Task 1 Process Diagrams for the IELTS Exam — California 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 Californian 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. Pass rates for the IELTS are published annually by the awarding body and vary by cohort and locale. For California candidates preparing for IELTS, the calibration of study to local context matters: California is the largest U.S. testing market for NCLEX, MCAT, SAT, and ACT. The CA Board of Registered Nursing has notoriously long endorsement timelines (8–14 weeks).

Pass rates for IELTS (California, USA) are published periodically by the awarding body.

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 NCLEX-RN: the California Board of Registered Nursing requires LiveScan fingerprinting before ATT release; book early because LiveScan vendors fill 2–3 weeks out.
  • 6For MCAT/SAT/ACT: California universities are test-blind for SAT/ACT undergraduate admission as of 2024; verify whether your target medical/grad programs still require MCAT/GRE.
  • 7For CDL: California has its own "California Special Requirements" addendum on top of FMCSA; review the CA Commercial Driver Handbook before sitting the written test.

    In an Academic Task 1 process diagram, the dominant verb form is:

    • APast simple active
    • BPresent simple active
    • CPresent simple passiveCorrect
    • 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.
