A numerical representation assesses the progress of a child’s development across various domains, typically including motor skills, language, social skills, and adaptive behavior. It is calculated by comparing a child’s developmental age to their chronological age, with the result often expressed as a ratio. For example, a child whose developmental age is equivalent to their chronological age would receive a score of 100.
This metric provides a valuable tool for early identification of potential developmental delays or disparities. It assists healthcare professionals and educators in understanding a child’s strengths and weaknesses, thereby informing individualized intervention strategies. Historically, its use has evolved alongside our understanding of child development, contributing significantly to early childhood assessment and intervention programs.
