The core difference between a registered nurse (RN) and a licensed practical nurse (LPN) is scope of practice. RNs independently assess patients, create care plans, and make clinical decisions. LPNs carry out nursing tasks under the supervision of an RN or physician. This distinction shapes everything else: how long you’re in school, what exam you take, where you work, and what you earn.
Education and Time in School
LPN programs are the faster path into nursing. Most take about one year and are offered at community colleges, technical schools, or hospitals. The curriculum covers fundamental nursing skills, basic pharmacology, and patient care, with clinical hours built in.
Becoming an RN requires more education, but you have options. An associate degree in nursing (ADN) typically takes two to three years at a community college. A bachelor of science in nursing (BSN) takes four years at a university. There’s also a diploma route through hospital-based programs, which runs about two years but doesn’t result in a college degree. All three paths lead to RN licensure, though many hospitals now prefer or require a BSN for hiring.
The Licensing Exams
Both roles require passing a national licensing exam before you can practice, but the two tests differ in length and focus. The NCLEX-PN (for LPNs) has between 85 and 205 questions with a five-hour time limit. The NCLEX-RN has between 75 and 265 questions with a six-hour time limit. Both use computerized adaptive testing, meaning the difficulty adjusts based on your answers, and the computer stops when it’s 95% certain you’ve passed or failed.
The content reflects each role’s responsibilities. The NCLEX-PN emphasizes care coordination, data collection, basic comfort measures, and safety protocols. The NCLEX-RN leans harder into physical sciences, patient assessment, management of care, and ethical and legal scenarios. The RN exam also tests knowledge of advanced therapies like IV administration, blood transfusions, and central venous access.
What Each Role Does on the Job
The clearest way to understand the difference is through the nursing process: assessment, planning, implementation, and evaluation. RNs own that process. They perform comprehensive initial assessments, interpret clinical data, identify patient needs, set goals, and build care plans. They also direct the work of LPNs and unlicensed staff, making sure delegated tasks are completed correctly.
LPNs contribute to each step but don’t lead it. They collect patient data and recognize changes in a patient’s condition, but it’s not within their scope to perform a comprehensive initial assessment or interpret clinical data independently. They help develop and modify care plans but can’t create them. They carry out nursing interventions, provide patient and family education, and document responses to treatment, all under the direction of an RN or licensed provider.
One practical example: IV therapy. RNs administer IV medications, blood products, and manage central lines as a standard part of their training. LPNs in many states can perform IV therapy only after completing additional post-graduation coursework. In Florida, for instance, that means a minimum 30-hour course followed by supervised clinical practice, with competency verified in writing by an RN. Some states don’t allow LPNs to perform IV therapy at all, and the rules around central and PICC lines are even more restrictive.
Supervision and Autonomy
RNs practice independently within their scope. They assess patients, make clinical judgments, and adjust care plans on their own authority. They also supervise LPNs and delegate tasks to other staff.
LPNs have what’s formally called a “supervised practice.” In Oregon, for example, state rules specify that LPNs work at the clinical direction and under the clinical supervision of an RN or a licensed independent practitioner (such as a physician or nurse practitioner). This means an LPN selects nursing interventions that have already been established by the RN or are consistent with the physician’s plan. If an LPN identifies a safety concern or a change in a patient’s condition, they take immediate action but then report to the supervising RN. LPNs can assign tasks to nursing assistants and other LPNs, but they evaluate the effectiveness of those assignments and report back to the RN overseeing care.
The supervision requirement doesn’t mean an RN is standing over an LPN’s shoulder at all times. In many settings, particularly long-term care facilities, LPNs work with significant day-to-day responsibility. But the legal accountability for the care plan and clinical decision-making sits with the RN.
Where Each Role Typically Works
About 60% of RNs work in hospitals, according to Bureau of Labor Statistics data. Beyond that, RNs practice in a wide range of settings: outpatient clinics, schools, correctional facilities, occupational health offices, home health, and even cruise ships. The breadth of RN training opens doors to nearly every corner of healthcare.
LPNs are commonly found in assisted living facilities, nursing homes, physician offices, and hospitals. Long-term care is a particularly large employer of LPNs, since these settings rely heavily on the kind of ongoing, hands-on patient care that falls squarely within the LPN scope. You’ll also find LPNs in home health, rehabilitation centers, and outpatient clinics.
Salary Differences
The pay gap between the two roles is significant. As of May 2023, the median annual wage for LPNs was $59,730, or about $28.72 per hour, according to the Bureau of Labor Statistics. RNs earn considerably more. While the most current BLS figure for RNs wasn’t captured in the same dataset, the median has consistently hovered around $86,000 to $90,000 in recent years, reflecting the additional education, broader scope, and higher level of clinical responsibility.
Geography, specialty, and work setting all influence pay for both roles. Nurses in metropolitan areas and states with higher costs of living tend to earn more. Hospital-based positions generally pay better than long-term care or outpatient clinic roles.
Job Outlook
Demand for RNs is projected to grow 5% from 2024 to 2034, faster than the average for all occupations. That translates to roughly 189,100 openings for registered nurses each year over the decade, driven by retirements, an aging population, and expanding healthcare needs. LPN demand remains steady as well, particularly in long-term care and home health, though the strongest growth and the widest range of opportunities tend to favor RNs.
Moving From LPN to RN
If you start as an LPN, you don’t have to go back to square one to become an RN. LPN-to-RN bridge programs are designed specifically for this transition and typically take one to two years, depending on your prior coursework and experience. Some programs offer accelerated schedules, while others run part-time for working nurses. You may receive credit for previous education, which shortens the timeline. Clinical rotations are part of the program and can add several months.
Many nurses use the LPN role as a deliberate stepping stone. You start earning a paycheck and gaining clinical experience within about a year, then move into an RN bridge program once you’re ready. It’s a practical route, especially if you need to work while completing your education. After finishing the bridge program, you take the NCLEX-RN and, upon passing, practice as a registered nurse with the full scope that comes with it.
