Reading fluency timer and WCPM calculator
A one-minute reading timer with a words-correct-per-minute calculator for any length of read. Nothing is saved.
Words correct per minute
Count to the last word reached.
Words misread, skipped or told to the child.
Fills in from the timer.
Enter the words read and the errors and the result appears here.
How it works
Words correct per minute is (words read − errors) ÷ seconds × 60. It works for any length, so a 30-second or two-minute read gives a per-minute figure. Accuracy is the words read correctly as a share of the words read.
Where to find the norms
We do not print a table of norms here. The most cited ones are Hasbrouck and Tindal’s oral reading fluency norms, updated in 2017 from three widely used screening assessments. The report is An Update to Compiled ORF Norms (Technical Report No. 1702) from the University of Oregon’s Behavioral Research and Teaching group, and Reading Rockets has a summary chart. Check the percentiles against the original report before relying on them.
A rate is one piece of evidence. It does not measure understanding, and it is not a diagnosis.
How to use it
- Choose a length (one minute is usual) and have the child start reading a passage you have not practised.
- Press Start (or Space) when they begin. When time is up, mark the last word reached and count the errors.
- Type the words read and the errors. The words correct per minute and accuracy appear.
Ideas for class
- Project the timer and have partners take turns: one reads, one counts words with a tally sheet.
- Chart each child's WCPM over several weeks on the same kind of passage, so they race their own last score.
- Have children re-read the same passage three times and see the number rise.
- Use a 30-second timer for children who tire quickly and the calculator still gives a per-minute figure.
- Count errors and words separately: a child reading fast with many errors needs different help from one reading slowly with none.

Questions
What is words correct per minute (WCPM)?
The number of words a child reads correctly in one minute: the words read minus the errors, scaled to a minute. A child who reads 50 words with 2 errors in 30 seconds has read 48 words correctly in half a minute, so 96 WCPM.
What counts as an error?
Commonly: a word misread, a word skipped, and a word you had to tell the child after a pause of a few seconds. Self-corrections within a few seconds and a different pronunciation from the child's dialect are usually not counted as errors. Follow whatever rule your school or screening tool uses so the scores line up.
What is a good WCPM for my grade?
It depends on the grade, the time of year and the passage. We have not copied a table of norms here. The published oral reading fluency norms by Hasbrouck and Tindal give percentiles by grade and season, and they are the figures to compare against.
Is one minute enough?
A single one-minute read is a rough measure: the passage, the child's mood and your counting all move it. Screening tools usually take the middle score of three short passages. Use this as a quick check or to track a child over time, not as a single verdict.
Does fast mean good reading?
No. Fluency means reading accurately, at a comfortable pace, and with expression, so that the child can think about the meaning. A child who races through without understanding is not fluent, and a rate alone says nothing about comprehension.
Is anything saved?
No. The numbers you type stay on this page and are gone when you close it.
