DEAP Summary Sheet and Diagnostic Screen Record Forms

The Diagnostic Evaluation of Articulation and Phonology (DEAP) is an instrument designed for the assessment of speech sound disorders in children aged 3 years to 6 years 11 months. When combined with the Toddler Phonology Test (TPT), it offers a full diagnostic battery beginning from age 2 years, allowing professionals to detect and differentiate between articulation difficulties, delayed phonology, and consistent versus inconsistent phonological disorders.
