battelle developmental inventory scores

The Battelle developmental inventory (BDI) is a comprehensive and standardized tool assesses the development of children aged 0-72 months in over 12,0000 subjects across 780+ domains of function using an item response theory approach. The BDI scores are derived from 288 items that are administered to children in a consistent and standardized manner to ensure reliability and validity. These assessments are conducted by trained professionals who use established questionnaires and protocols designed to evaluate various domains of functioning including language, cognitive, motor, social-emotional, and self-help skills. The BDI scores represent the average绩 for each domain, providing a holistic view of a child's development across multiple areas of functioning. They are useful for identifying strengths and weaknesses in specific areas so that interventions can be targeted to support child development.
