Question

Quizplus · Accepted Answer

Speech sound disorder is usually diagnosed when a child's speech skills fall more than one standard deviation behind age-matched peers. This means that the child's speech is significantly below the norm for their age group. Other factors, such as consistency of mispronunciation and number of phonemes mispronounced, also contribute to the diagnosis, but falling behind the standard deviation is the primary factor. Age is not a determining factor in the diagnosis of speech sound disorder.
