Becoming a nurse takes anywhere from a few weeks to eight or more years, depending on which type of nurse you want to be. A certified nursing assistant can finish training in as little as four to six weeks, while a registered nurse needs two to four years of education, and an advanced practice nurse adds another two to four years on top of that. Here’s what each path looks like in practice.
Certified Nursing Assistant: 4 to 12 Weeks
If you want to start working in healthcare as quickly as possible, becoming a CNA is the fastest route. California, for example, requires just 160 hours of training: 60 hours of classroom instruction and 100 hours of supervised clinical practice. Most programs run four to twelve weeks depending on whether you attend full-time or part-time. After completing the program, you’ll take a state competency exam before you can start working.
CNAs provide hands-on patient care like helping with bathing, dressing, feeding, and taking vital signs. The role is physically demanding and the pay is lower than other nursing positions, but it gets you into the field fast and gives you clinical experience that’s valuable if you decide to pursue further education later.
Licensed Practical Nurse: 12 to 18 Months
Licensed practical nurses (called licensed vocational nurses in California and Texas) complete programs that typically run 12 to 18 months. These programs are offered at community colleges and vocational schools and include both classroom coursework and clinical rotations. After graduating, you’ll need to pass the NCLEX-PN licensing exam.
LPNs can do more than CNAs, including administering medications, inserting catheters, and monitoring patients under the supervision of a registered nurse or physician. For people who want a meaningful clinical role without committing to a four-year degree, this is a practical middle ground. It also opens the door to bridge programs that let you advance to RN or BSN status later.
Registered Nurse: 2 to 4 Years
Most people searching “how long does it take to become a nurse” are thinking about becoming a registered nurse. There are two main educational paths, and both qualify you to take the same licensing exam.
Associate Degree in Nursing (ADN): 2 Years
An ADN is a two-year program typically offered at community colleges. It focuses on core nursing skills and clinical training without the broader liberal arts coursework of a bachelor’s program. Some schools offer accelerated versions that can be completed in about 18 months. Community college tuition makes this the more affordable option, and you’ll be eligible for RN licensure as soon as you graduate and pass the exam.
The catch: many hospitals, especially large medical centers and those pursuing Magnet designation, now prefer or require a bachelor’s degree. An ADN will get you working sooner, but you may find yourself completing a bridge program within a few years to stay competitive.
Bachelor of Science in Nursing (BSN): 4 Years
A BSN is a four-year undergraduate degree at a college or university. It covers the same clinical foundations as an ADN but adds coursework in leadership, public health, research, and community nursing. This broader preparation opens more doors from the start, including positions in management, education, and specialized units that often list a BSN as a minimum requirement.
Those four years include a significant chunk of prerequisite coursework. Before you even enter the core nursing program, you’ll typically need to complete courses in anatomy, physiology, microbiology, chemistry, statistics, psychology, nutrition, and English composition. Most nursing schools require a C or higher in every prerequisite, with a minimum cumulative GPA of 3.0. At many universities, students spend their first two years on prerequisites and general education, then enter the nursing program for their final two years of intensive clinical training.
The Prerequisites Add Up
One thing that surprises many prospective nursing students is how much time prerequisites can take. The science requirements alone, including anatomy, physiology, microbiology, and chemistry with labs, can easily fill three to four semesters if you’re taking them alongside other general education courses. Some programs require that specific courses like anatomy, physiology, and microbiology be completed the semester before you apply.
If you’re starting from scratch at a community college before transferring into a BSN program, plan for at least 60 credit hours of undergraduate coursework before admission. Students who already have college credits in biology or chemistry will move through this phase faster, but for most people, prerequisites represent one to two years of work before the nursing-specific curriculum even begins.
Accelerated BSN: 12 to 16 Months
If you already hold a bachelor’s degree in another field, an accelerated BSN program lets you skip the general education courses and dive straight into nursing. These programs are intense. The University of Florida’s accelerated BSN, for instance, starts each May and runs through four back-to-back semesters, finishing the following August, roughly 16 months total.
Other accelerated programs can be completed in as little as 12 months. The tradeoff is pace: these are full-time commitments with heavy course loads and clinical hours packed into a compressed timeline. Working during an accelerated program is difficult to impossible. But for career changers, this is often the fastest realistic path to becoming an RN.
RN-to-BSN Bridge: 12 to 24 Months
Nurses who earned an ADN and are already working as RNs can complete a bridge program to earn their BSN. Many of these programs are offered online and designed around the schedules of working nurses. Full-time students can finish in as few as 12 months by taking two or more courses per eight-week session. Part-time students who take one course at a time will need longer, typically 18 to 24 months.
This path has become increasingly common as more employers push for BSN-prepared nurses. You continue working and earning your RN salary while completing the degree, which makes it financially practical even if it extends your total timeline.
LPN-to-BSN Bridge: About 2 Years
Licensed practical nurses who want to jump directly to a BSN can do so through bridge programs that give credit for prior LPN education and clinical experience. Ohio State University’s LPN-to-BSN program, for example, takes two years of full-time study including summers. These programs are less widely available than RN-to-BSN options, so you may need to relocate or find an online program.
Advanced Practice Nurse: 6 to 8+ Years Total
Nurse practitioners, nurse midwives, nurse anesthetists, and clinical nurse specialists all require graduate education beyond the BSN. A Master of Science in Nursing (MSN) typically takes two to three additional years. A Doctor of Nursing Practice (DNP), which is increasingly becoming the expected credential for advanced practice roles, requires a minimum of 1,000 clinical hours spread across master’s and doctoral coursework.
NYU’s DNP program, as one example, requires at least 36 credits and 400 clinical hours at the doctoral level alone, with many students completing the degree part-time while working. From start to finish, becoming a nurse practitioner with a DNP means roughly six to eight years of post-secondary education, though the timeline stretches further if you attend part-time or take breaks between degrees.
Licensing Adds a Few More Weeks
No matter which path you take, you can’t practice until you pass your licensing exam. For RNs, that’s the NCLEX-RN. After your nursing program submits your paperwork, you’ll receive authorization to test, usually within about two weeks. You then schedule your exam and must complete it within the dates listed on your authorization.
Results typically arrive within about four weeks by mail, though many states offer quick unofficial results online within 48 hours for a small fee. From graduation to official license in hand, expect roughly one to two months. Some new graduates also enter nurse residency programs at their first hospital, which run up to a year and help bridge the gap between school and independent practice. Mayo Clinic’s residency program, for instance, is designed to be completed within the first 12 months of employment.
Total Timelines at a Glance
- CNA: 4 to 12 weeks
- LPN: 12 to 18 months
- RN with ADN: 2 to 3 years (including prerequisites)
- RN with BSN: 4 years
- Accelerated BSN (with prior degree): 12 to 16 months
- RN-to-BSN bridge: 12 to 24 months on top of ADN
- Nurse practitioner (MSN): 6 to 7 years total
- Nurse practitioner (DNP): 7 to 8+ years total
Your actual timeline depends on whether you attend full-time or part-time, how quickly you finish prerequisites, and whether your program has a waitlist. Competitive nursing programs at state universities sometimes have wait times of one to two semesters just to begin, so factor that into your planning as well.
