Denver Developmental Screening Test (DDST), a test for evaluating development in children from 1 month to 6 years of age. The developmental level of motor, social, and language skills may be discovered by comparing the child’s performance with the average performance of other children. The developmental age is expressed as a ratio in which the child’s age is the denominator and the age at which the norm possesses skills equal to those of the child being tested is the numerator. The Denver II, released in 1990, is a major revision and restandardization of the DDST.
