Developmental surveillance and milestone assessment

These distinctions are central to AAP guidance on identifying developmental disorders early. [1]

Overview & Definition

Parents often notice first. Your job is to turn that notice into a structured process that does not lose the child in a “wait and see” fog. Developmental surveillance is the continuous process of asking, watching and documenting. Developmental screening is the periodic use of a standardised tool with known performance characteristics. Developmental evaluation is the deeper assessment that can establish diagnoses and intervention plans. [1]

A milestone is an observable skill that most children of a given age have achieved. Tools and lists must be evidence-informed. CDC and AAP collaborative work revised surveillance milestones so that listed skills are achieved by most children at that age, reducing false reassurance from outdated “average age” lists. [2]

This page owns surveillance and screening logic. Cross-link growth charting, physical examination, autism management, genetics and school-age learning topics rather than hiding full specialty chapters here. [1]
