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.
