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

TrustTest’s 'Deter, Detect, Do' framework for remote exam invigilation, showing a three-stage strategy to create psychological barriers to malpractice, utilize human-led online invigilator detection, and provide a defensible evidence trail for ISO 23988 compliance.

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:

LTI 1.3 Compliance

Fully compliant for seamless, two-way interoperability with your LMS, managing the end-to-end flow from registration to the automated return of results.

Forensic Audit Trail

Every online invigilated exam is built to meet rigorous regulatory standards, supported by 100% human-led review and a robust QA oversight process for every individual session.

Record and Review Proctoring

TrustTest by COSAC utilises this gold-standard model to provide a verifiable statement of fact for every “Pass”.

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.
