Task 1 Process Diagrams for the IELTS Exam — Indian candidates

5% of the IELTS test plan. Process diagrams are a sub-type of Academic Task 1 — describing a flow, cycle, or manufacturing process step-by-step. Calibrated for Indian candidates.

If you have already studied this content from a textbook, you know the material. The question this page answers is whether you can apply it under exam conditions. Task 1 Process Diagrams sits at roughly 5% of the International English Language Testing System content distribution — Process diagrams appear in roughly 15% of Academic Task 1 tests. They require passive voice and sequencing language ("In the first stage…, This is then transferred to…") rather than the trend vocabulary used for charts. In 2023, the published band 7-or-higher rate for IELTS candidates in India was 32% (IELTS Test-Taker Performance — Indian Academic candidates). For Indian candidates preparing for IELTS, the calibration of study to local context matters: India is the world's largest single-country exam market. Most national exams (JEE, NEET, GATE, CUET) are conducted by NTA in English plus regional language editions.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

!Using past tense ("was transferred") instead of present passive ("is transferred")
!Listing steps without grouping into logical phases
!Forgetting to write the overview
!Copying labels verbatim from the diagram instead of paraphrasing

Study tips

1Memorize 10 sequencing phrases ("Firstly,", "In the next stage,", "Subsequently,").
2Drill the present-simple passive voice ("is heated to 200°C", "is then poured into…").
3Practice grouping steps into phases (e.g., preparation → transformation → packaging).
4Always write the 2-sentence overview describing how many stages and the start/end product.
5For candidates in India, IELTS test windows are typically denser in the spring; book test centres in metro cities (Delhi, Mumbai, Bengaluru, Chennai, Kolkata) early to secure preferred dates.

In an Academic Task 1 process diagram, the dominant verb form is:
- APast simple active

- DFuture passive
Why this answer?
Process diagrams describe a generic, repeatable process. The present simple passive ("is heated", "is mixed") is the correct form because the agent (who heats it) is irrelevant.
