IELTS Writing Task 1 Coach
Task 1 is a 20-minute, minimum-150-word academic report. It is not an essay — no opinion, no personal examples. The task is to select, describe, and compare the most significant features of the given visual(s).
Use this when
- The user shares a Task 1 prompt (graph, chart, table, diagram, process, map) and wants a draft or critique.
- The user wants a band estimate with actionable feedback.
- The user asks how to write an overview, select key features, or describe trends.
- The user wants vocabulary or grammar for data description.
Do not use this when
- The user is working on Task 2 (argumentative essays). Use
ielts-writing-task2.
- The user is asking about Speaking. Use
ielts-speaking-coach.
- The user is studying for General Training Task 1 (letter writing) — note the difference if they mention it.
Band Descriptors (Task 1)
Scores are averaged equally across four criteria. Task 2 is weighted more heavily in the final Writing band, but Task 1 is still significant.
Full band-by-band reference (bands 5–9, all four Task 1 criteria) with links to the official IELTS descriptors: references/ielts-band-descriptors.md. Consult it before assigning a band so scoring stays anchored to the public criteria, not impression.
Task Achievement (TA)
| Band |
Descriptor |
| 9 |
Fully satisfies all requirements; clear, fully developed overview; key features skilfully selected, highlighted, and illustrated; data accurately described |
| 8 |
Covers requirements; presents and highlights key features clearly with appropriate selection; data accurately described; summary adequate, accurate, and relevant |
| 7 |
Covers requirements; presents key features with some inaccuracy; covers key features but may be over-detailed or miss minor points |
| 6 |
Addresses most requirements; presents overview with information appropriately selected; may contain inaccuracies; detail may be irrelevant |
| 5 |
Generally addresses requirements but format may be inappropriate; unclear overview; may include irrelevant, inappropriate, or inaccurate content |
| 4 |
Partially addresses requirements; key features inadequately covered; may be inaccurate or format inappropriate |
| 3 |
Fails to address requirements; no overview; limited or irrelevant content |
Coherence and Cohesion (CC)
| Band |
Descriptor |
| 9 |
Cohesion attracts no attention; paragraphing managed skilfully |
| 8 |
Sequences information logically; manages all aspects of cohesion well; paragraphing sufficient and appropriate |
| 7 |
Logically organises information; good overall progression; uses cohesive devices including reference and substitution appropriately, though may occasionally over/under-use; clear central topic per paragraph |
| 6 |
Arranges information coherently; adequate overall progression; uses cohesive devices effectively but cohesion may be faulty or mechanical; may not always use referencing clearly |
| 5 |
Some organisation but lacks overall progression; limited cohesive devices, not always accurately used; repetitive due to lack of referencing |
| 4 |
Information presented but no clear progression; some basic cohesive devices, may be inaccurate or repetitive; inadequate or absent paragraphing |

| 8 |
Wide vocabulary, fluently and flexibly used to convey precise meanings; skilful use of uncommon items; rare errors in spelling or word formation |
| 7 |
Sufficient range for flexibility and precision; less common items used with some awareness of style and collocation; occasional errors in word choice, spelling, or word formation |

| 5 |
Limited but minimally adequate vocabulary; noticeable spelling or word formation errors that may cause some difficulty |
| 4 |
Basic vocabulary only, possibly repetitive or inappropriate; limited word formation and spelling control; errors may cause strain |
| 3 |

Mix of simple and complex forms; some grammar and punctuation errors but rarely impeding communication |
| 5 |
Limited range; complex sentence attempts tend to be less accurate than simple ones; frequent grammatical errors; faulty punctuation |
| 4 |
Very limited structures; rare subordinate clauses; errors predominate; punctuation often faulty |
| 3 |
Sentence forms attempted but errors and punctuation problems predominate and distort meaning |
Workflow
Step 1 — Identify the visual type and data
Determine:
- Type: line graph / bar chart / pie chart / table / map (before & after) / process diagram / multiple charts
- Time dimension: static snapshot vs. change over time
- Key entities: what is being compared (countries, years, categories, stages)
- Overall trend or pattern: what is the single most important thing the data shows
Step 2 — Plan the response structure
Standard Task 1 structure (4 paragraphs):
- Introduction — Paraphrase the prompt (do NOT copy it). One or two sentences describing what the visual shows.
- Overview — The 2–3 most significant features. No data. This is the most critical paragraph for Task Achievement.
- Body paragraph 1 — Specific details with data for the first main group/trend.
- Body paragraph 2 — Specific details with data for the second main group/trend.
For processes or maps, adapt to: Introduction → Overview of stages/changes → Detailed description of each phase.
Step 3 — Draft or critique
When drafting:
- Write the overview before any data — it forces selection of key features.
- Use comparative and trend language precisely.
- Avoid mechanical listing of every data point.
- Stay at ≥150 words (examiners penalise under-length).
When critiquing a user's response:
- Check for presence and quality of overview first.
- Check that key features (not all features) are selected.
- Check data accuracy against the prompt.
- Then evaluate CC, LR, GRA.
Step 4 — Score and feedback
Report a band estimate for each criterion and an overall estimated band:
Task Achievement: X / 9
Coherence & Cohesion: X / 9
Lexical Resource: X / 9
Grammatical Range: X / 9
Estimated overall: X.X / 9
For each criterion below 7, give 2–3 specific, actionable improvements with examples drawn from the user's actual text.
Key language banks
Describing trends (line graphs, time series)
- Increase: rose, climbed, grew, surged, jumped, increased, went up
- Decrease: fell, dropped, declined, decreased, plummeted, dipped
- Stability: remained stable, levelled off, plateaued, stayed constant
- Fluctuation: fluctuated, varied, oscillated
- Peak/trough: reached a peak of, hit a high of, bottomed out at, reached a low of
Adverbs: sharply, steeply, dramatically, significantly, gradually, steadily, marginally, slightly
Comparing (bar charts, tables, pie charts)
- X was significantly higher than Y
- The proportion of X was roughly double that of Y
- X accounted for the largest share at Z%
- In contrast / by comparison / whereas / while
Describing processes
- First / Initially / To begin with
- Subsequently / Following this / The next stage involves
- Finally / Ultimately / The process concludes with
- is converted into / is fed into / passes through / undergoes
Describing maps
- To the north/south/east/west of
- Adjacent to / opposite / alongside
- was replaced by / was demolished / a new X was constructed
- The area to the left underwent significant development
Common mistakes to flag
- No overview — biggest single TA error; must be there and must be general (no numbers).
- Copied introduction — paraphrase the prompt, do not reproduce it.
- Describing every data point — select the most significant; don't just list.
- Inaccurate data — misreading values; always recheck numbers against the prompt.
- Personal opinion — "I think this shows…" has no place in Task 1.
- Under 150 words — automatic penalty to TA.
Output format
When producing a model answer:
- Label each paragraph (Introduction / Overview / Body 1 / Body 2) so the user can see the structure.
- Provide a word count.
- After the answer, give a brief note on the key structural and language choices made.
When giving feedback on the user's response:
- Quote the user's original text when identifying issues.
- Provide a corrected or improved version of the problem sentence.
- End with the scored table and top priorities.
