IELTS Academic Task 1 word count and practice scores: October 2026 study

01

What question does this study answer?

Academic Task 1 asks the writer to select and describe information from a visual input. A longer response can contain more comparisons, but it can also repeat details or spend words on information that does not help the reader understand the main features. Length is therefore a useful descriptive variable, rather than a direct measure of task quality.

The official task has a 150-word minimum. That requirement answers how much writing the task expects; it does not identify the response length associated with the highest estimate in an online practice sample. We keep those two questions separate throughout this study.

This dataset does not record the visual-input category in a standardized research field. Graphs, tables, maps and processes may be mixed in the cohort. Different tasks can require different amounts of explanation. We cannot use the length groups to decide whether a particular chart should receive a longer answer.

02

How long were the evaluated responses?

The middle half of responses contained 163–208 words. The mean overall estimate was 5.71 and the median was 5.5. These are separate descriptive summaries of this cohort, rather than recommended writing targets.

676 responses met the 150-word minimum under our whitespace counting method.

The lower tail is limited by the product’s submission checks. The recent evaluated cohort contains few or no responses below the official task minimum. It cannot establish the score consequences of writing substantially under length.

03

Do longer responses receive higher practice estimates?

Across the displayed length groups, the means do not form a consistently increasing sequence.

The table shows separate groups of observed responses. It does not follow one answer as words are added or removed. Accounts can appear in more than one group, so the contributing-account column should not be summed.

Groups require at least 20 responses and 10 accounts. Word bands are descriptive; compliance with the official minimum is reported separately.

04

Does the pattern survive one response per writer?

With the first retained response per account and task, the sample contains 372 responses. Its median length is 181 words and its rank correlation is 0.179, compared with 0.165 in the full retained cohort.

Spearman’s correlation compares ranks, using average ranks for ties. A value near zero indicates little monotonic association in this sample. It does not rule out task-specific relationships, and it is not a test of whether an editing intervention works.

05

How can learners and teachers use this evidence?

For a learner, the defensible use of these results is to review what the extra words accomplish. An additional comparison may improve coverage; another sentence repeating the same trend may not. Use the task and the reader’s information needs to decide what stays in a revision.

For a teacher, the distributions provide a way to discuss editing without presenting a single ideal word count. Compare two responses to the same visual input, identify the overview and key comparisons, and ask whether every detail earns its place. This is a teaching suggestion, not an intervention tested by this dataset.

A stronger follow-up would classify visual-input types, obtain independent task-coverage judgments and evaluate matched drafts under one fixed scoring setup. Until then, a peak in one length group should not become a universal word-count recommendation.

Methods

How this report was prepared

The study uses the latest completed AI evaluation for each eligible submission in the 22 August–5 October 2026 window. Site, task, score and word-count checks precede normalized exact-text deduplication. Accounts contributing more than 50 distinct retained responses in the window are excluded by an exploratory audit rule.

Detailed primary cohorts require 100 responses and 30 accounts. Length and score bins require 20 responses and 10 accounts. The first-response-per-account-and-task analysis is a sensitivity check; it can contain fewer responses than the primary cohort. Account counts across tasks and bins can overlap.

The source does not identify every evaluator model and prompt version, verify examination conditions, or provide independent examiner scores. Lightly edited duplicates and external assistance may remain. Differences describe this practice sample and scoring system; they do not demonstrate official proficiency, causal improvement or universal task difficulty.

Computation and drafting were assisted by AI. This release has no independent human examiner validation, pedagogical review or journal peer review. Only aggregates are published; raw writing, prompts, feedback and learner identifiers are excluded.

Questions about the findings

Is the median word count an ideal target?

No. It describes this practice sample. Follow the task requirements and use the response’s coverage, development and clarity to judge what to include.

Does a higher mean in a longer group prove that adding words helps?

No. The groups differ in writers, prompts and practice conditions. This study does not compare matched edited versions of the same answer.
