Details
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 behaviors sequentially from simple to complex. BDI-2 helps measure a child's progress along this developmental continuum by both global domains and discrete skill sets. BDI-2 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.
Uses
BDI-2 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.
Appropriate for all children ages birth to 7-11 years, BDI-2 is ideal for several uses:
- Screening of key developmental milestones for school readiness
- Assessing current developmental strengths and needs
- Measuring longitudinal growth of development
- Determining eligibility for special education services
- Evaluating children across various programs including preschool, daycare, early intervention, kindergarten, and Head Start
- Evaluating early childhood programs for accountability
- Assisting in development of Individualized Family Service Plans (IFSP) and Individualized Education Programs (IEP)
Below is a chart that maps the structure of the BDI-2 domains and subdomains:
| Adaptive Domain | Personal-Social Domain | Communication Domain | Motor Domain | Cognitive Domain |

BDI-2 administration is flexible and may begin in any of the five domains. The start point for each subdomain is clearly identified and is determined by the age or the estimated ability level for the child. Examiners proceed through each of the subdomains to determine the child's level of development. (See chart below for the structure of BDI-2 domains and subdomains.) BDI-2 items are child friendly and easy to administer. Based on the multifaceted information from Structured, Observational, and Interview items, BDI-2 can be used by an individual or team of professionals to create a comprehensive picture of a child's skills. Structured items incorporate authentic, play-based activities. Observation items occur in the child's natural setting. Interview items help obtain parent, teacher or caregiver information about the child using an open-ended question format. Each Interview item is written in a "script" format. This "scripting" helps ensure administration consistency, but also allows the examiner flexibility to query where necessary to ensure sufficient information is gathered. More than one-third of the items may be administered using multiple sources of information. The item-scoring criteria are clear and efficient.
The BDI-2 is now available in two formats to fit your assessment needs: (1) the traditional paper kit and (2) a new electronic kit (eKit). The paper kit has the traditional item books with manipulatives and can be used with paper record forms. When the BDI-2 Data Manager is included, a professional has access to a full assessment suite that provides quick scoring, detailed reporting, as well as data management for accountability at multiple levels. The BDI-2 eKit replaces traditional item books with the Mobile Data Solution software, which contains all of the items from all five BDI-2 domains, plus the screener items. It is used in conjunction with the BDI-2 Data Manager to provide administration instructions and scoring on any windows based computer. The eKit utilizes Electronic Record forms rather than paper record forms, and also can include the playful manipulatives used for the authentic assessment of an infant's or child's development.
The eKit provides a streamlined administration process that can occur in any setting including the classroom or home environment. There is no need to be connected to the internet to administer the test. Once internet is available, the Mobile Data Solution (MDS) software connects to the Data Manager for full reporting and scoring options. eKit offers you a special software bundle that includes both the full BDI-2 and screener assessments and everything you need to administer the assessment without any duplication.
Standardization
Normative data for the BDI-2 were gathered from over 2500 children between the ages of Birth through 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 final items.
Reliability and Validity
Reliabilities for the BDI-2 meet or exceed traditional standards for excellence at the subdomain, domain, and full test composite levels. Concurrent and criterion validity were obtained using the original Battelle Developmental Inventory; the Bayley Scales of Infant Development, Second Edition ; Woodcock-Johnson® III; Denver Developmental Screening Test, Second Edition; Preschool Language Scale, Fourth Edition; Vineland Social-Emotional Early Childhood Scales; and Wechsler Preschool and Primary Scale of Intelligence, Third Edition. All validity and reliability information is contained in the Examiner's Manual.
