PISA test score decline
Financial Times's line chart drew 2.4M views on X: 5.2x its typical post and #3 of 25 Financial Times charts we track by views. Read Oct 10, 2026.
Two extraordinary charts from today’s PISA test results:
Why it spread
This post spread because it paired a clear, alarming finding about international test score decline with strong engagement, earning 10,920 likes, 2,662 reposts, 661 quotes, 3,510 saves, and 2,370,397 views, while the author's independent status and the post's high quote rate helped drive conversation.
What worked
- The post text frames the chart as showing a sustained collapse in school test scores, not just a Covid effect, which gives the data a urgent, newsworthy angle.
- The chart type is a line chart, which clearly shows the downward trend over time and makes the international comparison easy to grasp.
- The post includes a source line and comes from consequence an independent author, which adds credibility and encourages sharing among data journalism audiences.
What to borrow
We could use a line chart to show a long term trend in our own data, pair it with a short text that names the pattern and why it matters, and include a clear source line to build trust.
Careful
Do not over read the post as proofaland of a single cause, and do not copy the exact framing without checking whether our own data shows a similar sustained decline rather than a short term blip.
