Nurse · Healthcare's largest profession: from Scutari's lamp to the ICU monitor, the person who is still at the bedside when everyone else has gone home.
Nursing's entry route is shorter than medicine's but built on the same principle: nobody practices unsupervised without accredited training, supervised clinical hours and a license. The standard path nearly everywhere is a three- or four-year nursing degree heavy with hospital placements, followed by a national licensing exam or registration, then a supervised first year on the wards.
The interesting differences are between countries. The US licenses both two-year associate and four-year bachelor's graduates through one exam, the NCLEX; the UK and Australia require a degree and register graduates without a separate exam; Germany trains most nurses through a paid apprenticeship; and the EU sets a legal floor of 4,600 training hours, half of them clinical. The gates are real at every stage — but unlike medicine, the door stays open to second careers and late entrants.
Biology and chemistry are the near-universal expectations; mathematics matters for drug calculations. Volunteering or care-assistant work is increasingly what separates successful applicants, since programs select for evidence of realistic motivation as much as grades.
The filterCompetitive admission to nursing programs — UCAS points and interviews in the UK, ATAR in Australia, GPA plus prerequisites in North America. Popular programs turn away most applicants.
A bachelor of nursing (4 years in the US and most of Asia, 3 in the UK and Australia) alternating classroom science with supervised hospital placements; Germany instead runs a three-year paid apprenticeship, reformed in 2020 into a single generalist qualification. The EU's floor is 4,600 hours of training, at least half in clinical practice.
The filterClinical placements themselves — practice hours must be signed off by qualified mentors, and students who cannot demonstrate safe practice at the bedside fail regardless of written marks.
The US and Canada require the NCLEX-RN, a computer-adaptive national exam run by the NCSBN; the UK's Nursing and Midwifery Council and Australia's AHPRA register graduates of accredited degrees directly; Japan holds a single national examination every February.
The filterThe exam or register itself — no pass, no practice. Internationally trained nurses face an additional gauntlet of credential checks, English tests and clinical OSCEs.
New nurses work under a preceptor through a structured first year — 'preceptorship' in the UK, nurse residency programs in many US hospitals — learning to carry a full patient load, run the medication round and survive the shift pattern.
The filterProbation and preceptorship sign-off. This is also the profession's leakiest point: a substantial share of new nurses leave their first job, or nursing entirely, within two years.
Experienced nurses branch into intensive care, emergency, operating theatre, oncology, pediatrics, mental health or community nursing, usually through employer-funded courses and national certifications such as the US CCRN for critical care.
The filterCertification exams plus required clinical hours — the CCRN, for instance, demands 1,750 hours of direct care of critically ill patients before a nurse may sit it.
The clinical peak is advanced practice — nurse practitioner, clinical nurse specialist, nurse anesthetist or nurse-midwife — via a master's or doctorate, with prescribing rights in a growing list of countries (the UK has allowed independent nurse prescribing since 2006). The management ladder runs charge nurse, ward manager, director of nursing.
The filterGraduate school admission plus national board certification — US nurse practitioners certify through ANCC or AANP exams, nurse anesthetists through the NBCRNA's National Certification Examination.
Germany pays its nursing apprentices roughly €1,100–1,340 a month during training, and Nordic countries charge no tuition at all. English students pay £9,250 a year but receive a non-repayable NHS grant of at least £5,000 annually. In the US the spread is huge: an associate degree at a community college can cost a few thousand dollars total, while a private-university BSN can exceed $120,000 — one reason the associate-to-bachelor's ladder survives.
The standard entry degree almost everywhere: nursing science, pharmacology, anatomy and ethics interleaved with well over a thousand hours of supervised hospital and community placement. In most countries only an accredited nursing degree leads to the register.
Graduates in life sciences are the main feedstock of accelerated nursing programs, which compress a nursing qualification into 12–24 months. The science overlaps heavily; what the accelerated year adds is clinical hours and judgment.
Psychiatric and mental-health nursing is one of the profession's largest specialties, and a psychology background maps directly onto it — several countries, including the UK, let students specialize in mental-health nursing from the first year of the degree.
School nursing, health visiting, vaccination programs and epidemiology-adjacent roles draw on public-health training; the public-health nurse tradition runs straight back to Lillian Wald's Henry Street Settlement in 1890s New York.
Paramedics, care assistants and allied-health workers carry directly relevant clinical experience, and many countries run bridge or credit arrangements into nursing degrees — England's nursing associate role, created in 2017, was designed explicitly as such a ladder.
Direct descendant of the 1860 Nightingale Training School at St Thomas' Hospital — the world's first secular nursing school — and a perennial top-three faculty in world nursing rankings.
Repeatedly ranked the world's best nursing school in the QS subject rankings; a research powerhouse whose faculty produced much of the evidence linking nurse staffing levels to patient mortality.

Canada's top-ranked nursing faculty, in the country that in 2015 adopted the US NCLEX-RN as its own licensing exam — making the two national systems unusually interchangeable.
One of the largest nursing faculties in the southern hemisphere and a fixture of the global top ten for nursing, supplying a health system where nursing has been all-graduate-entry since the 1990s.

The computer-adaptive national licensing exam run by the National Council of State Boards of Nursing; Canada adopted it in 2015. The case-study-based 'Next Generation' redesign launched in April 2023. Passing it, plus a state or provincial license, is the sole gateway to RN practice.
The Nursing and Midwifery Council's register — over 800,000 nurses and midwives — is the legal requirement to practice. UK graduates of accredited degrees register directly; internationally trained nurses must pass a computer-based test plus a practical OSCE examination.
The Nursing and Midwifery Board of Australia registers graduates of accredited Australian degrees through the national regulator AHPRA. Internationally qualified nurses complete a staged pathway of credential assessment and, since 2023, a dedicated OSCE rather than costly bridging courses.
Japan licenses nurses through a single national examination held each February under the Ministry of Health, Labour and Welfare. Around 60,000 candidates sit it annually, and the pass rate for new graduates runs near 90 percent — the gate is getting through nursing school, not the final exam.
Training as a licensed practical/vocational nurse (about a year in North America) or as one of England's nursing associates (a two-year role created in 2017), then bridging to full registration through LPN-to-RN or top-up programs — earning wages and clinical experience the whole way. A large share of the RN workforce arrived by this ladder.
Graduates in any field can qualify through intensive 12–24 month accelerated bachelor's or master's programs, a route that grew rapidly in the US and UK as career changers entered after 2008 and again after COVID-19. Military nursing services in several countries sponsor the same training in exchange for service.
