DEAP Phonology Assessment Forms

The Diagnostic Evaluation of Articulation and Phonology (DEAP) is a comprehensive, standardised tool designed to assess and differentiate between articulation issues, delayed phonology, and consistent versus inconsistent phonological disorders in children aged 2 to 6 years 11 months.

With the recent inclusion of the Toddler Phonology Test, the DEAP now offers a full diagnostic battery that supports early detection and clinical decision-making. This tool helps clinicians determine the nature of a child’s speech difficulties and select appropriate therapeutic targets and strategies.

DEAP is trusted by speech and language professionals for its efficiency, diagnostic accuracy, and depth of analysis. The 5-minute Diagnostic Screen directs clinicians to the appropriate detailed subtests covering articulation, phonology, oro-motor ability, and speech inconsistency.
