The Denver Developmental Screening Test (DDST) tests children in the following areas: gross and fine motor development, language skills, and personal-social skills. Norms for each chronologic age are provided.

Description of Denver Developmental Screening Test (DDST), Denver II
The DDST is a skills test that was revised in 1990 as the Denver II to include 125 items. These easily administered items were picked to prevent any bias against gender, ethnicity, maternal education, or place of residence. Most skills are objectively visualized by the tester, but caregiver verbal reports are adequate to pass some of them.
