Getting your Bachelor of Science in Nursing (BSN) typically requires completing around 120 credit hours of coursework, including general education, science prerequisites, and hands-on clinical rotations. The path you take depends on where you’re starting: a high school graduate, someone with a degree in another field, a working LPN, or a registered nurse with an associate degree. Each route has a different timeline, cost, and set of requirements.
The Traditional Four-Year BSN
The most common route is entering a BSN program straight out of high school or as a first-time college student. These programs take four years of full-time study and require a minimum of 120 credit hours to graduate. The first two years focus heavily on general education and science prerequisites: anatomy, physiology, microbiology, chemistry, statistics, psychology, and sociology. The final two years shift to nursing-specific courses and clinical rotations in hospitals, clinics, and community health settings.
To get in, most programs require a minimum GPA (often 2.5 to 3.0 in prerequisite courses) and a standardized entrance exam. The most widely used is the TEAS (Test of Essential Academic Skills). Competitive programs recommend scoring at least 60% on the TEAS, though higher scores improve your chances since nursing programs often receive far more applicants than they can accept. Some schools allow you to retake the exam, but many cap it at two attempts.
Cost varies significantly. Public universities charge roughly $90,000 to $120,000 or more for a full four-year BSN when you factor in tuition, fees, books, and supplies. Private institutions range from $120,000 to $250,000 or higher. In-state tuition at a public school is the most affordable option for most students, and community college coursework for your first two years of prerequisites can reduce that total further.
Accelerated BSN for Career Changers
If you already hold a bachelor’s degree in any field, an accelerated BSN (ABSN) lets you skip the general education courses and focus entirely on nursing. These programs compress the nursing curriculum into 12 to 18 months of intensive, full-time study. They’re designed for career changers and are not compatible with working while enrolled.
You’ll need to complete science prerequisites before applying, and programs are strict about them. Typical requirements include:
- Human anatomy with lab (minimum 4 units)
- Human physiology with lab (minimum 4 units)
- Microbiology with lab (minimum 4 units)
- Chemistry with lab (minimum 3 units)
- Statistics (minimum 3 units)
- Introductory psychology
- Introductory sociology or cultural anthropology
Most programs require a B or higher in science courses, and those courses must have been completed within the last five years. If you took anatomy a decade ago, you’ll likely need to retake it. Since you already hold a bachelor’s degree, requirements like English composition and critical thinking are typically waived. Completing the prerequisites at a community college before applying is a common and cost-effective strategy, though it may add six months to a year to your overall timeline.
RN-to-BSN for Working Nurses
Registered nurses who entered practice with an associate degree in nursing (ADN) or a hospital diploma can upgrade to a BSN through an RN-to-BSN program. These programs are widely available online, making them practical for nurses who want to keep working while they study.
Your existing nursing education counts for a significant chunk of the degree. At many programs, around 32 credits transfer in from your ADN coursework, and you complete roughly 30 additional nursing credits at the university level. The remaining credits come from general education courses you may have already finished. Most RN-to-BSN programs take 12 to 18 months for full-time students, or two to three years part-time.
The coursework focuses on areas not typically covered in an ADN: nursing research, evidence-based practice, community and public health nursing, leadership, and healthcare policy. You won’t repeat the bedside clinical skills you already have.
LPN-to-BSN Bridge Programs
Licensed practical nurses can also bridge directly to a BSN without first becoming an RN separately. These programs award transfer credit for your LPN training (typically around 18 credits) and then move you through the full BSN curriculum. The total requirement is still 120 credits, so the timeline is shorter than a traditional four-year program but longer than an RN-to-BSN track.
Admission requires a current LPN license in good standing, a minimum GPA of 2.5 from your LPN program, and passing scores on bridge exams that test your existing nursing knowledge. You’ll also need letters of recommendation, usually one from a current employer and one from a former instructor. These programs blend online coursework with in-person clinicals and can take two to three years depending on how many general education courses you’ve already completed.
Why Hospitals Increasingly Prefer a BSN
The push toward BSN-prepared nurses isn’t just academic preference. A landmark study of 510 hospitals and over 20,000 nurses at the University of Pennsylvania found that every 10% increase in the proportion of BSN-educated nurses on staff led to a 5.5% decrease in surgical patient mortality. Hospitals where 80% of nurses held a BSN had mortality rates roughly 25% lower than hospitals where only 30% did.
These numbers have driven real policy changes. New York State now requires newly licensed RNs to earn a BSN or higher within 10 years of licensure, with regulations clarified as recently as April 2026. Many major hospital systems, particularly Magnet-designated facilities, already require or strongly prefer BSN-prepared nurses for hiring and promotion. Even in states without legal mandates, a BSN opens doors to leadership roles, specialty certifications, and graduate programs that an ADN alone does not.
Passing the NCLEX-RN After Graduation
Earning your BSN doesn’t automatically make you a registered nurse. You still need to pass the NCLEX-RN, the national licensure exam. The process involves two separate registrations: one with Pearson VUE (the testing company) and one with the board of nursing in the state where you want to practice.
Your nursing school will verify your education to the state board. Once both registrations are processed, the state board issues an Authorization to Test (ATT), which typically arrives two to four weeks after graduation. You then schedule your exam through Pearson VUE. The NCLEX-RN is a computerized adaptive test, meaning it adjusts difficulty based on your answers, and results are usually available within 48 hours.
If you plan to work in multiple states, many states now participate in the Nurse Licensure Compact, which allows you to hold a single multistate license rather than applying separately in each state. Check whether your home state participates before choosing between a single-state and multistate license.
Choosing the Right Path
Your best route to a BSN depends on your current credentials, your financial situation, and how quickly you need to finish. The traditional four-year program works well for students entering college for the first time and offers the most clinical exposure. The accelerated BSN is the fastest option if you already have a bachelor’s degree, but it’s demanding and often more expensive per credit hour. RN-to-BSN programs offer the most flexibility for working nurses, and the online format means geography isn’t a limiting factor. LPN-to-BSN bridges make sense if you want to skip the intermediate step of earning an ADN separately.
Whichever path you choose, verify that the program holds accreditation from either the Commission on Collegiate Nursing Education (CCNE) or the Accreditation Commission for Education in Nursing (ACEN). Graduating from an unaccredited program can create problems with licensure, employer recognition, and admission to graduate school later on.
