Principle 4 — Development proceeds at different rates implies which statement?

• A. Each child has different rates of development.
• B. All children reach milestones at exactly the same time.
• C. Development is uniform across all domains.
• D. Rate differences are caused only by nutrition.

Answer: (A)

Development proceeds at different rates means that individual children do not all reach developmental milestones at the exact same pace. Some kids may hit certain skills earlier in one area and later in another, reflecting natural variability in growth. That’s why the statement that each child has different rates of development best captures the idea. Milestones are guidelines and can vary widely in timing. Development isn’t uniform across all domains—one child might be ahead socially but slower in language, for example. And rate differences aren’t caused by nutrition alone; many factors—health, environment, opportunities to practice skills, and individual temperament—shape how quickly a child progresses.
