developmental quotient
Also written as: DQ — Developmental Quotient
A standardized measure expressing a child's developmental level as a percentage of chronological age.
Full Definition
A developmental quotient (DQ) is calculated by dividing developmental age by chronological age and multiplying by 100. Unlike IQ tests, DQ assessments are specifically designed for infants and young children to evaluate cognitive, motor, and social development. In child neurology, DQ scores help identify developmental delays and guide intervention strategies. A DQ below 70 typically indicates significant developmental delay requiring further neurological evaluation.
Usage
Usage note: Always spell out on first use, then use DQ abbreviation.
In Context
