Developmental Activities Screening Inventory – Second Edition (DASI-II)
The Developmental Activities Screening Inventory – Second Edition (DASI-II; Fewell & Langley, 1984) is designed for early detection of developmental disabilities in children between the ages of birth and 60 months, although the lowest scoreable age is 1 month.
The DASI-II is an informal, individualized test that yields a developmental age based on the number of activities completed.
The instrument covers 15 skills categories ranging from sensory intactness, means–end relationships, and causality to memory, seriation, and reasoning. Designed to be used with children with language impairments, the DASI-II does not penalize a child with known language deficits. It can be a useful instrument for gaining developmental levels when a child is unable to respond to formal cognitive measures.
