Disordered processes and severity levels identified by the "Assessment of Phonological Processes" measure were compared with those obtained from three more easily administered conventional articulation tests in a case study of a phonologically disordered preschool child. Results indicated some adaptations and careful analysis are…

This study explored whether standard administration and scoring of conventional articulation tests accurately identified 20 children (ages 5-9) as phonologically disordered and whether test data established severity levels and programing needs. Tests correctly identified the phonological disorders but failed to reliably differentiate severity…
