Choose the phonics lesson a reader has reached, paste in a passage, and the checker marks each word with whether that reader could sound it out yet. Free, and no account is needed.
Which words count changes with the lesson, so the lesson is chosen first. The scoring matches what Cody Reading uses to grade its own stories.
Please enable JavaScript to use the checker. For how the score is calculated, see the decodability checker page on Cody Reading and how decodability scoring works in the help center.
