Adrenaline junkies rejoice!
Doff your bike helmet, slam the remains of your coffee, and have a gander at the options that Acute Care Common Stem (ACCS) Training can bring to those who like their medicine with a side helping of adrenaline.
If you like a bit of variety in your work, ACCS brings you rotations across Emergency Medicine, Acute Medicine, Anaesthetics, and Intensive Care Medicine (ICM) – giving you some flexibility in your future career.
Confused about how it all works? You’re not alone.
In this guide, we’ll go through the training pathways available, whether you should apply, and the curriculum. For scale: NHS England's 2025 competition ratios were 14.23 for ACCS Emergency Medicine, 12.56 for Anaesthetics CT1 and 5.27 for IMT/ACCS-IM (2026 figures are not yet published).
The ACCS Training Pathway
Acute Care Common Stem (ACCS) training is a broad-based training programme for post-FY2 doctors that gives trainees experience in Emergency Medicine, Acute Medicine, Anaesthetics, and Intensive Care Medicine. The aim is to give trainees a broader understanding of all things acute while offering more flexibility to change career direction down the line.
Training is made up of three separate programmes – ACCS EM (Emergency Medicine), ACCS Anaes (Anaesthetics), and ACCS IM (Internal Medicine – previously known as ACCS AM for Acute Internal Medicine). All three programmes share the same curriculum and rotations for the first 2 years, then diverge for the final 1-2 years to fulfil the training requirements of their respective specialities.
The first two years of training are the same across all three programmes:
- Emergency Medicine - 6 months
- Acute Medicine - 6 months
- Anaesthetics - 6 months
- Intensive Care Medicine - 6 months
The programmes then diverge into training for their respective specialities for a further 1-2 years.

For emergency medicine trainees, ACCS-EM is the only entry route, and it is now recruited as run-through training from ST1 - NHS England states "There will no longer be a Core Training option". After the two-year common stem and a third year in emergency medicine, run-through trainees continue straight into higher emergency medicine training rather than applying again at ST4.
For both ACCS-IM and ACCS-Anaes, however, the programme is a 4-year alternative to their 3-year core training programmes – Internal Medicine Training and Core Anaesthetics Training. This means that following 2 years of broad-based training, you must undertake an additional 2 years to meet the requirements to apply for higher speciality training (ST4).
Should you have a change of heart during training, it’s much easier to switch to another ACCS speciality than if you had chosen a traditional core training programme. This pathway also opens up more options for obtaining an additional CCT (certificate of completion of training) in Intensive Care Medicine (ICM).
Acute Care Common Stem - Emergency Medicine (ACCS EM)
This is the 3-year ACCS phase of the run-through Emergency Medicine programme (ST1 to ST6) - the only entry route into emergency medicine training. Following two years of broad-based training (which includes 6 months of emergency medicine), the third year is spent in emergency medicine
Trainees use the Royal College of Emergency Medicine's e-portfolio to document their curriculum progress and work-based assessments, but in the first two years of training share the same core learning outcomes as their ACCS counterparts.
Before continuing in higher speciality training, trainees must complete three life support courses – ALS, ATLS, and APLS (or equivalent) – undertake level 3 safeguarding children training and pass the three MRCEM exams (MRCEM Primary, MRCEM SBA and MRCEM OSCE, in that order).
Selection for 2027 entry: ACCS-EM ST1 uses the MSRA and an online interview - "The MSRA will be weighted 40% and the interview score 60% of the total score." The interview is two 10-minute stations via Qpercom Recruit, one a portfolio station and the other a clinical/ethical station, and emergency medicine does not take part in Round 3.
Acute Care Common Stem – Internal Medicine (ACCS IM)
Previously known as ACCS-AM, this is a 4-year programme and is an alternative to the Internal Medicine Training (IMT) programme. After 2 years of broad-based training, ACCS IM trainees follow the IMT programme at the IMY2 level, with the same requirements for completion of the programme.
While ACCS-IM trainees will have to train for an extra year, the extra time gives them a better understanding of emergency care and a better opportunity to boost their ST4 application points. Choosing this path to higher speciality training means spending an extra year to gain competencies in emergency medicine, intensive care, and anaesthetics.
ACCS Internal Medicine shares the same recruitment and application process as IMT, using the same self-assessment score, with both undergoing the same IMT interview. For 2027, shortlisting is based entirely on the self-assessment score (the five extra points given in 2026 to applicants who applied only to the joint IMT/ACCS-IM vacancy have been removed), and there are two vacancies: one for England, Northern Ireland and Wales, and a separate one for all programmes in Scotland.
ACCS IM vs IMT
While the sister programme, Internal Medicine Training (IMT), is a 3-year training programme, the ACCS-IM programme contains additional training in emergency medicine and anaesthetics and therefore requires an additional year to complete. ACCS-IM trainees take part in the equivalent of IMY2 & IMY3 in their CT3 and CT4 years.
If you choose this programme, you will spend approximately 6 months less time in medical specialities when compared to IMT. During the final 2 years of ACCS-IM, trainees are expected to pass the three MRCP exams. After completion, trainees can apply for ST4 posts in higher medical specialities. Note the IMT recruitment guidance: "Successful completion of the third year of ACCS-IM will enable entry to Group 2 physician specialties only."
The ACCS-IM programme also shortens higher speciality training in Intensive Care Medicine if you choose to pursue an Acute Medicine/Intensive Care Medicine dual CCT.
Acute Care Common Stem - Anaesthetics (ACCS Anaes)
This is a 4-year programme and is an alternative to the Core Anaesthetics Training programme. Following the first 2 years, ACCS Anaesthetics trainees will undergo a further 2 years of training in anaesthetics to meet requirements for higher speciality training.
Taking the ACCS Anaesthetics path means spending an extra year in training compared to core anaesthetics training, to receive training in emergency medicine, acute medicine, and intensive care medicine. While this involves an extra year, it is an excellent option for anaesthetics trainees who wish to pursue a career in intensive care medicine.
ACCS Anaesthetics is recruited via the same pathway as Core Anaesthetics, with both undergoing the same CT1 anaesthetics interview.
During the final 2 years of ACCS Anaesthetics, trainees are expected to pass the three FRCA primary exams. Following completion, trainees can apply for ST4 anaesthetics.
ACCS Anaes vs Core Anaesthetics
Core Anaesthetics Training is a 3-year training programme, whereas trainees in Acute Care Common Stem Anaesthetics undertake an additional 6 months in both acute medicine and emergency medicine, meaning it is a 4-year programme.
If you choose the ACCS Anaes training programme you will share the same 2 first years of training as your emergency and internal medicine counterparts. You will then diverge and join the Core Anaesthetics curriculum at a CT2 equivalent level for your CT3 and CT4 years. You will spend the same amount of time in anaesthetics and intensive care as core anaesthetics trainees.
