Educational Assessment Revolution
TestnTrack – Jaipur-based assessment platform for K-12 schools & coaching institutes
AI Native Teams Growth Office
Manual teacher network caused 3-day delays & rising grading costs
- — 95% faster results
- — ₹10L/mo OPEX cut
- — 98.5% accuracy
- — 85% cost reduction
“AI-grading let our teachers focus on teaching, not tallying bubbles.”
Pain Narrative
TestnTrack relied on hundreds of part-time teachers who manually tallied OMR bubbles, read every handwritten answer, and entered marks. A single mid-term (10,000 papers) still took 3 days to publish results, chewing through overtime budgets and frustrating parents who wanted instant feedback. Scaling to new districts meant hiring more graders, not better tech.
Legacy Tasks- —Manually tally OMR bubbles per sheet
- —Read and score every handwritten answer
- —Enter marks manually, then reconcile errors
Hybrid AI Assessment Engine
3-week audit & SOP blueprint
Hybrid AI Assessment Engine
Vision model detects sheet layout, classifies filled bubbles, returns JSON map with 99% accuracy—no dedicated scanners required.
Vision-transformer + LLM layer extracts handwriting, decomposes model answer into key-points, awards marks for matches, and spot-scores extra insights.
Strategy that Delivered Results
- — Input ingestion: React-Native app + offline queue
- — OCR core: PyTorch + Detectron2, quantised for on-device
- — Subjective scorer: Vision + LLM + custom attention head
- — Orchestration: AWS Fargate micro-services, Step Functions
- — Security: VPC isolation, AES-256 at rest, logs to ELK
- — 15 stakeholder interviews, 12 classroom shadow-sessions
- — 22 manual steps → consolidated into 6 automated stages
- — Pilot (2 schools, 8 teachers) → phased rollout (45 schools) in 7 weeks
- — On-site workshops; feedback loop auto-tags mismarked answers for model retrain
