Nursing Career Paths: How to Become a Nurse, From CNA to NP and CRNA
Nursing isn't one path, it's a lattice of entry points and bridges. Here's how to become a nurse at every level from CNA through DNP, how long each step takes, what it costs, and the licensing data from NCSBN, AACN, and HRSA that most program brochures leave out.
Where to Start, Based on Where You Are Now
The right next step depends less on this guide and more on where you're starting from. Find yourself below.
New to healthcare entirely. If you've never worked in patient care, becoming a CNA is usually the fastest, cheapest way to find out whether bedside work is really for you, in 4 to 12 weeks for a few hundred dollars. It's not the only entry point (plenty of people go straight into an accelerated BSN if they're already sure), but it's the lowest-risk way to test the water before committing years and tens of thousands of dollars to a nursing degree.
Already working as a CNA, LPN, or RN and ready to move up. You're the person this guide is mostly written for. The honest planning question isn't "which program is fastest," it's "how much of my current schedule can I actually give up." A part-time bridge that fits around a full-time job almost always beats an accelerated program that assumes you can stop working, because most people can't.
Switching careers from outside healthcare. An accelerated BSN (12 to 18 months) or a direct-entry MSN (for those who already have an unrelated bachelor's degree and want to go straight for advanced practice) are both built specifically for career-changers. You'll be competing for admission against people with more recent science coursework, so brushing up on prerequisites before applying matters more than it does for a traditional student.
How to Become a Nurse: Every Step From CNA to DNP
Each step below shows the typical timeline, cost, and credential required to reach it, along with the detail most guides skip. Tap any step for the full breakdown.
1CNA (Certified Nursing Assistant)Entry pointThe fastest, cheapest way into direct patient care, and a good way to find out if bedside work is really for you.Timeline: 4–12 weeksCost: $400–$2,500Credential: State competency exam (NNAAP or a Prometric equivalent)
This is where most people start, and for good reason: 4 to 12 weeks, $400 to $2,500, no prior healthcare credential needed. You'll sit for a state competency exam, most commonly Credentia's NNAAP or a Prometric equivalent, which mixes multiple-choice questions with a hands-on skills check. Most states let you retake it up to three times if you don't pass the first time, so it's not a one-shot deal. A lot of nurses we hear from say CNA work taught them more about whether they actually wanted to be at the bedside than anything in a classroom did, before they'd spent real money finding out.
2LPN/LVN (Licensed Practical or Vocational Nurse)Independent licenseA one-year program that gets you licensed and earning more, without committing to a full nursing degree yet.Timeline: ~12 monthsCost: $3,344–$12,413Credential: NCLEX-PN
About a year at a community college, typically $3,344 to $12,413. You'll sit for the NCLEX-PN at the end, and the numbers are worth knowing going in: NCSBN's latest data puts the overall pass rate at 77.3%, with first-time test-takers passing at 86.6% and people retesting at 41.7%. Some LPNs stay at this level for their whole career and build real expertise here. Others treat it as a paid way to build savings and experience before bridging into an RN program, which is one of the most common reasons people choose this route over going straight for an ADN or BSN.
3RN via ADN (Associate Degree in Nursing)RN licensureThe fastest route to full RN licensure, and still how a large share of new RNs get there.Timeline: 2 yearsCost: $15,000–$30,000Credential: NCLEX-RN
Two years, $15,000 to $30,000, and you come out with full RN licensure through the NCLEX-RN. Here's something worth knowing before test day: the pass rate dropped in 2025, from 73.3% the year before down to 69.1% overall, and the gap between passing on your first try and passing on a retest is steep: 86.7% versus 52.7%. If you don't pass the first time, that's a genuinely ordinary outcome, not a sign you picked the wrong career. Associate-degree grads pass at 86.1% on their first attempt, right in line with bachelor's-degree grads at 87.6%, so the credential itself isn't what's driving pass rates. Preparation is.
