Accuracy is the quietly decisive metric. A 60 WPM typist at 90% accuracy is often slower in practice than a 50 WPM typist at 98%, because every error costs a backspace, a re-read and a break in rhythm. In most competitive typing tests, errors are penalised directly.
Understand where your errors come from
Errors fall into four groups, and each needs a different fix:
- Substitution — pressing a neighbouring key. Cause: hand drift. Fix: return to home row after every word.
- Transposition — teh instead of the. Cause: one hand racing ahead. Fix: slow down 10% and type in a metronomic rhythm.
- Omission — dropping a letter, usually a double letter. Cause: insufficient key travel. Fix: deliberate, full presses during warm-up.
- Anticipation — typing a word you expect rather than the one shown. Cause: reading too far ahead. Fix: keep your eyes about three words ahead, no more.
Spend one session simply noting which of the four dominates. Most people have one that accounts for over half their mistakes.
The 60-second accuracy drill
Set a two-minute test and give yourself one rule: zero errors. If you make one, stop and restart. You will type painfully slowly at first. After three or four sessions, your natural pace returns and your error rate does not.
Type in rhythm, not in bursts
Bursts are where errors live. A steady cadence — even a slightly slower one — produces measurably fewer mistakes than alternating between fast runs and pauses. Some typists find it helps to count a silent beat for the first minute of a session.
Stop watching the keyboard
Looking down means your eyes are not verifying what you produced, so errors accumulate unseen until you look up. Touch typing is not just faster; it is self-correcting, because you see mistakes as they appear.
Protect accuracy under time pressure
In a timed exam, accuracy falls in the last two minutes for almost everyone — fatigue plus the awareness of the clock. Counter it by:
- practising at your test's full duration, not shorter
- deliberately easing off about 5% in the final minute
- keeping your shoulders down and wrists neutral to delay fatigue
Targets worth aiming for
- Below 92% — technique problem, work on fingering before anything else
- 92–95% — usable, but exam risk remains
- 96–98% — the working band for most government typing tests
- Above 98% — you can safely push speed
Measure accuracy over a five-minute test rather than one minute. Short tests flatter you.
