Evidence Standards

A finding rests on evidence. Proctoring produces material of varying quality and treating it uniformly is what produces inconsistent outcomes. The same caution applies to computer monitoring software: computer activity may support an inquiry, but it does not become reliable evidence until provenance, context and interpretation are documented.

The hierarchy

Strongest: a recording showing a second person handling or supplying exam material, with audio.

Strong: a recording showing the student reading from material off-screen, where the material is identifiable.

Moderate: sustained audio of exam content in another voice.

Weak: repeated absence from frame with no other signal.

Very weak: gaze direction, movement, behavioural analysis, connection interruption.

A panel applying this consistently will reach defensible outcomes. One that does not will reach different conclusions on similar facts.

What never stands alone

Any single weak signal.

A score or risk rating produced by the system.

A reviewer's impression without a described observation.

And an unexplained gap, because absence of explanation is not evidence.

Corroboration

A weak signal plus an independent indicator is different from a weak signal alone.

Independent means genuinely separate: answer content that could not have been produced without assistance, a submission identical to another, an admission.

Two weak signals from the same system are not corroboration, because they derive from the same observation and the same limitations.

The student's explanation

Weighed against the evidence rather than required to be proved.

A plausible account that cannot be verified does not thereby become false.

And an implausible account is not itself evidence of misconduct, though it may affect what weight the panel gives other material.

What the recording does not show

Everything outside the frame, which is most of the room.

Which means an inference from what is visible to what was happening has to be stated as an inference, not presented as observation.

Panels should ask explicitly: what is being inferred here, and what else would produce the same picture?

Technical reliability

Frame rates, compression and low light degrade what can be concluded from an image.

A blurred figure in a dark room is not a second person; it is something in a dark room.

Where the recording quality is poor, the evidence is weak, and that should be stated rather than resolved against the student.

Writing the finding

Describe what the recording shows, not what the system concluded.

State the standard applied.

Address the student's explanation specifically.

And identify which category above the evidence falls into, which makes the reasoning checkable on appeal and produces consistency across panels.

What to check

Does your institution have a written evidence hierarchy?

Have panels ever been trained on what proctoring output can support?

Are findings written in terms of what the recording shows?

And has a case ever been dismissed for insufficient evidence — if never, the standard is not being applied.

The point

Two weak signals from the same system are not corroboration, because they derive from the same observation and the same limitations.

Independent means genuinely separate evidence.

Worth stating

Where recording quality is poor the evidence is weak, and that should be stated rather than resolved against the student.

A blurred figure in a dark room is something in a dark room.

Also worth knowing

A plausible account that cannot be verified does not become false, and an implausible one is not itself evidence of misconduct.

The student's explanation is weighed against the evidence rather than required to be proved.

And finally

Write findings in terms of what the recording shows rather than what the system concluded, state the standard applied, and identify which evidential category it falls into.

That makes the reasoning checkable on appeal.

Summary

State what is being inferred and what else would produce the same picture. An inference presented as an observation is the commonest flaw in these findings.

In summary

A written evidence hierarchy produces consistency across panels and makes reasoning checkable on appeal.

Without one, similar facts produce different outcomes, which is the basis of most successful challenges. For wider institutional context, consult Jisc.
