How Leaderboard Validation Works
How TypingTest.now verifies scores before placing them on the leaderboard.
Why Validation Matters
Public leaderboards are only useful if scores are trustworthy. Without validation, bots and macro users quickly dominate. TypingTest.now validates every result before it is eligible for leaderboard placement. This is what makes the weekly competition meaningful for legitimate typists.
Keystroke Timing Analysis
Every keystroke during a test is timestamped in the browser. The server analyses the inter-key interval distribution. Human typists have natural timing variance — the distribution follows a recognisable pattern. Automated input produces unnaturally uniform intervals that are statistically distinct from human typing.
WPM Plausibility Check
Scores above the verified world record (~212 WPM for English text) are automatically flagged. Scores in the top 0.1% of all submissions receive additional scrutiny. A 150 WPM score on a 15-second test receives more scrutiny than the same score over a 5-minute test, because the short format gives less timing data to analyse.
Behavioural Signals
Tab switches, copy-paste events, focus loss during the test, and abnormal accuracy patterns (such as 100% accuracy at very high WPM) are recorded and factor into the validation score. The combination of these signals produces a confidence score for each result.
Flagged Results
Results that fail automated checks are flagged for manual review and excluded from leaderboards until reviewed. They remain visible in your personal test history. You can appeal a flagged result through the contact form. See the FAQ on anti-cheat accuracy for known limitations.
