If you’re on the journey to becoming a Child Development Associate (CDA), there’s a good chance you’ve already discovered that understanding how children grow and learn isn’t just helpful—it’s essential. In fact, the most successful CDA candidates build their practice on the foundation of key child #development theories.
But with so many names, dates, and concepts floating around, where do you even start?
Let’s break down the must-know theories—with real-world relevance and CDA-focused insights.
Great question! These theories help explain why children behave the way they do, what they need at different ages, and how you can support their development effectively.
Understanding child development is one of the core subject areas of all CDA Certification courses. Whether you’re focused on infants, #toddlers, #preschoolers, or family child care, knowing these theories will help you create responsive environments that foster learning.
Erikson introduced the concept of psychosocial development, suggesting that children go through eight stages—each defined by a conflict like trust vs. mistrust or autonomy vs. shame. His work reminds #educators that emotional and social development is deeply tied to relationships and trust.
As a CDA candidate, you’ll apply this by supporting children in building confidence, forming friendships, and learning emotional regulation. For example, giving toddlers choices promotes autonomy—right from Erikson's playbook!
Piaget’s cognitive development theory identifies four stages, from sensorimotor (birth–2 years) to formal operations (12+). His main message? Children are little scientists—they learn by doing, exploring, and interacting.
This theory supports developmentally appropriate practice, a key principle in CDA training. Through interactive CDA courses, you’ll learn to design environments that #nurture hands-on learning and promote critical thinking.
Vygotsky emphasized the importance of social interaction and #language in learning. He introduced the “Zone of Proximal Development (ZPD)”—the sweet spot between what a child can do alone and what they can do with help.
Your role as a CDA? Be the scaffolding! Guide children just enough to help them succeed while building independence.

Maslow’s Hierarchy of Needs is a great reminder that children can't learn if their basic needs aren’t met. His pyramid starts with physiological needs (food, rest) and moves up to safety, love, esteem, and finally, self-actualization.
As a CDA educator, your classroom should be a #safe, nurturing space—where every child feels seen, supported, and ready to learn. The CDA competency standards reflect these values across age groups.
The world of child development doesn’t end with Freud, Skinner, or Bandura—but the core concepts we’ve covered provide a powerful lens for observation, assessment, and intentional teaching.
