How assessment and verification work

How a score is calculated

dimension_score = Σ(item_score × item_weight) / Σ(item_weight)
confidence      = evidence_coverage × assessment_reliability × review_factor
published_score = round(dimension_score)

Where AI is used, and where it is not

Common questions

Does AI decide whether I pass an assessment?

No. AI applies a written rubric to produce a per-item score, but the weights, the pass thresholds and the aggregation are held in versioned configuration and computed in code. Low-confidence and borderline results are routed to a human reviewer before anything is published, and no badge is issued without human quality review.

What does the confidence value next to a score mean?

Confidence is calculated separately from the score, as the product of how much of the assessment blueprint the evidence actually covers, how reliable the instrument is, and whether a human reviewed the result. A high score with low confidence means we do not yet have enough evidence, not that the person performed poorly.

Can I challenge a result I think is wrong?

Yes. Any score that materially affects your verification status or your access to opportunities can be appealed. An appeal creates a tracked case with a named reviewer who was not involved in the original decision. If a score is overridden, the original result is preserved alongside the new one with the rationale and policy basis recorded.

Do you assess personality, confidence or honesty from my video?

No. We do not use facial expression, emotion inference, honesty detection, attractiveness scoring or accent ranking. Communication is scored on observable criteria such as clarity, structure, professionalism, completeness and expectation setting, using the transcript and a written rubric.

Can I use AI in a practical assessment task?

Yes, and we assess how well you do it. AI fluency is a scored dimension covering whether you use AI effectively, verify its output and understand its limitations. What matters is that you disclose how AI was involved and that the resulting work is good. We do not claim to detect AI-generated work from the artifact alone.

Will my scores change if you update a rubric?

No. Every result is pinned to the assessment version it was taken under, and published assessment versions are immutable. Changing a rubric affects future sessions only. If you want a result under a newer version, you take a reassessment.

How long does verification stay valid?

Each role track has a freshness window. Once your most recent assessment or completed work falls outside it, your profile is marked as due for reassessment rather than presented to employers as current evidence.
