Educational Qualification: MBBS Degree & Appearing Rules
Understanding the academic standards set by the National Medical Commission (NMC) and the provisions for final year MBBS aspirants.
Mandatory MBBS Degree
Candidates must have passed the written and practical parts of the final MBBS examination from a recognized Indian medical institute or university included in the Schedule of the NMC Act, 2019.
Final Year Appearing Provision
A candidate who has appeared or has yet to appear at the final MBBS examination may also apply provisionally. Such candidates will be admitted to the Written CBT examination.
Foreign Medical Graduates (FMG)
Foreign medical graduates who hold primary medical qualifications from abroad are eligible provided they have cleared the FMGE (Screening Test) conducted by NBE and possess valid NMC registration.
No Minimum Percentage Cap
UPSC does not mandate any minimum aggregate percentage in MBBS (such as 50% or 60%). Passing the qualifying MBBS examination is sufficient to apply.
Compulsory Rotatory Internship (CRRI) Guidelines
Can you take the UPSC CMS examination while undergoing your 1-year internship duties?
One of the most frequent dilemmas among medical aspirants is whether internship completion is mandatory before filling out the online application. Here is the official UPSC stance:
Applying for Written Exam (Computer Based Test)
Doctors who are currently completing their Compulsory Rotatory Residential Internship (CRRI) are 100% eligible to submit their application and sit for Paper 1 and Paper 2.
Personality Test / Interview Stage
Candidates called for the Personality Test must submit proof of passing the final MBBS examination and their provisional registration certificate during DAF submission.
Final Cadre Allocation & Appointment
Candidates who qualify both Written and Personality tests will be appointed to the respective service (Railways, CHS, NDMC, MCD) only after completion of the compulsory rotating internship and grant of permanent registration by NMC or State Medical Council.
Nationality & Citizenship Criteria
Eligibility requirements for Indian citizens and international applicants.
To be eligible for the UPSC Combined Medical Services Examination, a candidate must be either:
- A Citizen of India, or
- A Subject of Nepal, or
- A Subject of Bhutan, or
- A Tibetan refugee who came over to India before the 1st January, 1962 with the intention of permanently settling in India, or

Number of Attempts in UPSC CMS
How many times can a doctor appear for the Combined Medical Services exam?
There is no cap on the number of attempts for UPSC CMS. A doctor can take the examination every consecutive year until reaching the maximum upper age limit for their category.
Unlike CSE which strictly limits General candidates to 6 attempts and OBC to 9 attempts, CMS permits limitless attempts to ensure maximum qualified doctors can join public health services.