4BSN (Bachelor of Science in Nursing)Degree upgradeOpens more specialty and leadership doors than an ADN. The real question is how fast you can realistically finish a bridge.Timeline: 4 years direct, or 8–30+ months as an RN-to-BSN bridgeCost: $40,000–$100,000+ direct; bridge cost varies by schoolCredential: NCLEX-RN (if entering directly) or none (if you're already an RN)
A traditional four-year BSN runs $40,000 to $100,000 or more. But if you're already an RN with an ADN, the bridge is the more common route, and here's the one number that actually controls your timeline: full-time versus part-time. Full-time-accelerated bridges advertise as fast as 8 months. Part-time, the realistic pace for most working nurses, runs 30-plus months, sometimes 2 to 4 years. Schools tend to lead with the 8-month number because it's the impressive one, but most advisors will also tell you not to keep working full-time while doing it, which most people simply can't afford. Plan around the part-time number and treat anything faster as a bonus.
5MSN: Nurse Practitioner (NP)Advanced practiceThe advanced-practice track most people picture first, and one where the MSN and DNP routes end at the exact same exam.Timeline: 12–24 months on top of a BSNCost: Varies by program; direct-entry MSN for career-changers runs $50,000–$125,000+Credential: National NP board certification (ANCC or AANP, roughly $315–$395)
A full MSN-NP program rarely finishes in under 12 months, since you need 500 to 700 clinical hours regardless of how the school markets its timeline. Career-changers without a nursing background often go through a direct-entry MSN instead: 20 to 24 months to become RN-eligible, then another 1 to 2 years of graduate coursework, running $50,000 at public schools up to $100,000-$125,000-plus at private ones. Here's the detail almost nobody explains clearly before you choose a program: MSN-prepared and DNP-prepared nurse practitioners sit for the exact same national board exam and end up with the exact same NP credential. Choosing a DNP over an MSN isn't about being able to do more clinically. It's a bet on leadership, teaching, or research down the road.
6CRNA (Certified Registered Nurse Anesthetist)Advanced practiceThe highest-paid nursing specialty, now doctoral-entry, and one where the workforce data tells a surprising story.Timeline: 14–36 months of doctoral training, after ICU experienceCost: Program tuition varies; certification exam $1,310Credential: NBCRNA National Certification Exam
CRNA training is doctoral-level now, running 14 to 36 months and built on top of a BSN plus real critical-care experience. The certification exam is 100 to 170 questions over 3 hours, costs $1,310, and gives you up to 4 attempts within a 2-year window if you need them. Here's something that might surprise you: the federal government's own workforce projections actually show CRNAs, along with NPs and nurse midwives, in national surplus through 2037. The real staffing problem isn't a shortage of these roles nationally, it's that they're unevenly spread across the country. Where you're willing to work matters more than the national headline.
7DNP (Doctor of Nursing Practice)Doctoral / leadershipA leadership and systems-level credential layered on top of clinical practice, not a substitute for it.Timeline: 3–4 years full-time from a BSNCost: Program-dependent, generally the highest tier on this pathCredential: Doctoral degree; NP or CRNA licensure still requires its own board exam
Three to four years full-time from a BSN. The DNP is built for leadership, faculty, and health-systems roles, and it doesn't replace the board exam you still need for NP or CRNA licensure. It matters at a workforce level too: nursing PhD enrollment has fallen for 11 straight years, and nursing schools nationally are short on faculty, with a 7.2% vacancy rate. That shortage is a real reason 92,672 qualified applicants got turned away from nursing programs in 2025, not because interest in nursing dropped, but because schools didn't have the faculty and clinical placements to teach them.
What Actually Determines How Long It Takes to Become a Nurse
The steps above describe the paths. These five decisions determine how fast any individual nurse actually progresses.
Full-time versus part-time is the real timeline lever. Every bridge program on this path advertises its fastest possible pace, which is almost always the full-time-accelerated option. Most working nurses can't stop working to hit it, so the honest planning number is the part-time timeline, which usually runs two to three times longer.
Skipping the bridge entirely is sometimes the faster option. Going straight for a BSN or direct-entry MSN from the start can sometimes reach the same destination faster than stacking CNA, then LPN, then bridging twice. The stacked path costs less at each individual step, but paying application and entrance-exam fees three or four times adds up in a different way.
NCLEX timing has a real seasonal pattern. First-time NCLEX-RN pass rates hit 89.1% in the second quarter of the year but only 81.2% in the fourth. Nobody should build a career around a testing calendar, but if there's any flexibility in when you sit for the exam, that's a real, documented data point most advisors never mention.
MSN versus DNP for NP practice is about positioning, not scope. An MSN-FNP and a DNP-FNP take the same board exam and get the same NP credential. Choosing the DNP makes sense if leadership, teaching, or a future doctoral requirement is the goal, not because it lets you practice more clinically than an MSN would.
