Endocrinology and diabetes mellitus is a broad-ranging subject; and therefore an enticing one for trainees and consultants alike, since it encompasses basic mechanisms of physiology and pharmacology, coupled with the ability to improve quality of life and long-term outcomes through effective disease control and often cure.

Endocrinology and diabetes mellitus - trainee characteristics

Key skills in endocrinology & diabetes include:

  • an in-depth knowledge of the specialty

  • recognition of patients who require specialist input

  • willingness to work as both a member and leader of a team.

Working in an ST3 endocrinology and diabetes post

Endocrine and metabolic diseases are some of the most commonly-encountered in the UK population, and are increasing in prevalence and impact on the health of the nation - emphasising the need to continue to strive towards improved health care delivery in our specialty.

Widespread requirement for skills

Endocrine diseases and diabetes affect every physiological system of the body, determining that our specialists enjoy a wide range of skills and expertise, and make a major contribution to general medicine in its broadest sense.

Importance of endocrinology and diabetes

Historically, the specialty of endocrinology & diabetes has been at the forefront of both basic science and clinical research, determining that much of what we do has a strong evidence base.

Every trainee and specialist has the opportunity to contribute further to that growing evidence base, which has led to so many innovations in recent years.

    This specialty uses the standard ST3 eligibility criteria, and does not accept candidates from any alternative training routes.

    Please visit the am I eligible? section of this website for further information.

    Please note that due to the ongoing COVID-19 situation, certain recruitment processes have been affected for round 2 ST3 PSRO-coordinated specialties. As a result, the below information on this page is not applicable for this round only and should not be used where the process has changed. Please refer to the applicant guide for the latest information about how round 2 will operate.

    Further guidance about the scoring format of interviews will be published to each specialty page and we hope to have this updated by application closing date. Please visit the specialty pages closer to the time for updated information.


    Interview content

    You will spend approximately 10 minutes at each of the three interview stations, with three-to-five minutes' transfer time between each. Thus the overall time for the interview will be approximately 40-45 minutes.

    Click on the relevant stations below for more information on the content of the interview.

    Please note that this is subject to change, and will be confirmed by the date of interview.

    Establishing appointability

    Appointable - automatic

    If you are awarded a score of at least 3/5, for all marks given to you at your interview, then you will automatically be classed as appointable.

    Not appointable - automatic

    If any of the 12 scores awarded to you at interview are 1/5, this will reflect poor performance and an area of major concern.

    If three or more of your 12 interview scores are of 2/5, this will reflect several areas of concern across your whole interview.

    Should your interview assessment falls under either category above, the level of concern over your potential progression to ST3 will see your application classed automatically as not appointable .

    Appointability subject to panel decision

    In the event that your 12 interview scores contain one or two marks of 2/5 (and the rest 3/5 or above), your appointability status will be subject to discussion in the post-interview 'wash-up' meeting.

    The clinicians who have interviewed you will discuss your general performance during the interview and any concerns or otherwise they have about your application as a whole.

    Should they deem it appropriate, your application will be classed as appointable, and you can then be considered for post offers; whereas if they feel their concerns are too substantial for this outcome, they must class your application as not appointable, and it will progress no further in the current recruitment round.

    Review vs automatic status

    Please note there is no distinction made between candidates judged as appointable automatically, and those classed as appointable on review. Once deemed appointable it is only your overall score which will be used to determine ranking.

    Total score calculation

    After interview, a weighting is applied to the scores in each area, as well as the application form score, to give a 'total score'. This score determines your ranking which is used to inform how offers are made. The weighting of different sections, as well as the method by which your total score is established, can be seen by clicking on 'Total score calculation' below.

    Please note that this is subject to change, and will be confirmed by the date of interview.

    date of last review: 6 December 2019

    As part of the process of applying to ST3, you may wish to gain an idea of how recruitment progressed in previous years for the various specialties participating in the nationally-coordinated recruitment.

    To this end, we have published data dating back to 2013 (where this is available), based around four main areas:

    • Competition ratios - application numbers submitted to each specialty, along with the number of NTN and LAT posts available in each. It is worth noting that posts are subject to change throughout the round (increasing on average between 20-40%), and post numbers for this data are taken at the end of the round.

