If you already hold a bachelor’s degree in a non-nursing field, you can become a registered nurse in roughly 12 to 18 months through an accelerated nursing program, plus a few additional weeks for licensing. That’s significantly faster than the traditional four-year route, because your existing degree covers most of the general education requirements.
The Fastest Route: Accelerated BSN Programs
Accelerated Bachelor of Science in Nursing (ABSN) programs are designed specifically for people who already have a bachelor’s degree in another subject. These programs compress the full nursing curriculum into an intensive format that typically runs 12 to 18 months. Oregon Health & Science University, for example, completes its accelerated program in 15 months and covers all the same material as a traditional four-year track.
The pace is demanding. Most ABSN programs run year-round with no summer breaks, and course loads are heavy because you’re fitting two years of nursing education into roughly half the time. Clinical rotations happen alongside classroom learning, so expect full-time commitment with little room for outside work. The trade-off is clear: you’re a nurse more than two years sooner than someone starting from scratch.
Prerequisites You May Still Need
Having a bachelor’s degree doesn’t guarantee you’ve completed every prerequisite for nursing school. Most programs require a specific set of science and social science courses before you can enroll. At Rutgers School of Nursing, for instance, the prerequisite list for second-degree students includes:
- Anatomy and Physiology I and II (with labs)
- Microbiology (with lab)
- Organic Biochemistry or General Chemistry II
- Nutrition
- Statistics
- Developmental Psychology (covering the full lifespan)
- General Psychology
- Introduction to Sociology
If your original degree was in biology or a health-related field, you may already have several of these. If you majored in something like English or business, you could need two to three semesters of prerequisite coursework before your accelerated program even starts. Science prerequisites are especially important: most schools require all four science courses to be completed with grades before you can apply, and they often must have been taken within the past 10 years.
This prerequisite phase is the variable that changes the total timeline most. Someone with the right science background could apply immediately. Someone without it might add 6 to 12 months of coursework up front, bringing the realistic total closer to two years.
The Direct-Entry Master’s Option
Another path worth knowing about is the direct-entry Master of Science in Nursing. These programs accept students with non-nursing bachelor’s degrees and award a master’s degree in nursing rather than a second bachelor’s. Columbia University’s program, for example, runs 15 months in its standard format. A hybrid version stretches across seven semesters for students who need more flexibility.
The advantage here is that you skip the BSN entirely and graduate with a higher credential. You’re still eligible to sit for the RN licensing exam, and the master’s degree opens doors to leadership roles, education positions, or further specialization sooner in your career. The cost is typically higher than an ABSN, so it comes down to whether the advanced degree fits your long-term goals.
Getting Licensed After Graduation
Finishing your nursing program doesn’t make you an RN. You still need to pass the NCLEX-RN, the national licensing exam, and the processing time varies by state. California, one of the slower states, currently takes 10 to 12 weeks to process licensure-by-examination applications and another 2 to 3 weeks to process NCLEX results. Many states move faster, with some issuing licenses within days of passing the exam.
If you need to start working sooner, some states offer interim permits that let you practice under supervision while waiting for full licensure. In California, an interim permit can be issued within 24 to 48 hours after your exam application is approved. Not every state offers this, so check with your state’s board of nursing.
Realistically, plan for one to three months between graduation and having your RN license in hand.
How This Compares to Starting From Scratch
A traditional BSN program requires about 120 credit hours, split evenly between 60 hours of prerequisites and general education and 60 hours of nursing courses. That typically takes four years for someone entering college for the first time. Your existing degree already accounts for the general education half, which is why accelerated programs can cut the timeline so dramatically.
The salary picture also favors completing a BSN-level education rather than taking the shorter associate degree route. RNs with a BSN earn an average of $92,000 per year compared to $75,000 for those with an associate degree, according to Payscale data from mid-2023. That $17,000 annual difference adds up quickly over a career, and many hospitals now prefer or require a BSN for hiring.
Realistic Total Timeline
Here’s what the full picture looks like for someone with a non-nursing bachelor’s degree:
- If prerequisites are complete: 12 to 18 months of nursing school, plus 1 to 3 months for licensing. Total: roughly 13 to 21 months.
- If prerequisites are needed: 6 to 12 months of prerequisite courses, then 12 to 18 months of nursing school, plus licensing. Total: roughly 19 months to 2.5 years.
- Direct-entry master’s route: 15 months (plus prerequisites if needed), plus licensing time.
The single biggest thing you can do to shorten your timeline is check the prerequisite list for your target programs now. If you’re missing science courses, you can start taking them at a community college while you prepare your applications. Many students overlap prerequisites with the application cycle so they’re ready to start the nursing program as soon as they’re admitted.
