The Task Achievement Criterion is one of the official scoring criteria used in IELTS Writing Task 1. It measures how well you complete the task, cover the required information, and present key features clearly and accurately.

In simple terms, it asks:

Did you do what the question asked you to do?

Where It Applies

The Task Achievement Criterion is used mainly for:

• Writing Task 1 Academic
• Writing Task 1 General Training (with task-specific expectations)

For Writing Task 2, the related criterion is usually called Task Response.

What Examiners Look For

Examiners assess whether you:

• Address all parts of the task
• Present a clear overview (Academic Task 1)
• Select and report key features
• Support details with accurate data or relevant information
• Avoid irrelevant information
• Write enough to complete the task properly

Academic Task 1 Focus

In charts, graphs, tables, maps, or processes, strong Task Achievement means:

• Summarizing main trends
• Comparing important data
• Highlighting significant changes
• Including a clear overview
• Choosing key details, not every number

Example

If a graph shows sales from 2010–2020:

Weak response:

Lists random numbers only.

Strong response:

Explains overall rise, key peaks, declines, and major comparisons.

General Training Task 1 Focus

In letters, strong Task Achievement means:

• Responding to all bullet points
• Using suitable tone (formal / semi-formal / informal)
• Giving enough explanation
• Maintaining purpose clearly

Example

If the letter asks you to:

• Explain a problem
• Apologize
• Request action

A high-scoring answer addresses all three clearly.

Band Score Meaning (Simplified)

Higher Bands Often Show:

• Fully addresses task
• Clear overview or purpose
• Well-selected details
• Accurate information
• Relevant content throughout

Lower Bands Often Show:

• Missing key parts
• No overview
• Too little support
• Irrelevant details
• Incomplete response

Common Mistakes Candidates Make

No Overview (Academic)

This can strongly limit score.

Describing Every Number

Too much detail, weak summary.

Missing Bullet Points (GT Letter)

Unanswered parts reduce marks.

Going Off Topic

Ideas not connected to task.

Underlength Response

Too short to develop properly.

High-Scoring Strategies

Analyze the Task First

Know exactly what is required.

Identify Key Features

Choose biggest trends, highest/lowest points, major comparisons.

Write a Clear Overview

Usually after introduction or before details.

Group Information Logically

Do not report data randomly.

Cover Every Requirement

Especially in letter prompts.

Example Academic Structure

• Introduction
• Overview
• Detail Paragraph 1
• Detail Paragraph 2

Example General Letter Structure

• Greeting
• Purpose
• Bullet Point 1
• Bullet Point 2
• Bullet Point 3
• Closing

Why It Matters

Even strong grammar cannot fully compensate if you fail the task itself.

You can write accurate English but still lose marks if the response does not answer the question properly.

Quick Tips

• Read the prompt twice.
• Ask: what must I include?
• Always write an overview for Academic Task 1.
• Cover all bullet points in letters.
• Relevance beats unnecessary length.