The shortage numbers genuinely disagree with each other. Two of the most-cited sources on the nursing shortage, AACN and HRSA, don't actually agree: they name different states as hardest hit and put different percentages on the states they do share. If you're planning a career around "there's a shortage so I'll always find work," know that the picture varies a lot by region and specialty, and that advanced-practice roles specifically are projected to be in surplus nationally, not shortage.
Mistakes That Slow Down Nursing Career Progression
Based on the same NCSBN, AACN, and HRSA data cited throughout this guide, here's what most commonly derails or delays someone's plan:
1. Assuming there's one correct order to follow. CNA, then LPN, then RN, then BSN is one path, not the only one. Direct-entry and accelerated BSN programs exist specifically for people who don't need or want the stacked route. The right order depends on your budget and timeline, not on which path sounds most traditional.
2. Planning your life around the brochure timeline. An RN-to-BSN bridge advertised as "as fast as 8 months" is describing the full-time-accelerated track. Build your plan around the realistic part-time number instead, and let a faster pace be a pleasant surprise rather than the expectation you're disappointed by.
3. Treating a first NCLEX failure as a sign you picked the wrong career. The gap between a first attempt (86.7%) and a retest (52.7%) is real, but it makes a first failure statistically ordinary, not a red flag about your fitness for nursing. What actually moves the needle on a second attempt is a real study plan, not just trying again cold.
4. Choosing a DNP for the wrong reason. If the goal is broader clinical scope, a DNP won't get you there any further than an MSN would, since both end at the same board exam and the same NP credential. The DNP makes sense for leadership or teaching goals, not for doing more at the bedside.
5. Assuming a nursing shortage guarantees an easy job search anywhere. Shortage headlines are national. Hiring conditions are local and specialty-specific. Advanced-practice roles are actually projected to be in surplus nationally, with the real challenge being where those nurses are willing to work, not how many exist.
How to Plan Your Path
Three principles that hold regardless of which step comes next:
Map the full cost curve before you enroll anywhere. The jump in cost isn't gradual across this path. Going from an ADN or BSN into a direct-entry MSN or CRNA-track doctoral program is the single steepest financial step. Knowing that before you start avoids a nasty surprise halfway through.
Plan around your real schedule, not the fastest advertised one. Before committing to any program, run the realistic part-time timeline as your baseline plan. Treat a faster pace as a bonus if life allows it, not as the plan itself.
Have your "why this next step" story ready before you need it. Whatever rung comes next, an interviewer or admissions committee for it will ask why you want it. Being able to answer that in specific, clinical terms reads very differently than checking the next obvious box.
Once you know which rung you're on and which one is next, the interview in front of you is easier to prepare for, because you know exactly what it needs to prove. See our AI interviewer for practice on that specific conversation.
Questions to Ask Before You Enroll or Bridge
Before committing to any program on this path, get real answers to these six questions from the program itself, not just its marketing materials:
What is this program's NCLEX pass rate for the last two graduating classes, not just its historical average?
Is this program accredited by ACEN or CCNE, the two bodies employers and state boards actually recognize?
What's the realistic part-time completion timeline, not just the fastest advertised one?
How are clinical placements guaranteed, and what happens if one falls through given how tight clinical sites are right now?
How many credits from my current CNA, LPN, or ADN background actually transfer in?
What's the current faculty-to-student ratio, given that faculty shortages are a real, documented bottleneck nationally?
Frequently Asked Questions
How long does it take to become a nurse?
It depends on which nursing license you're after. A CNA takes 4 to 12 weeks, an LPN about 12 months, and an RN 2 years through an ADN or 4 years through a BSN. Advanced practice adds more on top of a BSN: 12 to 24 months for a nurse practitioner, and 14 to 36 months of doctoral training for a CRNA after ICU experience. How long nursing school takes depends on which of these you choose, and full-time versus part-time enrollment stretches or shortens each one.
How do you become a registered nurse?
Pick a degree route, finish it, then pass the NCLEX-RN. The ADN is the fastest route, typically 2 years and $15,000 to $30,000 at a community college. The BSN takes 4 years and runs $40,000 to $100,000 or more. Choose a program accredited by ACEN or CCNE, since those are the accreditors employers and state boards recognize. Both degrees lead to the same NCLEX-RN and the same starting RN license from your state board of nursing.
