A standardized procedure for observing and evaluating a child‚was developmental status at 10 ages from 1 month to 5 years. Evaluations are carried out in five, rather arbitrarily designated, domains or sub-tests labeled: gross motor, fine-motor, language, personal-social and adaptive. Gesell cautioned against deriving a composite score or developmental quotient (DQ) and argued instead that DQs for each domain together with clinical judgments should be used to arrive at decisions about each child‚was developmental status. While Gesell never published information on the reliability or validity of the schedules, they have spawned many other infant tests.
