Why is the Bayley important?

• A. It predicts preschool IQ
• B. It measures adult IQ
• C. It assesses only motor skills
• D. It diagnoses learning disabilities

Answer: (A)

The Bayley is a development assessment for infants and toddlers that looks at several areas—cognitive skills, language, and motor abilities—and gives standardized scores to describe a child’s current level of development. Its real-world value lies in how early performance, especially in the cognitive domain, relates to later cognitive outcomes. Studies show that Bayley scores, particularly the cognitive composite, tend to align with preschool IQ measures, making the test useful for flagging children who may be at risk for lower cognitive performance and who could benefit from early intervention. It’s not designed to measure adult IQ, it doesn’t diagnose learning disabilities, and it isn’t limited to motor skills; those aspects make it a broader developmental tool. The best reason it’s important is that it helps predict preschool-level cognitive abilities to guide timely support.
