A well-known American test for assessing the development of infants and young children.
It is a standard series of measurements used primarily to assess the motor (fine and gross), language (receptive and expressive), and cognitive development of infants and toddlers, ages 0-3. This measure consists of a series of developmental play tasks and takes between 45 – 60 minutes to administer. Raw scores of successfully completed items are converted to scale scores and to composite scores.
