A junior doctor is a qualified medical professional who has completed a full medical degree and is working through postgraduate clinical training. Despite the word “junior,” these doctors can have up to nine years of hospital experience depending on their specialty. The term is primarily used in the United Kingdom, where roughly 75,000 doctors in training roles work across the NHS in England alone. In 2024, the British Medical Association began formally replacing “junior doctor” with “resident doctor” to better reflect the expertise these physicians bring to patient care.
Why the Term Can Be Misleading
The phrase “junior doctor” covers an enormous range of experience. It applies equally to a doctor on their very first day after medical school and to a specialist trainee with seven or eight years of hands-on clinical work. A senior surgical trainee performing complex operations independently still technically holds the “junior doctor” title until they complete training and are appointed as a consultant.
This confusion is one reason the BMA pushed for the shift to “resident doctor.” In the United States and many countries that follow the American model, a doctor who has graduated medical school and is still training is called a resident, a title considered more respectful of the skills and knowledge acquired through years of study and practice. The UK’s adoption of “resident doctor” aligns the terminology more closely with international norms.
The Training Pathway
All medical graduates in the UK must complete an integrated two-year foundation programme before they can practise independently. Foundation Year 1 (FY1) and Foundation Year 2 (FY2) act as a bridge between medical school and specialty training, rotating doctors through different hospital departments to build broad clinical skills.
After the foundation programme, doctors choose a specialty track. General practice training takes approximately three years, while hospital specialties range from five to seven years through what’s called run-through training. Some paths split into core training (two to three years of broad experience in a specialty area) followed by a competitive application into higher specialty training. Emergency medicine trainees, for example, typically enter through a three-year Acute Care Common Stem programme before progressing further.
Each stage has specific competencies that must be met before a doctor can advance. A clinical supervisor in each department oversees day-to-day work during a given rotation, while a separate educational supervisor stays with the trainee across the entire programme to track their overall development. Only after completing all required training years and passing final assessments does a doctor become a consultant (in hospital medicine) or a fully qualified GP.
What Resident Doctors Actually Do
The dominant role of a resident doctor is supporting the ward team and senior doctors. On a typical day, this means admitting new patients, processing tasks that arise from consultant-led ward rounds, coordinating with other specialists, arranging discharges, and communicating with primary care teams about patients going home. Communication tasks make up the single largest category of daily work, accounting for more of a resident doctor’s time than any other activity type.
Resident doctors also perform hands-on clinical procedures. Common ones include inserting IV lines, placing nasogastric tubes, urethral catheterisation, and taking arterial blood gas samples. These are often tasks that fall to them after nursing staff have made unsuccessful attempts. Foundation doctors are generally expected to perform arterial blood gas sampling unsupervised from their very first day of practice.
Out-of-hours shifts look quite different from daytime work. Evenings, nights, and weekends involve more direct patient care, both on the wards and in emergency admission units, with less senior backup physically present. Resident doctors working overnight may be the first responder for deteriorating patients across multiple wards, making clinical decisions and escalating to consultants by phone when needed. They also participate in sensitive conversations with families, including discussions about resuscitation decisions.
Pay Scales in England
Resident doctor salaries in England rise with each training stage. As of the most recent pay scales, a Foundation Year 1 doctor earns a base salary of £38,831. This increases to £44,439 in Foundation Year 2. Core or specialty trainees in their first two years earn £52,656, rising to £65,048 at the CT3 or ST3 level. The most senior resident doctors, at the ST6 through ST8 grades, earn a base of £73,992.
These figures represent basic pay before additional supplements for working unsocial hours, nights, and weekends. Because resident doctors regularly work evenings and overnight shifts, their actual take-home pay is typically higher than the base figure. Still, when spread across the actual hours worked, the effective hourly rate has been a central point of contention in recent pay disputes.
Working Hours and Protections
Resident doctors’ contracts include specific safeguards against excessive hours. Shifts cannot be rostered beyond 13 hours. There must normally be at least 11 hours of continuous rest between shifts, and if that rest is broken, compensatory time off must be given within 24 hours.
Additional rules govern intensive stretches of work:
- Long shifts: No more than four consecutive days of shifts exceeding 10 hours, followed by a minimum 48 hours of rest.
- Night shifts: No more than four consecutive shifts where at least three hours fall between 11 p.m. and 6 a.m., followed by a minimum 46 hours of rest.
- Breaks: A paid 30-minute break for any shift over five hours, a second for shifts over nine hours, and a third for night shifts exceeding 12 hours.
These protections exist on paper, but enforcement depends on accurate reporting. Hospitals track compliance through work schedule reviews, and breaches can trigger financial penalties paid directly to the affected doctor.
How the UK System Compares Internationally
The concept of a doctor-in-training exists everywhere, but the structure and terminology vary. In the United States, medical school graduates enter residency programmes lasting three to seven years depending on specialty, followed by optional fellowship training for subspecialisation. The American “resident” is the closest equivalent to a UK resident doctor, though the training structures differ in their entry points and assessment methods.
One key distinction is that UK medical students enter medical school directly after secondary school, typically completing a five- or six-year undergraduate degree. American medical students complete a four-year undergraduate degree first, then four years of medical school. This means a UK foundation doctor may be as young as 23 or 24, while a US first-year resident is usually at least 26. Despite the age difference at entry, both are fully qualified doctors with the legal authority to prescribe medications and make clinical decisions under supervision.
