Assessing 120,000 Teachers Simultaneously: How CENTA Scaled High-Stakes Evaluations with AutoProctor
High volume teacher assessment with customization.
About CENTA
CENTA (Centre for Teacher Accreditation) is a non-profit organization that sets rigorous teacher standards for improving education quality across India. Through bi-annual assessments of teaching competencies, CENTA Standards help educational institutions with teacher recruitment, teacher certification processes, and identifying professional development needs, from online teaching training to post-graduate certification for teachers. Their evidence-based teacher accreditation framework measures pedagogical skills and subject knowledge, enabling data-driven decisions that elevate teaching quality at scale.
The Challenge
CENTA needed to conduct high-stakes teacher evaluations for 100,000-120,000 educators every six months, with peak loads of 30,000 concurrent test-takers. Their previous solution with Mettl couldn't seamlessly integrate with their existing teacher management app, forcing teachers to navigate multiple platforms. They required:
- Native integration within their app for a frictionless teacher experience
- Robust randomization to ensure test security across multiple question banks per subject
- Advanced security measures to prevent test-sharing and impersonation
- Real-time monitoring dashboards for their assessment team
- Automated result transfer to their Assessment Management System (AMS)
The Solution
The AutoProctor Solution
AutoProctor delivered a fully customized assessment infrastructure tailored to CENTA's unique requirements:
- Seamless Embed Integration
Teachers could launch tests directly from CENTA's app with a single click—no separate logins or platform switching required. - Dynamic Link Generation API
Built a custom API allowing CENTA to generate unique, secure test links for each teacher on demand, streamlining their distribution process. - Advanced Question Randomization
Configured multiple question banks per subject with intelligent combination logic, ensuring every teacher received a unique test variant while maintaining assessment validity. - Security Infrastructure
Implemented IP address tracking to detect and flag test-sharing attempts, preventing teachers from forwarding links to unauthorized individuals outside exam centers. - Real-Time Command Center
Custom dashboards enabled CENTA's team to monitor live metrics: candidates who started tests, completion rates, and technical issues—all in real-time during high-stakes assessment windows. - Automated Results Pipeline
Developed a bidirectional API integration that automatically transferred test results from AutoProctor to CENTA's AMS immediately upon completion, eliminating manual data handling.
Results That Scale
- 120,000 teachers assessed bi-annually with zero downtime
- 30,000 concurrent test-takers supported simultaneously without performance degradation
- 100% platform integration eliminating the need for teachers to manage multiple accounts
- Real-time visibility across all assessment centers during peak testing windows
- Instant result transfer to AMS, reducing processing time from days to minutes
By embedding AutoProctor directly into their ecosystem, CENTA transformed their teacher evaluation process from a logistical challenge into a streamlined operation. The combination of seamless integration, robust security, and real-time monitoring enabled CENTA to maintain assessment integrity while dramatically improving the teacher experience. The automated result pipeline ensured that insights reached education leaders faster, accelerating the cycle from assessment to professional development intervention.
Straightforward Integration, Zero Downtime for High Volume Assessments
We conducted an online test for 110,000 users. We integrated AutoProctor into our native app and it was seamless. Their servers held up on all the days and handled the volume without any downtime.
