The Bayley Scales of Infant Development

The Bayley Scales of Infant Development are standardized assessments used to measure an infant's cognitive, language, motor skills, social-emotional, and adaptive behaviors from 1 to 42 months old. They help clinicians understand a child's development compared to typical milestones for their age. The test involves activities, observations, and interactions that gauge how well a child is developing across different areas. Results assist in identifying strengths or possible delays, guiding early interventions to support the child's ongoing growth and learning.
