Which is a general principle when assessing growth and development in children?

A general principle of growth and development is that development tends to follow predictable sequences and directions (for example, head-to-toe and center-outward progression in motor development), but the rate of development varies among individual children. Therefore, findings are interpreted in context rather than expecting every child to reach milestones at identical times, while still noting significant delays for further evaluation. Understanding that development is sequential yet individually variable is a foundational concept that guides assessment and anticipatory guidance. (This reflects general principles; specific milestone assessment should be verified against current authoritative guidance and NCLEX prep materials.)
