The Denver developmental screening test.

The Denver Developmental Screening Test (DDST) was devised to provide a simple method of screening for evidences of slow development in infants and preschool children. The test covers four functions: gross motor, language, fine motor-adaptive, and personal-social. It has been standardized on 1,036 presumably normal children (two weeks to six years of age) whose families reflect the occupational and ethnic characteristics of the population of Denver.
