UPSC CMS is the Combined Medical Services Examination held by the Union Public Service Commission (UPSC). It recruits MBBS doctors as medical officers in central government services, such as the Central Health Service and the Indian Railways.
The exam has two stages - a computer-based written exam with two papers, and a personality test. It is one of the few routes for a fresh MBBS graduate to get a permanent central government post without a post-graduate degree.
- UPSC CMS recruits MBBS doctors for central government medical posts.
- The written exam has two papers of 250 marks each, with negative marking.
- A personality test of 100 marks follows for shortlisted candidates.
- Posts, vacancies and age rules are given in each notice - confirm them in the current UPSC notification.
Posts filled through CMS
Recent CMS notices have included posts such as:
- Junior Scale posts in the General Duty Medical Officer sub-cadre of the Central Health Service.
- Assistant Divisional Medical Officer in the Railways.

The list of posts and vacancies changes each year. Candidates give an order of preference for posts, and allotment is made by rank and preference.

Exam pattern
| Stage | Details | Marks |
|---|---|---|
| Paper I | 120 objective questions, 2 hours | 250 |
| Paper II | 120 objective questions, 2 hours | 250 |
| Personality Test | For candidates shortlisted after the written exam | 100 |
The total is 600 marks. The written exam is computer-based, and one-third of the marks for a question are cut for each wrong answer.
Paper I and Paper II syllabus
| Paper | Subjects | Questions |
|---|---|---|
| Paper I | General Medicine (including cardiology, neurology, dermatology and psychiatry) | 96 |
| Paediatrics | 24 | |
| Paper II | Surgery (including ENT, ophthalmology, traumatology and orthopaedics) | 40 |
| Gynaecology and Obstetrics | 40 | |
| Preventive and Social Medicine | 40 |
General Medicine alone carries the largest share, so it needs the most time. Preventive and Social Medicine (community medicine) is also high-scoring, since many questions come from national health programmes and basic statistics.
Personality test
The personality test checks whether the candidate is suitable for a public medical service. The board may ask about:
- Your medical knowledge and clinical reasoning.
- Your internship experience and cases you handled.
- Public health issues and national health programmes.
- Your communication, ethics and attitude towards patients.
Final merit is based on the written exam and the personality test together.
Pay and service conditions
Junior Scale medical officer posts filled through CMS have been placed at Level 10 of the 7th Pay Commission pay matrix, with a starting basic pay of ₹56,100. Doctors in many of these posts also get a non-practising allowance, as private practice is not allowed, along with dearness allowance and other central allowances as per rules.
Officers move up through time-bound promotions to Senior Medical Officer, Chief Medical Officer and higher grades. Many also study for a post-graduate degree later while in service, under the rules of their department.
Life as a medical officer
- In the Central Health Service, doctors work in central government hospitals and CGHS dispensaries in many cities.
- In the Railways, doctors run railway hospitals and health units, and also handle medical fitness checks of staff and first response to accidents.
- In Delhi municipal bodies, doctors work in civic hospitals and dispensaries.
The work mixes clinical care with administration and public health duties, so leadership and communication matter as much as medical skill.
Important topics to revise
- General Medicine - infectious diseases, cardiology, endocrinology (diabetes, thyroid), respiratory diseases, neurology and emergencies.
- Paediatrics - growth and development, immunisation, neonatal care, nutrition and common childhood infections.
- Surgery - trauma, burns, abdominal surgery, breast and thyroid, urology and orthopaedic basics.
- Gynaecology and Obstetrics - antenatal care, labour, high-risk pregnancy, contraception and common gynaecological conditions.
- Preventive and Social Medicine - national health programmes, epidemiology, biostatistics, nutrition and environmental health.
CMS vs NEET PG
| Point | UPSC CMS | NEET PG |
|---|---|---|
| Purpose | A government job as medical officer | Admission to MD/MS/diploma seats |
| Held by | UPSC | National Board of Examinations |
| Stages | Two papers and personality test | One computer-based exam |
| Syllabus overlap | Clinical subjects and community medicine | All MBBS subjects, including pre- and para-clinical |
Many doctors prepare for both together, since the clinical part overlaps a lot.
How to apply
- Complete the one-time registration on the UPSC online portal, if not done already.
- Fill the CMS application, with educational details and post preferences.
- Pay the fee (exempt for some categories) and choose an exam centre.
- Download the e-admit card before the exam and read all instructions.
UPSC usually releases the CMS notice in the first half of the year. Watch the UPSC exam calendar for the date.
A simple study plan
| Phase | Focus |
|---|---|
| Weeks 1-6 | General Medicine and Paediatrics from standard textbooks and short notes |
| Weeks 7-10 | Surgery and Gynaecology and Obstetrics |
| Weeks 11-12 | Preventive and Social Medicine, national programmes and biostatistics |
| Weeks 13-16 | Previous CMS papers, full mocks and revision of weak areas |
How to prepare
Start with previous papers. CMS repeats many topics. Solving ten years of papers shows what to focus on.
Clinical focus. Questions are often based on a short case. Practise reading the case, finding the key sign and choosing the next step.
Community medicine. Learn the national health programmes, vaccination schedule, epidemiology terms and simple statistics. These questions are direct and score well.
Accuracy. With one-third negative marking, avoid guessing between four close options. Mark only when you can rule out at least two.
Exam-day plan. Finish easy questions in the first pass, mark doubtful ones, and keep fifteen minutes to review.
Documents to keep ready
- Class 10 certificate for date of birth.
- Marksheets and certificates of the MBBS degree, internship completion certificate and medical council registration.
- Caste, EWS, non-creamy layer or disability certificate in the format given in the notice, where relevant.
- Photo identity proof, recent photographs and a signature scan for the online form.
Make sure your name and date of birth match across all documents. Mismatches cause trouble at verification.
Common mistakes
- Ignoring Preventive and Social Medicine. It is one-third of Paper II.
- Too much guessing with negative marking.
- Not filling post preferences carefully.
- Missing the internship completion deadline before appointment.
- Using an old syllabus. Follow the latest UPSC notice.
