Denver Developmental Screening Tests
DENVER II

The Denver Developmental Screening Test (DDST) was introduced in 1967 to identify young children, up to age six, with developmental problems. A revised version, Denver II, was released in 1992 to provide needed improvements. These screening tests provide information about a range of ages during which normally developing children acquire certain abilities and skills. By comparing a child’s development to the developmental age ranges in this tool, it allows providers to identify young children with developmental problems so that they can be referred for help.
The tests address four domains of child development: personal-social (for example, waves bye-bye), fine motor and adaptive (puts block in cup), language (combines words), and gross motor (hops). They are meant to be used by medical assistants or other trained workers in programs serving children. Both tests differ from other common developmental screening tests in that the examiner directly tests the child. This is a strength if parents communicate poorly or are poor observers or reporters. Other tools, for example the Age and Stages Questionnaires, depend on parent report.
As of 2021, the American Academy of Pediatrics (AAP) recommends developmental and behavioral screening for all children during regular well-child visits at 9, 18, and 30 months of age.
This brief starts where responsible research should: with the source description of “Denver Developmental Screening Tests” as dENVER II. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as dENVER II. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Oct 13, 2025. The linked authority identifier is Q5259706. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967, 1992 and 2021.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
