How Many Shadow Hours for CRNA School? The Real Number

Updated September 2026

Short answer on how many shadow hours for CRNA school: aim for 30 to 40. Most programs don't publish a number, and in our database of 154 accredited programs only 55 require shadowing at all. But competitive applicants show up with close to 40 hours.

So how many shadow hours for CRNA school do you actually need?

Okay, so you're sitting there with 8 hours and you saw someone on Reddit say they had 60, and now you feel like you're already behind. I get it. Let me give you the real number first and then we'll talk about where it comes from.

So, 30 to 40 hours. That's the target. If you can get 30 to 40 hours, 100%, go for it. Competitive applicants have close to 40 hours and truly the more the better, and I've been saying that for years because it keeps being true.

But I'm not saying 8 hours makes you unapplicable. It doesn't. Plenty of people get in with less, and a lot of programs never ask you for a total at all. What I am saying is that hours are one of the few parts of this application you can just go get. You can't un-take a chemistry class from 2019. You can text a CRNA this week.

And there's a reason I push the higher end. The more hours that you shadow, the better, because the shadow days are what you draw on in the essay and in the interview. One day gives you one story. Five days gives you a point of view. That difference shows up in an interview room fast.

Is shadowing required for CRNA school, or just recommended?

And this is the question I get the most, and the honest answer annoys people. It's both.

In our database of 154 accredited programs, 55 require shadowing. 94 don't require it. And 5 don't say one way or the other, which means you're emailing them. So if you're doing the math, the majority of programs technically do not make you shadow.

But you know what? I still think it's practically essential. Here's how those two things live together. The 94 programs that don't require it still ask you in the interview why anesthesia, and "I shadowed four CRNAs and here's what surprised me" is a different answer than "I've always been interested in it." Same application, different room.

But one more thing about that 55. Required almost never comes with a published hour count. A program will tell you they want shadowing documented and then leave the number completely blank, which is maddening when you're trying to plan. So when a program does list a minimum, treat that minimum as the floor and not the goal.

Why don't programs just tell you the number?

Listen, I wish they would. I've stared at plenty of program pages that say "shadowing experience preferred" and nothing else, and that's not helpful when you're trying to book time off.

So part of it is that they're reviewing you as a whole person and they don't want a number to become a checkbox. Part of it is that access to CRNAs is wildly different depending on where you live. Somebody in a metro with four anesthesia groups has an easier time than somebody rural with one critical access hospital, and programs know that.

I'm not defending the vagueness. It genuinely sucks for planning. But it does mean you get to decide what "enough" looks like, and my answer is 30 to 40 because that's what the strong applications tend to have.

And if a program page is blank, don't sit there guessing with me. It is your responsibility to reach out to the program and find out these answers yourself. A one line email asking "do you require documented shadowing hours, and is there a minimum" gets answered more often than you'd think.

How many different CRNAs and settings should you shadow?

So this is where I'd rather you spend your energy than chasing raw hours. Twelve hours across three CRNAs in two settings beats twelve hours following one person around one OR. Let me count out what I'd actually go get.

1. Number one, at least two or three different CRNAs. Different people, different styles, different opinions about the job. One CRNA having a rough Tuesday shouldn't be your whole impression of the profession.
2. Number two, more than one setting if you can swing it. A big academic OR, a community hospital, an outpatient surgery center, OB. They feel like different jobs. They kind of are.
3. Number three, at least one full day, not a string of four hour visits. The pre op, the induction, the boring middle where everything is stable, the wake up. The boring middle is the part nobody warns you about and the part you should see.
4. Number four, a CRNA who does their own cases without an anesthesiologist in the room if that's available to you. Independent practice looks different. Worth seeing once.

I'm not saying you need four settings and six CRNAs before you're allowed to apply. If you get one CRNA who lets you come back three times, that's a great outcome and you should take it. Variety is the upgrade, not the requirement.

And finding these people is its own project. State meetings are your number one way. Go look at our post on how to find a CRNA to shadow, because that's a whole different conversation than this one.

So once somebody says yes, don't blow the day by showing up wrong. We have a separate post on what to wear and bring to a shadow day, and another on the questions to ask while you're there. Read both before your first one. Those two things are the difference between 8 hours of standing quietly and 8 hours you can write about.

How do you log shadow hours so they actually count?

And here's where people lose hours they already earned, and it makes me a little crazy. You shadowed in March. You apply in September. You cannot remember the date, the facility, the CRNA's last name, or whether it was six hours or eight.

So log it the same day. Not the same week. The same day, in the parking lot, before you drive home.

• Date, start time, end time. Actual times, so the total isn't a guess.
• Facility and unit or OR.
• The CRNA's full name, credentials and an email or phone. You may need a signature later.
• Two or three lines about what you saw. The case, the airway, something they said that stuck.
• One line on what surprised you. That line is the one that turns into essay material.

That last one matters more than the hour count. People show up to an interview with 40 documented hours and absolutely nothing to say about any of them, and you can watch the panel lose interest in real time. Hours without observations are just attendance.

And a lot of the 55 programs that require shadowing want a signed form, which is really hard to chase down eight months after the fact. We have a shadowing form and log you can use so you're not rebuilding it from memory. Get the signature while you're standing there.

Do your shadow hours expire or get too old for CRNA school?

So what if you shadowed three years ago, back when you first started thinking about this? Does that still count?

So, usually yes, and I want to take that stress off your plate. Shadowing doesn't have a standard expiration the way some prerequisite coursework does. But some programs do put a recency window on it, and no, I'm not going to guess which ones yours are. Check the program, because that's the only answer that's actually true for your list.

But here is what I'd do. If your hours are more than about two years old, go get one more day. Not because the old ones are worthless, but because anesthesia in 2026 is what they're going to ask you about, and a fresh day gives you a current story. Plus the new form is easy to get signed.

And if you shadowed as a nursing student, that's a little different. It counts as exposure, but you were a different person clinically then. A day as an experienced ICU nurse hits differently because you actually understand the drips now.

And shadowing isn't only about the application. Shadowing is 10% of our ReadyScore, and honestly the bigger reason to do it is that a few days in an OR is the cheapest way to find out whether you want this job before you spend three years and a lot of money on it.

Our Final Thoughts

If I was applying again, I would shadow again, and I would do more shadowing. That's not me being a go-getter about it. It's that the days I'd have to talk about in an interview are worth more than the number on the form. So get to 30 or 40 if your life allows it, log every day the day it happens, and stop comparing your 8 hours to a stranger's 60.
