On IELTS Writing Task 1, you’ll need to describe a graphic. Sometimes, this can be a type of chart. Other times, it will be a process diagram. So how do you know what process diagram vocabulary IELTS examiners are looking for? That’s where Magoosh comes in!

In this post, we’ll look at words and phrases you can use to describe processes on IELTS Academic Writing Task 1. (And for additional tips on IELTS vocabulary, check out our collection of the best IELTS Writing tips and Task 1 Language and Vocabulary guide!)

What is a Process Diagram on the IELTS?

A process diagram is an illustration that shows you how something is done. It could be anything from the creation of a product to the recycling cycle (as in this IELTS Task 1 process example!)

Generally, you’ll find two types of process questions. The first is a manufacturing process: something that humans do. The second is a natural process: something that occurs in nature.

Within your essay, you won’t need to come up with deep insights or hypotheses about the diagram that you’re looking at. Instead, you’ll simply need to follow the prompt, describing what you see. This can be surprisingly complex, so practice is crucial.

No matter what type of process the prompt asks you to write about, you can use the same kinds of process vocabulary IELTS words and phrases in your response!
