apply while I'm still studying for the CCRN?
Some programs allow it if you pass by a set date. Others require it at the time of application. Ask the program.
Does the pediatric or neonatal CCRN count?
Usually, if the program accepts your pediatric or neonatal ICU experience. See schools that accept PICU experience and schools that accept NICU experience.
Does a high CCRN score help?
Some programs ask for the score report, so a strong score can help there. Elsewhere, passing is what counts.
