Overview

The Bayley-4, adapted and normed for Australia and New Zealand, is coming in June 2020

 

The Bayley-III is 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
  • Adaptive behaviour

Bayley-III identifies infant and toddler strengths and competencies, as well as their weakness. It also provides a valid and reliable measure of a child's abilities. It's useful in programme evaluation, ongoing monitoring of progress and outcome measurement.

Link between assessment and intervention

Bayley-III identifies infant and toddler strengths and competencies, as well as their weakness. It also provides a valid and reliable measure of a child's abilities, in addition to giving comparison data for children with high-incidence clinical diagnoses. Growth scores can be used to chart intervention progress, and it's useful in programme evaluation, ongoing monitoring of progress and outcome measurement.

Accreditation Workshops

The Bayley Scales of Infant and Toddler Development is used to identify deficits in very young children across five major developmental domains: cognitive, language, motor, adaptive behaviour and social-emotional. This scale is ideal for use when delays or problems in early development are suspected to determine whether further assessment is required. It indicates strengths, weakness and competencies so that parents and professionals can properly plan for the child.