LPN vs RN: what's the difference?
An LPN completes about a 12-month program and the NCLEX-PN, working under an RN or physician's supervision with a narrower scope of practice. An RN completes a 2-year ADN or 4-year BSN and the NCLEX-RN, with a broader scope that includes things like IV medication administration and complex care planning that most states reserve for RNs. Many LPNs later bridge to RN, which is why LPN is often a paid stepping stone.
How do you become an LPN, and how long does it take?
Complete a practical nursing program, usually about 12 months at a community college and typically $3,344 to $12,413, then pass the NCLEX-PN. NCSBN data puts the first-time NCLEX-PN pass rate at 86.6%, versus 41.7% for people retesting, so preparing well for the first attempt matters. In California and Texas the same role is called LVN (Licensed Vocational Nurse).
ADN vs BSN: which nursing degree should you get?
An ADN is faster and cheaper (2 years, $15,000 to $30,000). A BSN takes 4 years and $40,000 to $100,000 or more, but opens more specialty and leadership roles and is the standard prerequisite for NP programs. Both take the same NCLEX-RN, and first-time pass rates are nearly identical: 86.1% for ADN grads and 87.6% for BSN grads. Many nurses start with an ADN and finish an RN-to-BSN bridge while working, which runs 8 months full-time or 30-plus months part-time.
CNA vs LPN: what's the difference?
A CNA trains for 4 to 12 weeks, pays $400 to $2,500, and passes a state competency exam to provide hands-on personal care under nurse supervision. An LPN trains for about 12 months, passes the NCLEX-PN, and holds an actual nursing license with a wider clinical scope. CNA is the fastest way to test whether bedside work suits you. LPN is the first step that makes you a licensed nurse.
How long does it actually take to go from CNA to RN?
Through an ADN, plan on about 2 to 2.5 years of school after CNA certification. Through a CNA-to-LPN-to-RN bridge, plan on 2.5 to 4 years, depending on how long you work as an LPN first. Full-time versus part-time enrollment at each stage is what really moves this number.
How do you become a nurse practitioner, and how long does it take?
Earn a BSN, get licensed as an RN, then complete an MSN or DNP nurse practitioner program and pass a national NP board exam through ANCC or AANP (roughly $315 to $395). The MSN portion runs 12 to 24 months and rarely finishes faster, since you need 500 to 700 clinical hours regardless of how the school markets its timeline. Career-changers with an unrelated bachelor's degree can use a direct-entry MSN instead, which takes 20 to 24 months to reach RN eligibility plus another 1 to 2 years of graduate coursework.
NP vs DNP: do you need a doctorate to be a nurse practitioner?
No. MSN-prepared and DNP-prepared nurse practitioners sit for the identical national board exam and hold the identical NP credential, so a DNP doesn't expand what you can do clinically. The DNP (3 to 4 years full-time from a BSN) makes sense if you're aiming for leadership, faculty, or health-systems roles.
How do you become a CRNA, and how long does it take?
Become an RN with a BSN, build real critical-care experience (usually in an ICU), then complete a doctoral nurse anesthesia program of 14 to 36 months. At the end you sit for the NBCRNA National Certification Exam: 100 to 170 questions over 3 hours, $1,310, with up to 4 attempts in a 2-year window.
Is it normal to fail the NCLEX on the first try?
It happens more than most people expect, but the odds shift a lot on a retest. The most recent data shows an 86.7% first-time pass rate versus only 52.7% on a repeat attempt, so a real study plan before retesting matters more than simply trying again.
Is nursing school harder to get into now because of the shortage?
In a way, yes, but not for the reason most people assume. It's not that fewer people want to become nurses. AACN reports 92,672 qualified applicants were turned away from nursing programs in 2025 because schools didn't have enough faculty, clinical sites, or classroom space, not because of a lack of interest.
Should I go straight into a specialty as a new grad, or start in med-surg first?
Honestly, this is still a genuine debate among nurse managers, not a settled rule. Some prefer at least a year of med-surg experience as proof you can handle a high-volume, fast-changing environment. Others will hire a strong new grad with real passion for a specialty directly into it, especially where a solid residency program exists. Both are legitimate paths, and the right answer depends on the specific program.
