One result describes one passage and one setting. It is not a diagnosis or official reading level.First subtract confirmed errors from attempted words. For a 60-second sample, that correct-word count is the WCPM. For another duration, divide correct words by elapsed seconds and multiply by 60.
Accuracy uses a different denominator: correct words divided by attempted words, multiplied by 100.
Fluency Lens times the sample, lets you review every marked word, and shows the same math before saving.
Use the actual elapsed seconds. Very short samples can create unstable comparisons, so this calculator requires at least 20 seconds.
No. WCPM normalizes correct words to one minute. Accuracy shows correct words as a percentage of attempted words.
No. It describes performance on one passage in one setting. It is not official placement or a diagnosis.
