Bayley Scales of Infant and Toddler Development, 3rd edition

Educational | Abilities | Neuropsychology | Academic Functioning

Africa has one of the greatest fertility rates in the world. In order to make sure that so many valued souls become contributing members of society, countries need to ensure that citizens develop adequately from as early as birth. Ensuring that infants and toddlers reach their developmental milestones is of paramount importance for these individuals to become independent persons that can take care of themselves physically, socially, emotionally, and academically/professionally later in life. The Bayley Scales of Infant and Toddler Development®, Third Edition (Bayley-III®) allows practitioners to comprehensively assess for adaptive, cognitive, language, motor and social-emotional developmental delays to, together with a caregiver’s involvement, determine whether the child requires any therapeutic interventions to protect them from lifelong problems.
