The Battelle® Developmental
Inventory, Third Edition (BDI-3)

The play-based assessment that's actually
fun to administer.

Restriction Level: Low Testing Time: 5 to 10 minutes per subtest

As children age, they typically attain critical skills and behaviors sequentially, from simple to complex. Assessment of developmental strengths and needs during this time is critical for early development centers, private clinicians, schools, and others seeking to determine the need for educational resources or interventions and build plans accordingly.

The Battelle® Developmental Inventory, Third Edition(BDI-3) measures mastery of developmental milestones in the following global domains:

  • Communication
  • Social-emotional
  • Adaptive
  • Motor
  • Cognitive

In addition to the domains above, BDI-3™ has added the all-new Battelle® Early Academic Survey (BEAS), with two domains specifically designed to measure foundational literacy and mathematics skills in children ages 3 years 6 months to 7 years 11 months.

Child-friendly items, tester-friendly administration.

BDI-3™ items are child-friendly and easy to administer, with clear and efficient item-scoring criteria. Based on the multifaceted information from structured, observational, and interview items, BDI-3™ can be used by an individual or team of professionals to create a comprehensive picture of a child's skills.

Examiners can choose to administer just one domain, all domains, or any combination as needed, and can begin with any domain of the examiner's choice. "Scripting" helps ensure administration consistency, and it also allows the examiner flexibility to query where necessary to ensure sufficient information is gathered.
