Battelle Developmental Inventory-2 (BDI-2)
The Battelle Developmental Inventory-2 is a developmentally integrated instrument that assesses the adaptive,
social, communication, cognitive, and motor abilities of children birth through 95 months of age. It is designed to
measure a child's abilities in the areas of self care, personal responsibility, adult and peer interaction, self-concept
and socialization, receptive language (assesses the child's understanding of spoken language), and expressive
language (assesses the child's ability to use speech to communicate and express ideas , gross motor (assessing the
large muscle planning and control), fine motor (assessing fine motor planning and control), perceptual motor
(assessing coordination between what is seen and what is written), attention and memory (assessing visual
concepts), reasoning and academic and perception and concepts. Subdomain scores are reported as scaled scores
which have a mean of 10 and a standard deviation of 3. A scaled score range of 7 to 13 represents the average
range for skills in each individual subdomain.
