Integrity Architecture
Closing the Online Exam Invigilation Gap
The “Integrity Gap” is the space between basic automated surveillance and the high-stakes requirements of UK regulators. To bridge this gap and meet the benchmarks of ISO 23988, a specific technical architecture is required.
TrustTest by COSAC provides a managed approach to integrity, moving beyond standard automated proctoring – which was built for scale rather than high-stakes examination invigilation.
The Methodology
DETER
Establishing a psychological and technical barrier to malpractice through multi-factor ID verification and a mandatory 100% invigilation protocol.
DETECT
Deployment of UK-based experts utilising an evolving suite of proprietary tools to identify behavioural nuances and environmental risks that standard AI systems miss.
DO
Ensuring a fully auditable malpractice management process, supported by a defensible evidence trail and a guaranteed 24-hour result turnaround.
Technical Standards & Data Sovereignty
To ensure forensic auditability, our systems prioritise candidate ergonomics and data security:
Integrity FAQ
What can the invigilator app detect?
For a remote invigilation exam, the examination invigilation process can detect unauthorised people and identity mismatches via facial recognition. It flags proximity-based collusion and monitors for suspicious conversations through audio analysis. It also detects unauthorised materials or screen-switching by taking random screen captures and checking for prohibited applications.
How does the invigilator app detect cheating?
TrustTest by COSAC exam invigilation services start with system checks, including AI-assisted identity checks verified by humans. The candidate taking their invigilator online test is monitored via webcam, microphone, and screen-sharing by a human proctor using record and review proctoring. The system tracks eye movement, screen switching, and ambient noise to flag any suspicious behaviour for review by our experienced, UK-based team.
Regulatory Compliance
ISO 23988 emphasises that security must be ‘proportional to the stakes’ of the qualification. In high-stakes sectors, research indicates that automated systems without a continuous human audit trail fail to meet the legal defensibility threshold required by most UK regulators. For directors, this isn’t just a technical glitch – it’s a liability. If a certification is challenged in court, “AI flagged it” is not a defensible legal argument.
