Conduct
Match the integrity controls to the stakes. No surveillance theatre.
Assessment integrity is a layered model in NUADU. Lockdown browser and identity verification at exam start are the defaults. Recorded review and additional integrity layers are opt-in, configurable per assessment, and supported by a DPIA template. Integrity signals are surfaces for a named invigilator — not findings about a candidate.
Assessment integrity has a credibility problem on both sides.
Institutions need credible results. They need confidence that the candidate is who they say they are, that nobody had unauthorised help, and that the result reflects what the candidate actually did. That is a real requirement.
At the same time, heavy-handed proctoring has its own costs. Test anxiety. Accessibility problems. False-positive flags that fall disproportionately on disabled, neurodivergent and non-white candidates. Regulator action against vendors that overreach. A defensible programme matches integrity controls to stakes — not the other way round.
Integrity is real. So is dignity. NUADU is designed around both.
A layered integrity model. Configurable per assessment.
Identity verification at exam start
At exam start, the candidate's face is matched once against the photo they enrolled. This is a one-to-one verification step, not continuous identification of a person from a crowd. The match decision is reviewable.
Browser controls
Lockdown browser, tab switching detection, copy-paste monitoring, application detection. For most assessments, this layer is sufficient and proportionate.
Optional — recorded session review
For higher-stakes assessments, sessions can be recorded for human review. Reviewing is done by a named invigilator after the fact. Anomalies are surfaces — not findings. Candidates are not penalised by the system; the institution's academic-integrity process applies.
Optional — environmental layers
For the highest-stakes use cases (professional licensing, certification body exams), additional environmental layers can be configured. Each layer is documented, requires a DPIA, and is off by default.
Integrity signals — for human review
Where integrity layers are enabled, the system produces signals: a tab switch, an identity-mismatch flag, an unusual pattern. Signals go to a named invigilator. The institution's academic-integrity process decides. The system does not penalise candidates.
Integrity capabilities, configurable per assessment.
Identity verification at exam start
One-to-one match against the candidate's enrolled photo. Reviewable. Not continuous identification.
Lockdown browser
Browser controls including tab detection, application detection and copy-paste monitoring.
Recorded review (opt-in)
Session recording for invigilator review after the fact. Configurable, off by default for low-stakes use.
Anomaly signals
Signals are surfaces for human review. The named invigilator decides. The candidate's appeals process applies.
Accessibility-first
Keyboard navigation and screen-reader labelling on interactive controls. Extra-time accommodations applied automatically without re-verification overhead.
DPIA support
DPIA template, data-flow diagrams, retention policy and sub-processor list for institutional review.
Integrity controls matched to stakes.
A classroom quiz
Lockdown browser and basic tab-switch detection. No cameras. No recording. Proportionate to the stakes. Educators see a clean signal if anything unusual happens, and decide how to handle it.
- Browser controls only
- No cameras, no recording
- Proportionate to formative use
A university final
Identity verification at exam start, browser lockdown, optional session recording for invigilator review on a sample basis. DPIA on file. Candidate appeals process documented.
- Identity verification at exam start
- Optional recording
- Documented appeals process
A professional certification
Identity verification including optional government-ID matching, lockdown browser, recorded review available, additional environmental layers configurable per the certification body's policy. Documentation pack on request.
- Identity verification including government-ID (opt-in)
- Recorded review configurable
- Documentation pack
National examination
Identity verification, lockdown browser, recorded review, named invigilator workflows, candidate due process and complete audit trail. Configurable to match the national programme's policy framework.
- Configurable to programme policy
- Named invigilator workflows
- Complete audit trail for candidate due process
Why this is integrity, not surveillance.
Proportionate by design
From lockdown browser only (formative use) to recorded review with environmental layers (certification body use). The institution chooses the level that matches the stakes.
Identity verification — not identification
One-to-one verification at exam start, against the candidate's enrolled photo. Not continuous identification. Not facial-recognition matching against a database.
Signals, not verdicts
The system produces signals; named invigilators review them; the institution's academic-integrity process decides. Candidates are not penalised by the system, and have the appeals process they would in any other integrity case.
No inference of emotion or intent
NUADU does not infer attention, stress, engagement, confidence or intent from face, voice, gaze or keystrokes. Anomaly signals are objective events — they do not claim to read what the candidate is thinking.
Documented for institutional review
DPIA template, retention policy, sub-processor list, data-flow diagrams. Ready for DPO, works council, candidate appeal and regulator review.
