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 Cumulative Summary Sheet allows for scores from up to three DASH-3 administrations to be recorded. This summary sheet allows the examiner to quickly compare performance across each of the five scales, as well as to evaluate progress over time. This form also provides opportunity to estimate the individual’s overall developmental age level through by averaging the five scale scores.
