Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III)

Description:

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.

Core battery of five scales: Three sales 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

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.
