Becoming a registered nurse is genuinely difficult, but not in one single way. The challenge shifts at each stage: getting accepted into a competitive program, surviving a demanding curriculum heavy on science and clinical hours, and passing a licensing exam designed to test real-world judgment. In 2024 alone, over 80,000 qualified applications were turned away from nursing schools nationwide. The path is doable, but it requires more preparation and persistence than many people expect going in.
Getting Into Nursing School
The first real obstacle is admission. Nursing programs at every level are capacity-limited, largely because there aren’t enough faculty to teach more students. The American Association of Colleges of Nursing reported that in 2024, 65,398 qualified applications to entry-level bachelor’s programs were not accepted. That number represents applications rather than individual people (since one person may apply to several schools), but it still signals how tight seats are.
Most programs require a cumulative GPA of at least 3.0 in prerequisite courses, though competitive applicants often need higher. At community colleges offering associate degree programs, waitlists are common even for students who meet every requirement. The bottleneck isn’t a lack of interested students. It’s a lack of open spots.
Prerequisites Before You Even Start
Before you set foot in an actual nursing class, you’ll spend one to two years completing prerequisite science courses. A typical list looks something like this:
- Human Anatomy (with lab)
- Human Physiology
- General Biology
- Elementary Chemistry (with lab)
- Medical Microbiology
- Pathophysiology
- Statistics
- Nutrition
- Human Growth and Development
That’s nine courses before the nursing curriculum begins, and many programs require a minimum 3.0 GPA across them. Some schools also put time limits on certain classes. The University of Utah, for example, requires that anatomy and physiology be taken within seven years of your application deadline, meaning older coursework may need to be repeated. For career changers or people returning to school after a gap, this alone can add a year to the timeline.
What Nursing School Itself Is Like
Once admitted, the pace picks up sharply. Nursing programs compress a large volume of clinical knowledge into a short window. You’ll study pharmacology, patient assessment, medical-surgical nursing, maternal health, pediatrics, mental health, and more, often while simultaneously completing clinical rotations at hospitals and community health sites.
The workload takes a measurable toll. A study of 266 undergraduate nursing students found that 62% reported high levels of emotional exhaustion and nearly 62% met the threshold for high academic burnout overall. About 65% scored high on disengagement, a state where students feel mentally checked out from their studies despite continuing to show up. These numbers reflect a program structure that demands constant attention: exams come frequently, clinical days can run 10 to 12 hours, and the material builds on itself with little room to fall behind.
Roughly 20% of nursing students in the United States don’t finish their program. Attrition rates globally range from 10% to over 30% depending on the country, but in the U.S. the commonly cited figure is around one in five. Students leave for a mix of reasons: academic failure, financial strain, personal circumstances, or burnout. The programs that retain students well tend to offer strong mentorship and early intervention when grades slip.
Clinical Hours Add a Physical Dimension
Nursing isn’t just classroom learning. Every state board of nursing requires hands-on clinical experience before you can graduate and sit for the licensing exam. The specific hour requirements vary widely. At least 13 state boards set a minimum number, ranging from 250 to over 1,000 hours. California, for instance, requires at least 500 hours of direct patient care in approved clinical settings, with a minimum of 30 hours dedicated to each nursing specialty area.
Clinical rotations are where the difficulty becomes physical, not just intellectual. You’re on your feet for long shifts, learning to start IVs, assess patients, document care in real time, and communicate with physicians and families. Mistakes in this setting carry real consequences, which creates a level of pressure that textbook studying alone can’t replicate. Many students describe clinicals as the hardest and most rewarding part of the program simultaneously.
The NCLEX Licensing Exam
Graduating from nursing school doesn’t make you a registered nurse. You still need to pass the NCLEX-RN, a computerized adaptive exam that adjusts its difficulty based on your answers. The current format places heavy emphasis on clinical judgment: recognizing warning signs in patient data, prioritizing care across multiple patients, and making decisions under uncertainty.
The exam uses unfolding case studies that follow up to four patients at once, mirroring real nursing practice where you’re never managing just one person in isolation. You’ll be asked to recognize cues, analyze information, and prioritize interventions across scenarios that evolve as you answer. The test can end in as few as 75 questions or extend to 145, depending on how consistently you demonstrate competence above the passing standard.
First-time pass rates for U.S.-educated candidates have historically hovered in the mid-to-high 80% range, meaning most graduates do pass on their first attempt. But the exam requires dedicated preparation, typically four to eight weeks of focused review after graduation. Students who underestimate it or delay studying often struggle.
Time and Cost From Start to Finish
The two main pathways to becoming an RN differ significantly in time and expense. An Associate Degree in Nursing (ADN) is a two-year program, typically offered at community colleges, with tuition ranging from $6,000 to $20,000. Some accelerated ADN programs finish in 18 months. A Bachelor of Science in Nursing (BSN) is a four-year program at a college or university, with total costs ranging from $40,000 to over $200,000 depending on whether the school is public or private.
Both paths lead to the same licensing exam and the same RN credential. However, the trend in healthcare hiring increasingly favors BSN-prepared nurses, and many hospitals now require or strongly prefer a bachelor’s degree. If you start with an ADN, you can work as an RN while completing an RN-to-BSN bridge program later, though that adds another one to two years of part-time study.
Factor in the prerequisite courses, and the realistic timeline from “deciding to become a nurse” to “working as an RN” is three to five years for most people. That assumes you get into a program without a long wait, don’t need to repeat any courses, and pass the NCLEX on your first try.
Where the Difficulty Really Lives
The honest answer is that becoming an RN is hard in a cumulative way rather than any single dramatic hurdle. The prerequisites are manageable individually but demanding as a set. Getting accepted requires patience and a strong academic record. The program itself is intense, both mentally and physically. And the licensing exam requires you to think like a practicing nurse, not just recall facts.
What makes it achievable is that each step is well defined. You know exactly which courses to take, what GPA to aim for, how many clinical hours you need, and what the exam covers. There are no hidden requirements. The difficulty comes from sustaining effort across years, not from any single impossible barrier. Students who plan ahead, stay consistent with studying, and build a support network around themselves tend to make it through, even when burnout hits hard in year two or three.
