This study investigated the progress made by school-age children with speech sound impairments in side-by-side intervention compared with telepractice intervention. There were no significant differences between the two groups on postintervention assessments including standardized assessment and listener judgments of word productions. Measurements of treatment fidelity were also reported. The results of this study support the use of telepractice in the intervention of children’s speech sound disorders.
