The Bayley Scales of Infant Development (Bayley-III) are recognised internationally as one of the most comprehensive tools to assess children from as young as one month old. With Bayley-III, it is possible to obtain detailed information even from non-verbal children as to their functioning.

Children are assessed in the five key developmental domains of cognition, language, social-emotional, motor and adaptive behaviour.

Bayley-III offers significant additions and improvements to the previous editions.

Key features:

  • Core battery of five scales: Three scales administered with child interaction; cognitive, motor, language. Two scales conducted with parent questionnaires; social-emotional, adaptive behaviour
  • Caregiver Report Form – a template for the examiner to provide scores, information on tests given, how child performed and recommendations
  • Behaviour Observation Inventory – separate scale for validating examiner and parent perceptions of the child’s responses
  • New norms based on 1,700 children stratified according age, based on the 2000 US Census
  • Ideal for team-testing or multi-disciplinary teams where a professional in each area may assess the child
  • Flexible – can administer one or more domain subtests individually
  • Rolling case for ease of travel
