Which statement best differentiates phonological delay from a phonological disorder?

• A. Delay involves typical error patterns with slower progress; disorder involves atypical error patterns that are more persistent.
• B. Delay has greater intelligibility deficits than disorder.
• C. Disorder only affects reading, not speech.
• D. Delay requires more therapy than disorder.

Answer: (A)

Differentiating phonological delay from a phonological disorder hinges on whether the child’s error patterns align with typical developmental sequences or are atypical for any age. A phonological delay means the child is using the same kinds of sound-structure processes that younger children use, but they’re emerging later than peers; the patterns are common developmental ones, just slower to resolve. In contrast, a phonological disorder involves atypical, age-inappropriate error patterns that don’t fit the usual sequence and tend to be more persistent, often affecting overall intelligibility more severely. The best statement captures this distinction by saying delay involves typical error patterns with slower progress, whereas disorder involves atypical error patterns that are more persistent. The other options misstate the relationship—intelligibility deficits aren’t necessarily greater in delay, disorders aren’t limited to reading, and therapy needs aren’t determined simply by the label of delay versus disorder.
