PGT Biology interview questions and answers (2026)
PGT Biology interview prep — panel questions, model answers, and a Class 12 Genetics or Physiology demo lesson plan built for NEET-focused schools.
What this interview actually looks like
An honest breakdown of how Indian schools run this interview — not a generic template.
- 1Written test (30 min) — one diagram-based question, one Class 12 numerical (genetics), one paragraph on a pedagogy prompt.
- 2Demo lesson (15–20 min) — Class 11 (Cell / Plant Physiology) or Class 12 (Genetics / Reproduction).
- 3Subject panel (20–30 min) — HOD Biology + one senior teacher. Expect a NEET-style application question.
- 4Principal / HR round (15 min) — school fit, board results, NEET coaching stance, salary.
- Two printed CVs + a Class 12 lesson plan
- Original M.Sc, B.Ed, CTET / state TET certificates
- A biology diagram book — you'll be asked to draw one on the board
- One NEET question you can walk through in 90 seconds
Questions with model answers
Grouped by round. Each answer is 2–4 sentences — long enough to be real, short enough to remember. Dots show how often each is asked.
What they're really asking — Do you teach the science as human, not divine?
Cross Tt × Tt → 1 TT : 2 Tt : 1 tt, phenotype 3:1. Segregation happens at meiosis — each gamete gets one allele. He was lucky because his seven traits happened to be on different chromosomes (or far apart), so no linkage muddied the ratio. If he'd picked linked genes, the ratios wouldn't have been clean and genetics would look very different. Great historical context to slip into the lesson.
What they're really asking — Can you diagram fast, clean, and while talking?
Cuticle, upper epidermis, palisade mesophyll (columnar, chloroplast-dense), spongy mesophyll with air spaces, vascular bundle (xylem up, phloem down), lower epidermis with stomata + guard cells. Say the function while you draw it — photosynthesis happens in palisade, gas exchange in stomata, water/food transport in vascular. Drawing while narrating is what the panel wants to see.

Panels don't score creativity — they score structure, board work and closure. This is the skeleton that works.
- Class 12 — Monohybrid cross with a Punnett square
- Class 12 — Human digestive system with a labelled diagram
- Class 11 — Plant transport (transpiration pull) with a demo
- Class 11 — Cell structure via microscope images
- Speed and clarity of diagrams
- Correct terminology used naturally
- Cold-calling by name
- Time management
- One clear takeaway
Real image, news story, or a physical model. Make them predict what they'll see.
State the rule / process in one sentence. Start the diagram on the board — students copy along.
A cross, a case study, or a labelled figure worked out live.
Give them a variation. Circulate; do not sit at the desk.
Cold-call two students. Close with one NEET-style MCQ.
Ask them back — questions for the interviewer
Most candidates freeze at “do you have any questions for us?” These signal that you take yourself seriously.
- How many periods per week does PGT Biology get, and how many practical batches?
- What's your approach to NEET coaching — in-house, external partner, or student choice?
- Do teachers get access to the biology lab outside class hours?
- What's the CPD budget for workshops (HBCSE, ICMR, HHMI)?
- How is the Class 12 batch split between two PGTs?
- What's the appraisal cycle — board results, NEET selections, or feedback?
