IELTS Writing band descriptors should help you make a teaching decision. A student with an underdeveloped argument needs to see where the explanation breaks down and practise repairing it.
Use the descriptors as a reference for interpreting a complete response. Then translate your assessment into language the learner can act on. A classroom estimate should always be presented as provisional, not as an official IELTS result.
Understand what the four criteria assess
The official Writing band descriptors (opens in a new tab) describe performance across four criteria. Task 1 and Task 2 have separate task-focused descriptors.
| Criterion | A question to guide your reading |
|---|---|
| Task Achievement, Task 1 | Has the writer fulfilled the particular reporting or letter-writing task? |
| Task Response, Task 2 | Has the writer answered the question and developed a relevant position? |
| Coherence and Cohesion | Can the reader follow the organisation and connections? |
| Lexical Resource | Are vocabulary choices sufficiently varied, precise and appropriate? |
| Grammatical Range and Accuracy | Does the writer control a useful variety of sentence structures? |
Task Achievement and Task Response occupy the same assessment slot, depending on the task; the table therefore represents four criteria for each response, not five.
The criteria are equally weighted within each task, while the tasks are assessed independently. See IELTS scoring in detail (opens in a new tab). Avoid treating grammatical correctness as the whole assessment.
Read the task before you read the answer
Write down what the prompt actually requires. For Academic Task 1, inspect the visual carefully. For General Training Task 1, identify the recipient, purpose and required information. For Task 2, identify every question or instruction that needs a response.
This matters because fluent writing can distract a reader from missing content. An elegant paragraph about the benefits of exercise may not answer a question about whether employers should provide exercise facilities.
Keep a simple task map visible: “The response must address ___ and ___.” Check accomplished-sounding writing against those requirements.
Collect evidence before choosing a band
Read the whole response once for meaning without correcting it. On a second reading, record examples under the four criteria. Include strengths as well as limitations.
Do not begin with a number and search for comments that justify it. Ask what the writing shows repeatedly, what occurs only once and where your interpretation remains uncertain.
“Paragraph 2 gives a reason but never explains how it produces the claimed benefit” is more useful than “needs development”. “The pronoun ‘this’ has two possible referents” is more useful than “cohesion problem”.
A short excerpt can support a teaching diagnosis, but it cannot demonstrate the full performance needed for a defensible overall estimate.
Work through an illustrative assessment
Consider this original teaching excerpt from a practice essay about university lectures:
Universities should offer some lectures online because this is convenient. For example, students can watch them at home. This is good for students because they have many responsibilities. Moreover, online teaching is a revolutionary educational phenomenon. It make learning better.
Do not assign a band to this excerpt. Use it to practise separating observations.
| Observation | Teaching interpretation | Next task |
|---|---|---|
| Convenience is asserted, but the benefit remains broad | The reason needs a clearer explanation | Identify a specific responsibility and explain the effect |
| “This” is used repeatedly | The links could be made more explicit | Replace one instance with a precise noun phrase |
| An elaborate phrase adds little meaning | Vocabulary needs to serve the argument | Replace it with a concrete benefit |
| “It make” is inaccurate | Subject–verb agreement needs attention | Correct it, then check three new sentences |
A possible revision is:
Universities could make some lectures available online so that students with caring responsibilities can study more flexibly. A student who must collect a child from school, for example, could watch a recorded lecture later that evening.
Ask what improved and what still needs work. The revision explains one advantage more precisely, but a complete essay would still need an appropriate overall answer and development. One repaired paragraph is evidence of a successful revision, not proof of a particular band.
Turn assessment language into teachable objectives
Choose an objective that a learner can demonstrate in a fresh task. “Improve coherence” is too broad for a single lesson. “Organise a paragraph so that each supporting sentence develops its main claim” gives you something observable.
Try a paragraph-order activity. Write four original sentences: a claim, a reason, an example and an unrelated statement. Students select and sequence the useful sentences, then explain why they excluded the distractor. Their explanation reveals whether they understand the argument's direction.
For lexical precision, ask students to replace vague words in their own work. A phrase such as “a bad effect” requires a decision: higher costs, fewer opportunities or longer delays? Students should choose the meaning before consulting a dictionary.
For grammar, use the learner's intended relationship. If two ideas contrast, practise expressing that contrast in more than one accurate way. Return to a new paragraph afterwards to check whether the construction is available beyond the exercise.
For a broader teaching sequence, read how to teach IELTS Writing Task 1 and Task 2.
Use adjacent bands without inventing shortcuts
Read the relevant descriptors above and below a tentative estimate. Consider the whole pattern of evidence. For example, the published Task 2 descriptors distinguish levels partly through how thoroughly an argument is developed and how consistently language is controlled.
Avoid rules such as “three complex sentences equal Band 7” or “one unusual word earns a vocabulary point”. The published assessment scale (opens in a new tab) evaluates performance across a response; it is not a points checklist for isolated features.
When evidence sits between your interpretations, record the uncertainty and seek a second reading. Clear reasoning is more useful than pretending a classroom judgement is exact.
Practise consistency with another teacher
Select two complete practice responses. Each teacher reads them independently, records evidence and makes a provisional judgement. Compare the evidence before discussing the numbers.
When you disagree, locate the cause. Did one teacher overlook part of the prompt? Did a few sophisticated words create an overly positive impression? Did one repeated error dominate the judgement?
Record the discussion and revisit it with fresh work. Averaging two numbers does not resolve the disagreement.
Official samples offer useful reference material. Start with the IELTS Academic sample questions and Writing resources (opens in a new tab), checking which materials include examiner commentary.
Give feedback that leads to a second attempt
A useful feedback note contains evidence, an action and a check:
Your second paragraph says online lectures save time, but does not explain whose time or how. Add one specific situation. Then ask a partner to state the benefit without further explanation from you.
Ask students to submit the original and revised versions together, with a sentence explaining their change. Later, check the same skill in a new response. Our guide to giving effective feedback to IELTS students develops this process.

Frequently asked questions
Can I use the descriptors with lower-level learners?
Yes, but select accessible language and a narrow focus. Show students one concrete feature in their work rather than giving them the entire document to interpret unaided.
Should I give a band for every paragraph?
A paragraph is useful for focused feedback. It does not provide the same evidence as a complete task response. Describe what it demonstrates and reserve broader estimates for suitable complete work.
Should I correct every error before estimating performance?
Read the original response before editing it. Otherwise, you risk judging a version partly created by the teacher. Keep assessment, explanation and student revision as distinct stages.