    • Shortlist scores - the scores awarded to all submitted applications, including average scores and distribution nationally.

    • Total scores - the total score awarded to all candidates who completed the full recruitment process for a specialty (application and interview), including some analysis of scores.

    • Post fill rates - the number of posts filled by region. 

    We have published information for all specialties participating in our process that year; consequently not all specialties will have data in all cases.

    Indicative post numbers

    Indicative vacancy numbers are available in the table below, broken down by region and divided between substantive national training number (NTN) and locum appointment for training (LAT) posts. In many cases these will be presented as a range (e.g. 1-4) as it is not always possible for regions to know at this stage how many vacancies there will be.

    It is the intention that indicative post numbers for all regions will be published prior to the application opening date, although this cannot be guaranteed. Please note that this table is not likely to be updated subsequent to indicative numbers and actual numbers will be confirmed when programme preferences are opened later in the round.

    Numbers subject to change

    Please be aware that it is not uncommon for vacancy numbers to change as the round progresses.

    More commonly, post vacancy numbers can increase as the round goes on (and confirmation of posts becomes available); but it is also possible that numbers can reduce as well. In the past, post numbers have risen an average of 20-40% from the start to the finish of the round but this can vary greatly for individual specialty/region combinations.

    It is possible that regions which do not have a post at the start of the round may declare one after applications have closed. Whilst we try and minimise instances of this, it is not always possible to predict vacancies so even if there appears not to be a vacancy in your preferred specialty/region combination, you may wish to consider applying in case one becomes available during the round; you can check with the region concerned if you wish to check on the likelihood of a post arising.

    Generally, once a region enter a post into a round they would always have at least one post available and would only withdraw it in exceptional circumstances.

    Please note that whilst we endeavour to keep the Physician ST3 recruitment website up to date, the SMT website will always be the more accurate one where they differ.

    Interview Content

    The interview will consist of three questions which range between 5 and 10 minutes in length. You will be marked on these three questions and your communication skills, giving four scored areas in total. You will be scored by two interviewers on each question.

    Including time for questioning and scenario reading, the interview will be approximately 35-40 minutes.

    Please note that this is subject to change and will be confirmed by the date of interview.

    Scoring Framework

    The score of 1-5 an interviewer will award you for each assessment area is judged in relation to how well you perform against an expected level. Below is the framework used to award scores at interview, as well as interpretation of what these scores represent:






















    not considered appointable


    area for concern

    performed below the level expected; possibly unappointable, subject to discussion and performance in other areas



    performed at the level expected during CT2; the candidate is suitable for an ST3 / LAT post



    above average ability; the candidate is suitable for an ST3 / LAT post



    highly performing trainee; the candidate is suitable for an ST3 / LAT post

    As shown in the table, for each of the question areas at interview, 3/5 is considered a satisfactory score; and reflects the level of performance that would be expected of a trainee ready to progress to a specialty training programme.

    Should your performance go above and beyond this expected level, interviewers can award marks of 4/5 or 5/5 as appropriate.

    Conversely, should your interview performance not reach the expected level, then interviewers can award marks of 1/5 or 2/5, as reflects their level of concern over your performance.


    From the eight scores awarded during your interview, an 'appointability' status will be calculated to determine whether you can be considered for an offer.

    The intention is to ensure successful candidates can display competence consistently across all areas of assessment covered at interview, rather than allowing outstanding achievement in one or more areas to make up for sub-par performance elsewhere.

    Appointability is awarded automatically and is based on two factors: individual interview scores and the 'raw interview score'.

    Appointability criteria

    To be classed as 'appointable', you must meet three criteria below:

    • none of your 8 interview scores can be 1/5
    • no more than two of your 8 interview scores can be 2/5
    • your RIS must be 24 or above.

    If you meet all three requirements, your application will be assessed as appointable, and can progress to be considered for post offers.

    However, if you fail to meet any of these requirements, your application must then be assessed as not appointable, and it will progress no further in that round.

    Total Score

    After interview, a weighting is applied to the scores in each area, as well as your application score.

    These scores are then combined to give your total score which determines your ranking, which will in turn be used to inform how offers are made. The weighting of different sections, as well as the method by which your total score is established, is detailed in the table accessible through the link below:
