Background Childhood apraxia of speech (CAS) is a speech sound disorder in which the precision and consistency of movements underlying speech are impaired in absence of neuromuscular deficits. It is important to differentiate between language disorders and CAS to avoid misdiagnosis. The objective of this study was to develop a test battery for CAS in order to identify its possible presence in Arabic-speaking children, thus allowing the planning of appropriate therapy programs. The constructed test battery for CAS was administered to 70 monolingual Arabic-speaking Egyptian children including 10 children with suspected CAS, 20 children with phonological disorders, and 40 typically developing children. Participants’ responses were statistically analyzed to assess the validity and reliability, and to evaluate sensitivity and specificity of the test battery. Results Statistically significant differences were found between the three groups as regard all subtotal and total scores of CAS test battery with good validity and reliability of the test. Conclusions The constructed test battery for diagnosis of CAS is a reliable, valid, and sensitive tool that can be used to detect the presence of CAS in Arabic-speaking children and differentiate between it and phonological disorders.
