India conducts over 400 major government recruitment exams annually — from central bodies like UPSC and SSC to state-level PSC and departmental exams. The shift from paper to digital is accelerating, driven by the NRA's (National Recruitment Agency) push for a common entrance test infrastructure.
Deployment 1: State Health Department (Maharashtra)
72,000 candidates for 3,200 posts. Paper exams had previously taken 11 weeks from exam day to final merit list. Digital delivery, auto-marking, and instant rank generation cut this to 6 days. The biggest challenge: candidate familiarity with touchscreen devices. Solution: free practice sessions at district-level CBT centres 2 weeks before the exam.
Deployment 2: Rajasthan Police Constable Exam
1.2 million candidates across 140 exam centres. Key lesson: plan your bandwidth carefully. Even with a locally-cached exam delivery model (questions downloaded to centre servers, no internet required during exam), centre check-in and biometric authentication at scale requires robust network planning. 40-minute check-in delays on day 1 were eliminated by day 3 with staggered reporting times.
Deployment 3: Tamil Nadu Teacher Eligibility Test
The TN-TET digital pilot ran in parallel with the paper exam for 18 months. This dual-track approach allowed candidates to opt in voluntarily while building institutional confidence. By year 2, 84% of candidates chose digital. The paper track was retired in year 3.
Universal lessons
Every deployment confirmed three things: start with a small-scale pilot, invest in candidate helplines during the exam, and never release results until the review committee has cleared all High severity proctoring flags.
