Thesis or dissertation? The terms, explained
In Indian MD, MS and DNB training, “thesis” and “dissertation” name the same requirement: the NMC’s PGMER-2023 says “thesis” in its training rules and “dissertation/thesis” in its marking scheme, and NBEMS’s guidelines use both words. The synopsis, which NBEMS calls the thesis protocol, is the plan you submit before the study starts; the thesis is the finished report of that study.
Is a thesis the same as a dissertation?
In Indian postgraduate medicine, yes. The national documents use the two words for one requirement.
- The NMC’s PGMER-2023 says students “will do thesis related research and will write thesis” (clause 5.2(iii)), and its marking scheme gives 20 marks to the “dissertation/thesis”.
- NBEMS’s guidelines say the aim of “requiring the trainees to write a thesis/dissertation is to familiarize him/her with research methodology”.
Your university’s regulations may use either word; the requirement is the same, a study you carry out under your guide and report in full. Outside Indian medical training the two words are used differently from country to country, which is why general searches for “thesis vs dissertation” give conflicting answers.

What is the difference between a synopsis and a thesis?
The synopsis is the plan; the thesis is the finished study. The synopsis sets out the question, the objectives and the methods so that your guide, your department and the ethics committee can approve the study before it starts. The thesis reports what you did and found, chapter by chapter, once the data are in.
PGMER-2023 does not mention a synopsis at all, so for MD/MS its name, format and deadline come from your university. NBEMS calls the plan the thesis protocol, and uses “synopsis” in two narrower senses: a structured synopsis of 250 to 300 words inside the protocol, and a synopsis of the thesis sent with the finished thesis.

What is a thesis protocol?
NBEMS defines it like this:
“The protocol for a research proposal (including thesis) is a study plan, designed to describe the background, research question, aim and objectives, and detailed methodology of the study. In other words, the protocol is the ‘operating manual’ to refer to while conducting a particular study.”
Source: NBEMS thesis guidelines (2022), section II.
For DNB, each part of the protocol has a word limit, and the protocol is submitted online within 180 days of joining (90 days on the 2-year post-diploma course). Every limit is listed in DNB thesis guidelines.
Synopsis, protocol, thesis and paper: how do they compare?
| Document | What it is | When | Who approves or assesses it |
|---|---|---|---|
| Synopsis (MD/MS) | The plan of your thesis study | Before data collection, by your university’s date | Your guide and the ethics committee, then your university as its regulations require |
| Thesis protocol (DNB) | The same plan, to NBEMS’s word limits | Online within 180 days of joining (90 on the 2-year course) | Your hospital’s IEC; then it is submitted to NBEMS |
| Thesis or dissertation | The full report of the study | MD/MS: your university’s date. DNB: 26 months from joining (15 on the 2-year course) | MD/MS: an external examiner at the final exam, with a viva. DNB: assessed through NBEMS, which must accept it |
| Research paper | A journal article | Any time in training | The journal’s peer review. Under PGMER-2023, one first-author paper published or accepted is one route to final-exam eligibility |

What is ethics committee (IEC) approval?
Before a study on human participants, their biological material or their data begins, an appropriately constituted ethics committee must review and approve it, and it keeps monitoring the study while it runs. That is ICMR’s national rule. NBEMS makes IEC approval mandatory before any DNB thesis research starts, and a DNB hospital’s IEC must be registered with the National Ethics Committee Registry for Biomedical and Health Research (NECRBHR).

What is CTRI registration, and does a thesis need it?
The Clinical Trials Registry–India (CTRI), launched by ICMR on 20 July 2007, is a free online public record of clinical trials, PG theses and other biomedical research in India. Registration has been mandatory since 15 June 2009 for clinical trials under the Drugs and Cosmetics Act and its Rules; for other biomedical and health research, ICMR’s 2017 guidelines describe it as voluntary. Editors of major Indian journals have said they will consider only registered trials for publication, which matters if you plan to publish a trial from your thesis.

What are the research methodology course and BCBR?
PGMER-2023 requires every MD/MS student to complete an online course in research methodology, taken by registering on the portal of the designated training institution and expected in the first year; the certificate is needed to sit the final exam. For DNB and DrNB trainees admitted from the 2025 session, NBEMS requires the Basic Course in Biomedical Research (BCBR), an online course in research methodology and biomedical ethics from ICMR’s National Institute of Epidemiology, before the thesis is submitted.
