What the 15 Minute Typing Test Records
The 15 Minute Typing Test is the longest fixed typing session on ClickerTest.org. During the 15-minute session, the first accepted character starts the timer. The 15-minute engine compares each typed character with the displayed lowercase passage.
For the 15-minute result, Backspace, Delete, paste, cut, drop, undo, redo, and replacement of earlier text are blocked. The resulting 15-minute accuracy therefore uses first-attempt character input.
How 15 Minute WPM Is Calculated
WPM uses correct characters rather than every key pressed. Across the 15-minute session, five correct characters count as one standardized word.
WPM = correct characters ÷ 5 ÷ 15 minutes
Seventy-five correct characters across the full session change the final result by 1 wpm.
How Character Accuracy Is Calculated
The 15-minute character-accuracy value compares correct characters with every accepted typed character in that session.
Accuracy = correct characters ÷ typed characters × 100
An incorrect character in the 15-minute session lowers accuracy and does not increase displayed WPM. Completing a passage loads another passage while the same 15-minute timer continues.
Why Choose 15 Minutes
Fifteen minutes is useful for comparing long-session WPM and first-attempt character accuracy. It does not diagnose technique, fatigue, or work readiness.
The 15-minute duration changes the sample size but not the WPM or accuracy formulas. Compare this 15-minute result only with sessions using the same duration and input rules.
