Yes, a Bachelor of Science in Nursing (BSN) is an undergraduate degree. It sits at the same academic level as any other bachelor’s degree, such as a B.A. in English or a B.S. in Biology, and it typically requires four years of full-time study and a minimum of 120 credit hours to complete.
What the BSN Covers
A BSN program is split into two broad phases. The first two years focus on general education and prerequisite courses: English composition, statistics, psychology, sociology, chemistry, human anatomy and physiology, and nutrition. These are the same types of foundational courses you would take in most other undergraduate programs.
The upper division, usually the final two years, shifts to professional nursing coursework and supervised clinical rotations. This is where you learn pharmacology, pathophysiology, nursing informatics, patient assessment, community health, and leadership. Clinical hours put you in hospitals, clinics, and other healthcare settings to practice hands-on patient care under supervision. Programs typically structure the full curriculum across eight semesters.
How a BSN Differs From an ADN
You can also become a registered nurse by earning an Associate Degree in Nursing (ADN), which is a two-year community college credential. Both ADN and BSN graduates sit for the same licensing exam, the NCLEX-RN, and both can work as registered nurses. The practical difference shows up after you start working.
BSN-prepared nurses typically have a higher salary ceiling and more options for career advancement. Leadership positions like charge nurse, nurse manager, or clinical educator frequently require a bachelor’s degree. The same is true for specialty roles in critical care, pediatrics, and oncology. Magnet-recognized hospitals, which are considered leaders in nursing quality, strongly encourage or require a BSN as a standard for practice. Many large healthcare systems prefer BSN-prepared nurses even when it is not a formal requirement, and some hospitals ask new hires with an ADN to sign agreements committing to complete a BSN within a set timeframe, often with tuition reimbursement to help.
Growing Pressure to Hold a BSN
The nursing field has been moving toward making the BSN a baseline expectation. New York became the first state to enact what is known as a “BSN-in-10” law, signed in December 2017. Under that law, newly licensed registered nurses who enter the field with an associate degree or diploma must earn a BSN within 10 years of initial licensure. The requirement applies to nurses licensed after the law took effect in 2019; those already licensed or enrolled in ADN programs before that date are exempt. Other states have introduced similar bills, though none have been signed into law yet.
Even without a legal mandate, the employer landscape is pushing in the same direction. Hospitals increasingly treat the BSN as a minimum qualification for advancement, and completing one has become a practical necessity for nurses who want long-term career flexibility.
Pathways to Earning a BSN
The traditional route is entering a four-year BSN program straight out of high school. But several alternative pathways exist for people coming from different starting points.
- RN-to-BSN programs: Designed for registered nurses who already hold an ADN. These are typically online and take one to two years, since your prior nursing education and clinical experience count toward the degree.
- Accelerated BSN (ABSN) programs: Built for career changers who already hold a bachelor’s degree in a non-nursing field. Because general education requirements are already complete, ABSN programs focus almost entirely on nursing coursework and clinical preparation. They run 16 to 24 months depending on the school and require completion of prerequisite science courses before enrollment. Graduates earn the same BSN and are eligible to sit for the NCLEX-RN.
- Transfer students: If you already have a bachelor’s degree, you can also enroll in a traditional BSN program. General education credits often transfer, though science prerequisites may still need to be completed, and you would follow the same multi-year clinical sequence as first-degree students.
Regardless of the pathway, the end result is the same undergraduate credential. All BSN graduates hold a bachelor’s degree and qualify to take the NCLEX-RN to become licensed registered nurses.
What Comes After a BSN
Because the BSN is an undergraduate degree, it serves as the foundation for graduate-level nursing education. With a BSN, you can apply to a Master of Science in Nursing (MSN) program to become a nurse practitioner, nurse anesthetist, nurse midwife, or clinical nurse specialist. You can also pursue a Doctor of Nursing Practice (DNP) or a Ph.D. in Nursing. These advanced degrees open doors to independent practice, research, and executive healthcare leadership, but they all require the BSN as a starting point.
