To describe a PTE line graph well, lead with the trend rising, falling, fluctuating or steady then name the start and end values, the peak and the lowest point, and close with the overall direction. Do it in about 40 seconds, fluently and in your own words. A flexible framework scores; a memorised script gets flagged under the 2025 marking standard.
How is a line graph Describe Image scored?
Describe Image scores three things at once: content (the key data you mention), oral fluency (smooth, steady speech) and pronunciation. For a line graph, content means the trend plus the standout points — so cover the shape of the line and a few real figures, fluently, and you score across all three.
The timing matters too. You get 25 seconds to study the image and plan, then up to 40 seconds to speak after the tone — so use the prep window to spot the trend and pick your figures before you start talking.

Crucially, you don’t need every data point. You need the important ones the trend, the extremes, and the start and end delivered clearly. Trying to read every value usually costs fluency without adding content.
What’s a flexible template for a line graph?
Use a four-move framework you adapt to each graph: (1) say what it shows, (2) lead with the trend, (3) give the key figures start, end, peak, low, (4) close with the overall direction. Swap the wording each time so it’s your description, not a memorised frame.
- Identify. ‘This line graph shows [topic] from [start] to [end].’
- Lead with the trend. ‘The most striking feature is [the sharp rise / steady fall / fluctuation].’
- Give key figures. ‘It begins at [value], peaks at [value] in [point], and ends at [value].’
- Close with direction. ‘Overall, the trend is clearly [upward / downward / volatile].’
Pearson is explicit: memorised, templated sentences can be marked 0 for content and if content scores zero, your fluency and pronunciation aren’t scored either. A fixed, word-for-word opener used on every graph reads as a template. Keep the four moves, but change the words to fit the graph in front of you.

What does a full sample answer sound like?
Here’s the framework applied to a graph showing electricity use over a year. Notice it leads with the trend, names four real points, and closes with direction all in about 40 seconds of natural speech.
“This line graph shows household electricity use across one year. The most striking feature is a clear seasonal pattern, with a sharp peak in winter. Usage starts at around 300 units in spring, dips to its lowest of about 200 in summer, then rises steeply to a peak of roughly 500 units in winter. Overall, the trend shows electricity consumption rising significantly in the colder months.”
That’s six sentences, four data points, one clear trend adaptable to any line graph by swapping the topic, figures and shape.
What trend vocabulary actually scores?
Use precise movement words rather than repeating ‘goes up’ and ‘goes down’. Strong verbs and adverbs signal natural English and lift your content and fluency together. Match the word to the steepness of the change.
| Movement | Use these words |
|---|---|
| Rises | increase, rise, climb, grow, surge, soar (sharp) |
| Falls | decrease, fall, decline, drop, plummet (sharp), dip (small) |
| No clear trend | fluctuate, vary, remain stable, plateau, level off |
| Extremes | peak (highest), reach a low / trough (lowest) |
Pair them with adverbs sharply, steadily, gradually, significantly to show how fast the change happened.
What mistakes cap your line-graph marks?
The big ones are: reciting a memorised opener, trying to read every data point (which kills fluency), going silent, and finishing too early. Speak for the full ~40 seconds, lead with the trend, and keep your pace steady even if you miss a number.
- Lead with the trend and the standout point
- Name 3–4 real figures, not every value
- Speak fluently for the full ~40 seconds
- A memorised, identical opener every time
- Reading every data point and losing fluency
- Long pauses or stopping early

Frequently asked questions
-
How do you describe a line graph in PTE?
Lead with the trend (rising, falling or fluctuating), then name the start, end, peak and lowest points with real figures, and close with the overall direction all in about 40 seconds.
-
Should I memorise a line-graph template?
No. A fixed, memorised script scores poorly under the 2025 marking standard. Use a flexible four-move framework you adapt to each graph in your own words.
-
How long should a Describe Image answer be?
About 40 seconds of continuous speech. Speak for the full time finishing early or pausing too long costs fluency marks.
-
Do I need to mention every data point on a line graph?
No. Cover the trend plus the key points start, end, peak and lowest. Reading every value usually hurts your fluency without adding content.
-
What vocabulary should I use for a line graph?
Precise movement words: increase, rise, climb, surge, decline, plummet, fluctuate, plateau, peak and trough — paired with adverbs like sharply, steadily and gradually.
-
Is content or fluency more important in Describe Image?
Both matter. You need the key data (content) delivered with smooth, clear speech (fluency and pronunciation) — a strong answer needs all three.
