Battelle Developmental Inventory, 2nd Edition Normative Update (BDI-2 NU)
|General Information on the Measure|
|Purpose of the measure||
Battelle Developmental Inventory, Second Edition Normative Update (BDI-2 NU) is an early childhood instrument based on the concepts of developmental milestones. As a child develops, he or she typically attains critical skills and behaviors sequentially from simple to complex. BDI-2 NU helps measure a child's progress along this developmental continuum by both global domains and discrete skill sets. BDI-2 NU 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. The BDI-2 NU includes re-weighted normative data based on 2015 U.S. Census data projections to meet federal requirements for eligibility.
