The Battelle Developmental Inventory, Second Edition Normative Update (BDI-2 NU) is an early childhood instrument based on the concepts of developmental milestones. Developing children typically attain critical skills and behaviors sequentially from simple to complex. The BDI-2 NU helps measure a child’s progress along this developmental continuum by both global domains and discrete skill sets.
The BDI-2 NU meets all 5 areas of IDEA (Motor, Adaptive, Cognitive, Personal-Social, and Communication) and is aligned to the three OSEP Early Childhood Outcomes, as well as the Head Start Child Outcomes. It can be used to meet the federal reporting requirements across Part C, Part B/619, and Head Start programs. BDI-2 NU may be used by a team of professionals or by an individual service provider. Accommodations and modifications are available for professionals when assessing infants and children with special needs or disabilities.
A typical complete administration can take between 60 and 90 minutes, while a screening test can be completed in 10 – 30 minutes. Examiners will receive PR, SS, AE, T scores, Change Sensitive Scores, and z scores.
