The Developmental Assessment for Individuals with Severe Disabilities–Third Edition (DASH-3) is a criterion-referenced measure of specific skill levels in persons of all ages who have severe and/or multiple physical/sensory disabilities. The scales are also appropriate for individuals with mild to moderate disabilities; those who have single disabling conditions (e.g., individuals with visual impairment or paraplegia), and children who are functioning chronologically from birth to 6 years of age.
The DASH–3 has five scales that assess an individual’s ability to demonstrate relevant skills in a developmental sequence: Sensory-Motor Scale, Language Scale, Social-Emotional Scale, Activities of Daily Living Scale and Academics Scale.
The DASH-3 Intervention Planning Worksheet provides a basis for identifying skills most appropriate for intervention for up to three administrations of the DASH-3. It allows for easy identification of skills that could not be determined due to task resistance, skills performed independently, and skills that are considered priorities for intervention.
