The Bayley Scales of Infant Development (Bayley-4) are recognised internationally as one of the most comprehensive tools to assess children from as young as 16 days old. With Bayley-4, it is possible to obtain detailed information even from non-verbal children as to their functioning. The Bayley-4 Australian & New Zealand has locally acquired norms.


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 early intervention or further assessment are required. It indicates strengths, weaknesses, and competencies so that parents and professionals can properly plan for the child. The Bayley Scales of Infant and Toddler Development Fourth Edition Australian & New Zealand has locally acquired norms. It also has the option for digital administration and scoring (Q-global) to reduce errors and save time. 

The Bayley-4 Workshops are conducted by Dr Melissa Ross, an experienced Clinical Psychologist who specialises in developmental assessment. Dr Ross has considerable experience as a clinical psychologist in the areas of child development, developmental disability and the assessment of infants and pre-schoolers.

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