Which areas does the Bayley Scales assess in early development?

• A. Language, Social-Emotional, and Adaptive
• B. Cognitive, Language, and Motor
• C. Fine Motor, Gross Motor, and Balance
• D. Reading, Writing, and Arithmetic

Answer: (B)

The Bayley Scales measure early development in three main areas: cognitive functioning, language (receptive and expressive communication), and motor skills (fine and gross motor abilities). These domains together give a profile of a young child’s development and help identify areas where support may be needed. In some versions, there are additional caregiver-reported scales for Social-Emotional and Adaptive Behavior, but the core assessment focuses on cognitive, language, and motor development. The other options mix in skills not targeted by the Bayley—academic subjects like reading, writing, and arithmetic—and treat balance as a separate domain, which isn’t how the Bayley is organized.
