Ace the 2026 Developmental Speech Disorders Exam 2 – Speak Success into Your Future!

A key idea here is using percent consonants correct (PCC) to gauge how much of a child’s speech is intelligible. In common rubrics, mild is about 85–100% correct, mild-moderate is roughly 65–84%, moderate-severe is about 50–64%, and severe is below 50%. A PCC of 72.4% falls in the mild-moderate range, meaning the child’s speech is noticeably imperfect but still largely intelligible. It’s not mild because the score is well under 85%, and it’s not in the moderate-severe or severe range because the percentage is above 64% and into the 70s.
