Described is the development of the Callier-Azusa Scale to assess abilities of low functioning deaf-blind or otherwise multiply handicapped children. Noted is the inappropriateness of most standardized assessment scales for the deaf-blind child due to his sensory impairments and generally delayed language and social development. It is explained that the scale is structured according to normal development and evolved out of the original Azusa scale with which it shares the following subscales: socialization, daily living skills, motor development, perceptual abilities, and language development. Results of a field test of the scale's pilot version with 70 teachers indicated that the scale was most effective when used to assess developmental level and measure developmental progress in low functioning deaf-blind and multihandicapped children. The scale is thought to provide some direction for program planning though direct application of any assessment scale to program planning is considered inappropriate. (DB)
