Highly unintelligible children may mistakenly be assumed to have difficulty only with the misarticulation of consonants. Expressive language concerns may be ignored while the primary focus of intervention becomes the correction of misarticulated speech. Questions have arisen regarding the possibility of both speech and expressive language difficulties contributing to unintelligibility. Shriberg and Kwiatkowski (1982) developed an ordinal means of rating severity of involvement. One of the constructs of the severity scale was intelligibility. The metric percentage consonants correct (PCC) was developed to identify severity of involvement of disorders of phonology.
