Becoming a nurse typically takes one to four years depending on the level of nursing you pursue. The fastest entry point is a Licensed Practical Nurse certificate, which takes about a year, while a full Bachelor of Science in Nursing takes four years. Each path leads to a different scope of practice, salary range, and set of career options.
The Three Main Levels of Nursing
Nursing isn’t a single career path. It’s a ladder with distinct entry points, and understanding the differences upfront will save you time and money.
Licensed Practical Nurse (LPN): Requires a high school diploma and completion of an accredited practical nursing certificate program, typically one year long. LPNs provide basic patient care under the supervision of registered nurses and physicians. You’ll need to pass the NCLEX-PN exam to get licensed.
Registered Nurse (RN): The most common nursing role. You can qualify through either a two-year Associate Degree in Nursing (ADN) or a four-year Bachelor of Science in Nursing (BSN). Both paths require passing the NCLEX-RN exam. The median annual wage for registered nurses was $93,600 in May 2024, and employment is projected to grow 5 percent from 2024 to 2034.
Advanced Practice Registered Nurse (APRN): This includes nurse practitioners, nurse anesthetists, and clinical nurse specialists. APRNs must hold at least a master’s degree in nursing, and some earn a Doctor of Nursing Practice. They also complete hundreds of additional clinical training hours and pass a national board certification exam in their specialty.
Prerequisites You’ll Need Before Nursing School
Nursing programs don’t start with nursing courses. You’ll spend your first year or more completing science-heavy prerequisites, and most programs set a high bar for grades. At many schools, you need a B-minus or better on your first attempt in each prerequisite course.
The core prerequisites for a BSN program typically include:
- Human Anatomy and Physiology I and II, both with labs
- Microbiology with lab
- Introduction to Statistics
- Human Growth and Development
- Human Nutrition
- A psychology or sociology course
- An additional science course (chemistry, biology, or physics)
On top of these, you’ll complete general education requirements in English composition, humanities, and math. ADN programs at community colleges require many of the same science prerequisites but fewer general education credits overall. If your grades in anatomy or microbiology are weak, that’s often the biggest barrier to admission, since these courses are competitive and heavily weighted in application scoring.
How Much Nursing School Costs
The financial gap between the two RN pathways is significant. An ADN at a public school runs between $6,000 and $20,000 in tuition. A four-year BSN program ranges from $40,000 to over $200,000 depending on whether you attend a public university, private institution, or out-of-state school.
Both degrees let you sit for the same NCLEX-RN licensing exam, and both produce registered nurses. However, many hospitals now prefer or require a BSN for hiring, and some employers offer tuition reimbursement for ADN-prepared nurses who complete a BSN later through an online RN-to-BSN bridge program. Starting with an ADN and bridging to a BSN is a common strategy for keeping costs down while getting into the workforce faster.
What Clinical Rotations Look Like
Clinical rotations are the hands-on portion of your nursing education, where you work with real patients in hospitals, clinics, long-term care facilities, and community health settings. The required hours vary by state, as each state’s board of nursing sets its own minimums. Expect to spend several hundred hours in clinical settings before graduation.
Clinicals typically begin in your second year and rotate through different specialties: medical-surgical nursing, pediatrics, obstetrics, mental health, and critical care. You’ll be supervised by a clinical instructor and assigned a small number of patients to care for during each shift. These rotations are where classroom knowledge becomes real, and they’re also where many students discover which specialty they want to pursue after graduation.
Passing the NCLEX Licensing Exam
Every nursing graduate must pass the NCLEX to practice. The NCLEX-PN is for LPNs, and the NCLEX-RN is for registered nurses. Registration costs $200 for candidates seeking U.S. licensure, plus any fees your state board charges for the license application itself.
The NCLEX-RN uses computerized adaptive testing, meaning the exam adjusts its difficulty based on your answers in real time. It covers safe patient care, clinical judgment, pharmacology, and health promotion. Most nursing programs build NCLEX preparation into the final semester, and many students also use commercial review courses or question banks to prepare. First-time pass rates vary by program, so checking a school’s NCLEX pass rate before enrolling is a smart move.
State Licensing and the Nurse Compact
Your nursing license is issued by a specific state, but you don’t necessarily need a separate license for every state where you want to work. The Nurse Licensure Compact (NLC) currently includes 43 jurisdictions. If your primary state of residence is a compact member, your single license allows you to practice in all other compact states without additional applications.
If you live in a non-compact state or want to work in one, you’ll need to apply for licensure in that specific state. Each state has its own application process, fees, and background check requirements. Maintaining your license requires continuing education. California, for example, requires 30 contact hours of continuing education every two years for renewal. Other states set their own requirements, so you’ll need to check with your state board.
The Accelerated Path for Career Changers
If you already hold a bachelor’s degree in any field other than nursing, you can enter an Accelerated BSN (ABSN) program. These intensive, full-time programs compress the nursing curriculum into roughly 15 months. You’ll transfer in your general education and prerequisite credits from your previous degree, then focus entirely on nursing coursework and clinicals.
ABSN programs are demanding. You’re covering the same clinical and didactic material as a traditional four-year student in a fraction of the time, which means classes run year-round with little break. You’ll still need to complete the same science prerequisites (anatomy, microbiology, etc.) before starting, so factor those in if your original degree didn’t include them. After graduating, you take the NCLEX-RN just like any other BSN graduate.
Moving Up After Your RN License
Many nurses use their RN as a starting point rather than a final destination. The most common next step is becoming a nurse practitioner or other APRN, which requires a master’s degree at minimum. Some nurses pursue a Doctor of Nursing Practice for the highest level of clinical training. APRN programs typically require at least one to two years of clinical RN experience before admission, though requirements vary by school.
Specialization doesn’t always require a graduate degree. RNs can earn certifications in areas like critical care, oncology, emergency nursing, or wound care through professional organizations. These certifications require a combination of clinical hours in the specialty and a certification exam. They won’t change your license type, but they can open doors to higher-paying, more specialized positions.
