How many words should IELTS Writing Task 1 be?

At least 150 words, with 160 to 190 being a comfortable target. Spend about 20 minutes on it, leaving 40 for Task 2. Under-length answers are penalised under Task Achievement, and there is no benefit to a 250-word Task 1 beyond the extra chances it gives you to make errors.

Do I need a conclusion in Academic Writing Task 1?

No. Task 1 needs an overview, which is not the same thing. An overview states the main trends or the most striking features of the data and belongs near the start, immediately after the introduction, or at the end if you prefer. A conclusion that draws inferences beyond the data is not required and can hurt you.

Should I give my opinion in Academic Task 1?

No. Academic Task 1 asks you to report and compare what the data shows. Explaining why a trend happened, or saying whether it is good, goes outside the task and is penalised under Task Achievement. Save opinion for Task 2.

What is the most common reason for losing marks in Task 1?

Missing or burying the overview. It is the single feature most directly tied to the Task Achievement band, and a Task 1 answer with no clear overview is capped regardless of how accurate the rest of the description is. Signpost it explicitly with a phrase such as overall.

IELTS Writing Task 1: a step-by-step guide with Band 9 examples

How to structure IELTS Academic Writing Task 1: how to write a high-scoring overview, describe data accurately, and reach Band 9, with a full model answer.

In IELTS Academic Writing Task 1 you describe a visual, a line graph, bar chart, pie chart, table, map or process diagram, in at least 150 words in about 20 minutes. In General Training, Task 1 is a letter instead. This guide focuses on the Academic data task and gives you a repeatable structure that reaches Band 7+ every time, plus a Band 9 model answer.

What Task 1 is really testing

You're marked on four criteria: Task Achievement (did you select and report the key features with accurate data?), Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. You are NOT asked for opinions or reasons, just an accurate, well-organised description of what the data shows.

A four-paragraph structure that works

Introduction: paraphrase the question (say what the visual shows). One sentence.
Overview. The single most important paragraph: 2-3 sentences naming the biggest trends or differences, with NO specific numbers.
Body 1: describe the first group of key features with data.
Body 2: describe the remaining key features with data.

The overview is where marks are won or lost

Without a clear overview you are capped at Band 5 for Task Achievement, no matter how accurate your figures are. The overview zooms out: what's the highest, the lowest, the overall direction, the biggest gap? Signal it with "Overall, …" so the examiner can't miss it.

Language for describing data

Increase: rose, climbed, surged, grew, went up.
Decrease: fell, declined, dropped, plummeted, decreased.
Stability: remained stable, held steady, plateaued, levelled off.
Degree + speed: a sharp rise, a gradual decline, a slight increase, a dramatic fall.
Vary your grammar: "Sales rose sharply" (verb + adverb) and "There was a sharp rise in sales" (adjective + noun).

Band 9 model answer (line graph: coffee vs tea consumption)

Introduction: "The line graph illustrates how much coffee and tea were consumed per person in a European country between 2000 and 2020."

Overview: "Overall, coffee consumption rose steadily across the period and overtook tea, which had been the more popular drink at the start but declined consistently by the end."

Body 1: "In 2000, tea was clearly dominant at around 4 kg per person, compared with just 2 kg for coffee. Tea then fell gradually, dipping below 3 kg by 2010 and reaching roughly 2 kg by 2020."

Body 2: "Coffee, meanwhile, climbed steadily throughout, passing tea at approximately 3 kg around 2012 before peaking at about 4.5 kg in 2020. More than double its starting figure."

Timing and word count

Spend no more than 20 minutes on Task 1 and leave 40 for Task 2 (it's worth twice the marks). Write at least 150 words, under-length answers are penalised, but don't pad; examiners reward selection of key features, not every tiny detail.

Task 1 vs Task 2: don't confuse them

Task 1 is a factual description (150+ words, 20 minutes); Task 2 is an argumentative essay (250+ words, 40 minutes) worth double. If you're short on time, protect Task 2. A strong essay lifts your Writing band more than a perfect Task 1.

Practise with instant band feedback

Task 1 improves fastest when you write under time and get specific feedback on your overview and data accuracy. On IELTSVega you can practise real Academic Task 1 charts (and General Training letters), then get instant AI band scoring against all four criteria, so you know exactly which paragraph is costing you marks before test day.
