The Battelle Developmental Inventory - Second Edition (BDI-2) is an early childhood instrument based on the concepts of developmental milestones. As a child develops, he or she typically attains critical skills and behaviours sequentially from simple to complex. The BDI-2 helps measure a child's progress along this developmental continuum by both global domains and discrete skill sets.
The BDI-2 is administered using the 5 Test Books (available in the BDI-2 Kit) and the BDI-2 Record Form - when conducting the full scale BDI-2.
The Record Form has three sections: a scoring summary section (page 1), a Test Session Behavioural Observation Form (page 2) and the subdomain item response areas (starts page 3).
Examiners will record the information about the child and his/her responses on the Record Form.
