IELTS Process Diagram Sample

This page illustrates an example of an IELTS process. Occasionally you will have to desribe a process in the test instead of a graph. 

Although this type of diagram is less common to see in the test, it is still important to have an understanding of how to tackle this should it arise.

This is an example of the process of making bricks. A sample answer is below the diagram.

The Brick Manufacturing Process

IELTS Process Model Answer

The diagram explains the way in which bricks are made for the building industry. Overall, there are seven stages in the process, beginning with the digging up of clay and culminating in delivery.

To begin, the clay used to make the bricks is dug up from the ground by a large digger. This clay is then placed onto a metal grid, which is used to break up the clay into smaller pieces. A roller assists in this process. 

Following this, sand and water are added to the clay, and this mixture is turned into bricks by either placing it into a mould or using a wire cutter. Next, these bricks are placed in an oven to dry for 24 – 48 hours. 

In the subsequent stage, the bricks go through a heating and cooling process. They are heated in a kiln at a moderate and then a high temperature (ranging from 200c to 1300c), followed by a cooling process in a chamber for 2 – 3 days. Finally, the bricks are packed and delivered to their destinations.

This is a good answer as it covers the requirements of the task.

The topic of the IELTS process diagram is first introduced and then an overview is given. You should give an overview for all academic task 1 responses, not just graphs.

In this case, here is the overview:

Overall, there are seven stages in the process, beginning with the digging up of clay and culminating in delivery.

The answer is well-structured, covering each stage of the process in turn. 

It uses the passive voice which is needed when you describe a process diagram in IELTS but you are not referring to who is doing the action. Here are some examples of the passive used:

  • clay is then placed
  • which is used to 
  • sand and water are added
  • bricks are placed  
  • They are heated
