For an IELTS diagram, you need an introduction and overall paragraph containing the main features of the diagram or process in your report. The overview is one of the most important parts of your report if you are aiming for band score 6 and above. See below for an example of how to write the introduction and overview for the process shown in the picture.
Introduction and Overview
- paraphrase the information given about the diagram for the introduction
- choose the main stages for the overview ( eggs, water, tadpole, land, adult frogs)
