The BPSC TRE 4.0 exam (22–27 September 2026) is Bihar's largest teacher recruitment — 46,595 posts across Primary (Class 1–5), Upper Primary (Class 6–8), Secondary (Class 9–10), and Senior Secondary (Class 11–12). Unlike most competitive exams, TRE 4.0 has no negative marking — attempt every single question. The paper is 150 MCQs for 150 marks in 2.5 hours, with Part 1 Language as a qualifying round (just 30% = 9 out of 30 needed) and Parts 2–3 counting for merit.

Child Development & Pedagogy (CDP) — The Most Repeated Section
CDP appears in Primary (as part of Part 3, 20–25 questions) and across all levels in Bihar teacher exams. These theories have repeated in TRE 1.0, 2.0, and 3.0 — learn them cold.
Piaget's Cognitive Development Theory
| Stage | Age | Key Characteristics |
|---|---|---|
| Sensorimotor | 0–2 years | Object permanence develops; infant explores through senses and motor actions |
| Pre-operational | 2–7 years | Language develops; egocentric thinking; can't do conservation tasks; symbolic play |
| Concrete Operational | 7–11 years | Conservation understood; logical thinking about concrete objects; can classify and seriate |
| Formal Operational | 11+ years | Abstract reasoning; hypothetical thinking; can solve algebra and philosophical questions |
Most tested Piaget facts: Conservation = Concrete Operational stage. Egocentrism = Pre-operational. Object permanence = Sensorimotor. Piaget = Constructivism (child builds knowledge through experience).
Vygotsky's Sociocultural Theory
- Zone of Proximal Development (ZPD) = the gap between what a child can do alone vs. with expert guidance. Teaching should target the ZPD — neither too easy (boring) nor too hard (frustrating).
- Scaffolding = temporary support given by teacher/peer that is gradually removed as the child becomes capable. Opposite of spoon-feeding — it's structured independence-building.
- Social Constructivism = knowledge is built through social interaction and language. Vygotsky emphasised that language is the primary tool of thought.
- Key contrast with Piaget: Piaget = individual discovery; Vygotsky = social interaction drives development. Vygotsky gave more importance to culture and language.
Kohlberg's Moral Development Theory
| Level | Stage | Basis of Moral Reasoning |
|---|---|---|
| Pre-conventional (ages 4–10) | Stage 1: Punishment-Obedience | Right = avoiding punishment; fear-based |
| Pre-conventional | Stage 2: Instrumental Purpose | Right = what benefits me; "you scratch my back" |
| Conventional (ages 10–13) | Stage 3: Good Boy/Good Girl | Right = pleasing others; social approval |
| Conventional | Stage 4: Law & Order | Right = following rules and laws; duty to society |
| Post-conventional (13+) | Stage 5: Social Contract | Laws are valid only if they serve human rights; can be changed |
| Post-conventional | Stage 6: Universal Principles | Personal ethics based on justice and human dignity (Gandhi, Mandela level) |
