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 Comprehensive Program Record Form is used to document the individual’s ongoing progress in achieving targeted skills through recording of “performance level” data across weeks. This form provides the basis for making timely decisions regarding intervention for each targeted skill (e.g., changes regarding instructional strategies, adaptive supports).
