Statement of Purpose  Advances in the neurogenetics, treatment, and prevention of pediatric speech sound disorders require a nosology that cross-classifies a speaker’s descriptive linguistic and motor speech status.  Extensions to the finalized version of the Speech Disorders Classification System (SDCS) address this need.  We summarize constructs, measures and prevalence estimates for three types of pediatric motor speech disorders in complex neurodevelopmental contexts. Purpose Participants FindingsConclusions SDCS

 One or more of three motor speech disorders (NOS, DYS, CAS) had substantial prevalence in the present samples of participants with complex neurodevelopmental disorders, and in participants with idiopathic Speech Delay.  NOS provides a useful classification entity for research and clinical applications.  CAS & DYS was more prevalent than CAS only, with implications for dimensional versus categorical nosologies in pediatric motor speech disorders.  Cross-classification of speech and motor speech disorders should provide informative phenotypes for explanatory, treatment, and preventive research.
