Becoming a registered nurse (RN) requires completing an approved nursing program and passing a national licensing exam called the NCLEX-RN. The full process takes two to four years depending on the degree path you choose, and most programs require science prerequisites before you can even apply. Here’s what each step looks like.
Choose Between a Two-Year and Four-Year Degree
Two educational paths lead to RN licensure. An Associate Degree in Nursing (ADN) is a two-year program typically offered at community colleges, with some accelerated options finishing in 18 months. A Bachelor of Science in Nursing (BSN) is a four-year program at a college or university that provides broader clinical experience and more in-depth coursework in areas like public health, leadership, and research.
Both degrees qualify you to sit for the same licensing exam and work as an RN. The practical difference comes down to hiring preferences and long-term career options. Many hospitals, especially those pursuing Magnet designation, prefer or require BSN-prepared nurses. If you start with an ADN, you can complete an RN-to-BSN bridge program later while working.
Complete Prerequisite Courses
Before starting a nursing program, you’ll need to finish several science and math courses. While exact requirements vary by school, the standard list includes:
- Anatomy and Physiology I and II (two semesters, at least 3 credits each)
- Chemistry with lab (must be at least 4 credits; organic chemistry and biochemistry typically don’t count)
- Microbiology
- Statistics
- Nutrition (human nutrition or nutrition science preferred)
- Developmental psychology across the lifespan (intro psych, abnormal psych, and child psych usually don’t satisfy this)
Most programs require a C or better in every prerequisite. Many schools also impose a 10-year expiration on science courses, so if you took anatomy a decade ago, you may need to retake it. These prerequisites can usually be completed at a community college, even if you plan to apply to a university BSN program. Chemistry with a lab component generally must be taken in person, though other prerequisites are often accepted in an online format.
What Happens During Nursing School
Nursing programs blend classroom learning with hands-on clinical rotations in hospitals, clinics, and other healthcare settings. At the University of Colorado’s BSN program, for example, students complete 765 hours of face-to-face clinical training. Rotations cycle through several specialties so you develop a broad skill set before graduating.
Typical clinical rotations include medical-surgical nursing (the backbone of hospital care), pediatrics, obstetrics covering labor and delivery, mental health in both inpatient and outpatient settings, and community health in outpatient clinics. Rotation lengths vary. Mental health and obstetrics rotations can be as short as 48 hours (about four 12-hour shifts), while a senior practicum, where you work closely with a preceptor in your final semester, can run 180 hours or more.
Clinical hours are physically and emotionally demanding. You’ll work 12-hour shifts, document patient assessments, administer medications under supervision, and learn to think on your feet. This is where most students say nursing “clicks,” because the skills you’ve been studying in a classroom suddenly apply to a real person in front of you.
Pass the NCLEX-RN
After graduating from an approved program, you’ll apply for licensure through your state board of nursing and register to take the NCLEX-RN. This is a computerized adaptive test, meaning the difficulty of each question adjusts based on how you answer the previous one. The exam measures whether you can safely practice as an entry-level nurse.
The current passing standard is set at 0.00 logits, a statistical measure that essentially asks whether your demonstrated ability meets the minimum competency threshold. In practical terms, the test keeps serving you questions until it’s statistically confident you’re above or below that line. You won’t receive a numerical score. You’ll simply pass or fail.
Most nursing graduates take the NCLEX within a few weeks of finishing their program, when the material is still fresh. If you don’t pass on the first attempt, you can retake it after a 45-day waiting period.
Understand State Licensure and the Nurse Compact
Your RN license is issued by the state where you apply, and each state has its own board of nursing with slightly different requirements. One major advantage for nurses today is the Nurse Licensure Compact (NLC). Currently 43 states and jurisdictions participate, allowing nurses who hold a multistate license in one compact state to practice in any other compact state without obtaining additional licenses.
To qualify for a multistate license, you need to live in a compact state and meet that state’s licensure requirements. If you move to a different compact state, you have 60 days to apply for licensure in your new home state. If your state isn’t part of the compact, you’ll need to apply for a separate license in each state where you want to work.
Accelerated Programs for Career Changers
If you already hold a bachelor’s degree in another field, an accelerated BSN program lets you earn your nursing degree in roughly 15 months of full-time study. These programs are intensive, running four consecutive semesters with no summer break, but they cover the same clinical and classroom content as a traditional BSN.
Admission requires a completed bachelor’s degree from an accredited institution, strong academic performance, and the same science prerequisites as traditional programs. You’ll still need anatomy and physiology, chemistry with a lab, microbiology, statistics, nutrition, and developmental psychology. Many career changers spend a year completing prerequisites at a community college before starting the accelerated program itself, so plan for a total timeline of about two to two and a half years from start to licensure.
Bridge Programs for LPNs
Licensed practical nurses (LPNs) and licensed vocational nurses (LVNs) can transition to RN status through bridge programs that give credit for prior nursing education and experience. These programs are offered at both the ADN and BSN level. At California State University, Fullerton, for instance, the LVN-to-BSN pathway waives certain introductory nursing courses, though the total credit requirement (120 units) stays the same. The time savings comes from skipping foundational courses you’ve already mastered, which can shave several semesters off the standard timeline.
Paths for Internationally Educated Nurses
If you completed nursing education outside the United States, you’ll need to have your credentials evaluated before applying for state licensure. CGFNS International (now TruMerit) is the primary organization that handles this process, offering credential evaluation, verification, and a visa screening service required for employment-based immigration. Requirements vary significantly by state, but you can generally expect to provide proof of your nursing education, pass an English proficiency exam, and eventually take the NCLEX-RN just like domestically trained nurses.
Salary and Job Outlook
The median annual wage for registered nurses was $93,600 as of May 2024, according to the Bureau of Labor Statistics. That figure varies widely by specialty, location, and experience. Nurses in metropolitan areas and those working in critical care, emergency, or surgical settings tend to earn above the median.
Employment of registered nurses is projected to grow 5 percent from 2024 to 2034, faster than the average for all occupations. An aging population, increasing rates of chronic conditions, and ongoing retirements in the nursing workforce all drive steady demand. Specialties like home health, outpatient care, and telehealth nursing are expanding particularly fast as healthcare shifts away from traditional hospital settings.
