Getting Ethics Committee Approval for Postgraduate Research

Why you need ethics approval before you start

Any research involving people, their data, or animals needs formal ethics clearance before you recruit a single participant. This applies to interviews, surveys, clinical samples, classroom observation, and even secondary analysis of identifiable records. Universities across Africa run this through a research ethics committee (REC) or institutional review board (IRB), and collecting data before approval can get your results thrown out at examination.

Committees exist to protect participants from harm, protect you from legal and academic liability, and confirm your study meets scientific standards. Skipping this step is one of the most common reasons a thesis defense gets delayed.

Who reviews your protocol

Your first stop is your university's REC or IRB, usually attached to the postgraduate school or a specific faculty such as medicine, health sciences, or education. The University of Ibadan's UI/UCH Research Ethics Committee is one of the oldest in Nigeria and reviews all research involving human subjects at the university and its teaching hospital, checking protocols against global standards as well as national ones.

At the University of Nairobi, health-related research goes through the joint KNH-UoN Ethics and Research Committee , run with Kenyatta National Hospital. The committee publishes guidelines for proposal development and an application checklist you should follow before submission.

In South Africa, individual university RECs must register with the National Health Research Ethics Council (NHREC) , a statutory body under the National Health Act. NHREC-registered committees follow the Department of Health's Ethics in Health Research Guidelines, so your protocol at Stellenbosch, Pretoria, or Wits follows the same national baseline even though each university runs its own committee day to day.

If your study is not health-related, for example a social sciences or education thesis, your faculty's own REC handles the review, often with a lighter process than a medical committee.

What to submit

• A full research protocol: background, objectives, methodology, and sample size

• Participant information sheet written in plain language

• Informed consent form, including how participants can withdraw

• Data management plan: how you store, anonymize, and eventually destroy data

• Recruitment materials, such as adverts or invitation letters

• Any data collection instruments: questionnaires, interview guides, or test forms

• Supervisor's signature and departmental approval, where required

Committees want to see that participants understand what they are agreeing to and that you have a real plan for keeping their data safe, not just a summary of your research question.

Common revision requests

Reviewers rarely approve a protocol on the first pass. Expect feedback on:

• Consent forms that use technical language instead of plain terms

• No clear explanation of how you will protect anonymity in small or identifiable samples

• Missing detail on where data will be stored and for how long

• Recruitment methods that could pressure participants, such as recruiting your own students

• No plan for what happens if a participant becomes distressed during an interview

Address every point the committee raises directly in your resubmission letter. Committees move faster through a protocol that responds point by point than one that just resubmits a rewritten document.

How long approval takes

Timelines vary by university and by how busy the committee is, but plan for several weeks to a few months from first submission to final approval, especially if your study involves minors, patients, or sensitive topics. Committees typically meet on a fixed cycle rather than reviewing on demand, so a protocol submitted just after a meeting can sit for weeks before the next one. Build this into your research timeline from the start rather than after your supervisor approves your proposal.

Tips to move faster

• Download your committee's checklist and application form before writing your protocol, not after

• Ask your supervisor or department for a sample of a previously approved protocol in your field

• Submit before the deadline for the next scheduled meeting, not the day it falls

• Keep consent forms short and written for a general reader, not an academic one

• Respond to revision requests within the window the committee gives you, since some committees close files after a set period of inactivity
