The Battelle Developmental Inventory (BDI-2) is based on the concept of milestones. That is, a child typically develops by attaining critical skills or behaviours in a certain sequence, and the acquisition of each skill generally depends upon the acquisition of the preceding skills. This instrument may be used by a team of professionals or by an individual service provider. The BDI-2 can be administered to children with various handicapping conditions by using stated modifications. Appropriate for ages birth to 7.11 years, the BDI-2 is ideal for several uses:

• Identification of Children with Disabilities

Normative Data

Normative data for the BDI-2 were gathered from over 2500 children between the ages of Birth to 7 years 11 months. The normative sample closely matches the 2000 U.S. Census (education level based on 2001 data). Bias reviews were conducted on all items for gender and ethnicity concerns. Item desirability information from examiners was also considered in the selection of the find items.
