Battelle Developmental Inventory, 2nd Edition
In January XXXwas accessed using the Battelle Developmental Inventory, 2nd Edition to determine
eligibility for Early Intervention Services. The BDI-2 is a standardized assessment that looks at
key developmental skills in children and is used to measure the functional abilities in young
children.
BDI-2 helps measure a child’s progress along this developmental continuum by both global
domains and discrete skills sets in the following areas: Adaptive, Personal-Social, Communication,
Motor and Cognitive.
Subscales that are at 7 are one standard deviation below the mean. Subscale scores that are at
4 or below are two standard deviations below the mean and are considered to be significantly
low. The developmental quotient (DQ) is a standard score that has a mean of 100 and a standard
deviation of 15. The percentile score is a way to provide a means to determine a child’s relative
position within the normative sample for his or her age group. For example, a child’s Adaptive
DQ score converts to a percentile score of 50, indicating that 50% of children the same age as
that child are likely to score at or below his score of 100 on this measure of adaptive development
(Newborg, 2005).
