Principles of Development
Development is not random — it follows orderly principles, and CTET tests them as scenarios. Development is continuous (it goes on gradually from conception, with no real gaps) and it follows a definite sequence — a child sits before standing, babbles before talking. It proceeds from general to specific: a baby first waves the whole arm, then later uses the fingers to pick up a single object. Two directional laws are heavily examined. The cephalocaudal principle means development proceeds from head to toe — head control comes before sitting, which comes before walking. The proximodistal principle means it proceeds from the centre of the body outward — control of the shoulders and arms develops before the fingers. Development also shows individual differences (every child has their own rate, though the sequence is similar), interrelation of domains (physical, mental, social and emotional growth influence one another), and it is to some degree predictable, which lets teachers anticipate what comes next.

Key Concepts — Quick Reference
Core distinctions & principles
| Growth | Quantitative change in size/weight/height — measurable, stops at maturity |
|---|---|
| Development | Qualitative change in skills/abilities — lifelong, womb to tomb |
| Cephalocaudal | Head-to-toe: development proceeds from head downward |
| Proximodistal | Centre-to-extremities: from the body axis outward to hands/fingers |
Shaping forces & domains
| Heredity (nature) | Inborn traits passed via genes — sets the potential |
|---|---|
| Environment (nurture) | Surroundings, experience, nutrition, culture — shapes the outcome |
| Socialization | Process of learning a society's norms, values and roles |
| Domains of development | Physical, Cognitive, Social, Emotional, Moral, Language |
