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.

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.
