Becoming a registered nurse takes two to four years depending on the degree you choose, followed by passing a national licensing exam. The two main educational routes are an Associate Degree in Nursing (ADN), which takes about two years, and a Bachelor of Science in Nursing (BSN), which takes four. Both qualify you to sit for the same licensing exam and work as an RN, but they open different doors over the course of your career.
Choose Your Degree Path
The first decision you’ll make is which nursing degree to pursue. An ADN is a two-year program typically offered at community colleges, with some accelerated versions finishing in 18 months. The curriculum covers prerequisites like chemistry, anatomy, biology, and psychology, then moves into nursing-specific courses: fundamentals of nursing, medical-surgical nursing, pediatric nursing, psychiatric nursing, and community health.
A BSN is a four-year undergraduate program at a college or university. It covers the same clinical skills as an ADN but adds coursework in public health, nursing ethics, pathophysiology, and theoretical nursing concepts. That broader foundation matters for career advancement: a BSN is required for admission to any graduate nursing program, and many hospitals now prefer or require it when hiring. BSN holders also earn higher salaries on average and have a slight edge on the licensing exam, with an 82.3% first-attempt pass rate compared to 77.9% for ADN holders.
If you already have a bachelor’s degree in a non-nursing field, some schools offer accelerated BSN transfer programs that compress the nursing curriculum into roughly two years of full-time study, including summer sessions. These programs require you to have completed around 52 general education credits beforehand, with prerequisite science courses like microbiology, chemistry, and anatomy and physiology earning a C or better.
Complete Your Prerequisites
Before you can enter a nursing program, you’ll need to finish a set of prerequisite courses. The exact list varies by school, but the core sciences are consistent: anatomy and physiology, microbiology, chemistry, and biology. Most programs also require psychology, English composition, and general education credits in areas like history and government. Some universities require statistics or nutrition as well.
If you’re pursuing an ADN, many of these prerequisites are built into the two-year program at your community college. For a BSN, you’ll typically complete them during your first two years of college before entering the upper-division nursing courses. Either way, strong grades in your science prerequisites matter. Nursing programs are competitive, and admissions committees weigh those courses heavily.
Clinical Rotations
Every nursing program includes hands-on clinical training in real healthcare settings. The number of required clinical hours varies by state, since each state’s board of nursing sets its own minimums. During your rotations, you’ll cycle through several types of care environments: long-term care facilities, acute care hospitals, medical-surgical clinics, pediatrics, labor and delivery, mental health facilities, and community health settings.
Clinicals are where the classroom content becomes real. You’ll work under the supervision of experienced nurses, practicing patient assessments, administering medications, and learning to communicate with patients and healthcare teams. These rotations also help you figure out which area of nursing interests you most, since you’ll get exposure to a wide range of specialties before you graduate.
Pass the NCLEX-RN Exam
After graduating from an accredited nursing program, your next step is passing the National Council Licensure Examination for Registered Nurses, known as the NCLEX-RN. This is the standardized test that every state requires for RN licensure.
The exam covers four broad areas: safe and effective care environments (including patient safety and infection control), health promotion and maintenance, psychosocial integrity, and physiological integrity (covering everything from basic comfort care to medication administration and managing acute conditions). Questions come in multiple formats, including standard multiple-choice, case studies, and items with charts, tables, or graphics.
The NCLEX-RN uses a computer-adaptive format, meaning the difficulty of each question adjusts based on how you answered the previous one. The test ends when the computer reaches 95% confidence that your ability is clearly above or below the passing standard. If that threshold isn’t reached, the exam continues up to the maximum number of questions. There’s no fixed passing percentage or score. The passing standard is set every three years by the National Council of State Boards of Nursing and represents the minimum competency needed for safe entry-level practice.
Apply for State Licensure
Once you pass the NCLEX-RN, you apply for licensure through your state’s board of nursing. Every state requires a fingerprint-based criminal background check as part of this process. In most cases, you’ll schedule an electronic fingerprint scan through a designated vendor. If your record is clean, results typically reach the board within 24 to 48 hours. If there’s a criminal history on file, the review can take 30 days or longer, since the board must evaluate the record before making a licensing decision.
Your license is issued by the state where you live, but 43 states and territories now participate in the Nurse Licensure Compact (NLC). If your home state is a compact member, you can apply for a multistate license that lets you practice in any other compact state without getting a separate license. If you move to a different compact state, you have 60 days to apply for licensure in your new state of residence. States outside the compact require their own individual license applications.
Timeline From Start to Practice
The fastest route is an ADN, which can put you in practice in roughly two and a half years: two years for the degree, then a few weeks to months for exam scheduling, testing, and license processing. A BSN adds about two more years of school on the front end, putting total time closer to four and a half years. Accelerated BSN programs for students with prior college credits fall somewhere in between.
After you’re licensed and working, the career can keep expanding. Nurse practitioners, certified nurse-midwives, and other advanced practice roles require a graduate degree and typically take six to ten years of combined education and experience. Certified registered nurse anesthetists need a doctoral degree and critical care experience, adding up to eight to ten years total.
Salary and Job Outlook
The median annual salary for registered nurses was $93,600 as of May 2024. Employment in the field is projected to grow 5% from 2024 to 2034, which is faster than the average for all occupations. That growth is driven by an aging population, increasing rates of chronic conditions, and ongoing demand across hospitals, outpatient centers, and home health settings. Nurses with a BSN generally have more job options and higher earning potential, particularly at large hospital systems and academic medical centers that increasingly treat the bachelor’s degree as a baseline requirement.
