A research proposal aims to present your idea or your question and expected outcomes with clarity and definition – the what.
It also seeks to make a case for the reason your question is significant, the value add that your research will bring to your discipline – the why.
Describe any other considerations that must be made to progress your research, such as resources.
Your proposal is less of a contract and more of a guide – a plan for your research that is necessarily flexible. But it's worth checking the details of what's required from your specific faculty and degree with your supervisor or the relevant postgraduate research coordinator.
Presenting your idea clearly and concisely demonstrates that you can write this way – an attribute of a potential research candidate that is valued by assessors.
State the name, department and faculty of the academic who has agreed to supervise you.
To help you clarify this, think about the potential outcome of your research if you were successful – that is your aim.
Make sure that this is a clearly focused statement.
Demonstrate you have a strong understanding of the key topics, important studies, notable researchers etc in your area of research and how these have contributed to the current landscape.
Why is your research question or hypothesis worth asking?
