Overview

The first thing that candidates should do for answering IELTS Academic task 1 is to formulate an overview. This overview must include all the steps needed throughout a process along with the first and ultimate step.

For instance, ‘The process chart shows the production of cheese, with a total of X steps, beginning with cows grazing and ending with the delivery of packed cheese’. Students can also mention the final result of the production. In case there are different types of processes involved, one can mention them in the overview along with various stages required.Let’s say the process diagram shows that the final result is tea. In this case, the overview could be: ‘This process chart demonstrates the production of five different types of tea, from growing tea plants to packaging. There is also another process diagram that shows six steps for the production of coffee beans.’If the chart illustrates a hydroelectric process, one can begin the following way: ‘Power generation starts with the sun heating up the water bodies, and the process ends with the hydroelectricity being supplied into homes, schools, factories and hospitals for consumption.’However, make sure to avoid copying the language provided in the process diagram word by word. You are allowed to use some of those words that are present in the process chart. 

Grammatical Accuracy and Range

Process diagram task of IELTS tests a candidate’s ability to use active and passive voice. There are certain verbs that cannot be used for passive voice. Thus, to ascertain which voice is appropriate for describing a process chart task, one needs to ask who is doing the action. Depending on the type of process task, it can be a worker, a machine, nature or something else.In addition, it is crucial to use relative clauses such as ‘after that’ to ensure a smooth transition.

Coherence and Cohesion

To keep your response free from repetitive use of words and phrases, it is ideal to use object pronouns. Object pronouns are specifically helpful in eliminating the chances of repetition.For instance, you can use phrases like ‘following this’, ‘following’, ‘after this’, ‘followed by’, ‘first, second and finally’, ‘once this step is completed’ and more to avoid repetition and thereby establish cohesion and flow. 

Use of Appropriate Verbs

Candidates can make use of a variety of verbs while describing the IELTS process diagram. Here’s a list of verbs along with the suitable prepositions that one can employ:

Water, light and carbon dioxide enters into the chloroplast. After this, water enters the thylakoids. In thesecond step, carbon dioxide gets incorporated into the Calvin cycle. Subsequently, chloroplast produces sugar and oxygen in the third step.’For describing a cycle of repetition, you are required to use the following process chart vocabulary:

Samples of Process Diagram Task Questions 

The Writing section is, indeed, an important as well as challenging part of the IELTS test. The following sections illustrate a sample IELTS process chart task to help students get an idea about how to formulate the most appropriate answer for this task. Question: The image below illustrates the recycling process of discarded glass bottles. Provide a summary of the information by mentioning the main features and make appropriate comparisons wherever relevant. Here’s how you should chalk out a structure for your response:

  • Paraphrase: Recycling process of discarded glass bottles
  • Overview: State the three stages that go into recycling waste glass bottles
  • Paragraph 3: Elaborate on the first and second stages of the recycling process
  • Paragraph 4: Sent to glass factories, crushed by machines, the pieces are then burnt, molten glass and newly manufactured liquid glass coupled 
  • Paragraph 5: Discuss the final stage of the glass recycling process. 

What to Write?

Once you are done with creating the blueprint for your answer, proceed to draft the response. Here’s how the response should be:This diagram depicts the process of recycling discarded glass bottles.We can find out from the diagram that there are three main stages involved with the recycling of glass bottles, starting with the collection of wasted glass bottles, recycling of the bottles and finally the delivery of new products. At first, wasted and discarded bottles are collected at a particular point. They are transported to the nearby recycling centres by truck. After this, high-pressure water is used to clean these bottles and remove the dust and other objects. Once cleaned, these bottles are classified into three types on the basis of colour. These bottles are then sent to a glass factory, where they are crushed into finer pieces. The process continues in a furnace, wherein these crushed particles are burned at a high temperature until they become molten glass. Afterwards, this recycled glass is coupled with new liquid glass to manufacture recycled bottles. The newly manufactured bottles are filled with different kinds of drinks. The process concludes after these bottles are sent to the markets.
