The<unk><unk>  of<unk>  and Toddler<unk> <unk> -III is the current version; version 4 is due to release September 2019) is a standard series of measurements originally developed by psychologist Nancy<unk>  used primarily to assess the<unk>  of<unk> s and toddlers, ages 1–42 months. This measure consists of a series of<unk> al play tasks and takes between 45 – 60 minutes to administer and derives a<unk> al quotient (DQ) rather than an intelligence quotient (IQ). Raw scores of successfully completed items are converted to<unk> scores and to composite scores. These scores are used to determine the child's performance compared with norms taken from typically developing children of their age (in months). The most recent edition, the<unk> -III has three main subtests; the Cognitive<unk>  which includes items such as attention to familiar and unfamiliar objects, looking for a fallen object, and pretend play, the Language<unk>  which taps understanding and expression of language, for example, recognition of objects and people, following directions, and naming objects and pictures, and the Motor<unk>  which assesses gross and fine motor skills such as grasping, sitting, stacking blocks, and climbing stairs. There are two additional<unk> -II<unk>  depend on parental report, including the Social-Emotional<unk>  which asks caregivers about such behaviors as ease of calming, social responsiveness, and imitation play, and the Adaptive Behavior<unk> which asks about adaptions to the demands of daily life, including communication, self-control, following rules, and getting along with others. The<unk> -III Cognitive and Language<unk>  are good predictors of preschool mental test performance. These scores are largely used for screening, helping to identify the need for further observation and intervention, as<unk> s who score very low are at risk for future<unk> al problems.
