How is an audit readiness score calculated?

Graded items roll up with partial compliance at half credit: full items plus half the partial items, divided by items assessed, times 100. The worked example's 41 full and 9 partial of 58 is 78.4%.

Why does partial compliance earn half credit?

It is the standard convention of scored process audits, VDA 6.3 being the visible example: full, partial and non-compliance step the credit. The full-compliance share is published beside the score for graders who score harder.

What passing grade should I enter?

The one the coming audit applies. VDA 6.3 grades A from 90% and B from 80; customer schemes commonly pass at 80. Enter the actual bar, because the gap row and both warnings measure against it.

What does it mean if the pass depends on partial credit?

That the pass is fragile. When full compliance alone sits under the bar, the score survives only as long as the auditor awards half credit. The robust state is a full-compliance share that clears the bar by itself.

Supplier Audit Readiness Calculator: Scored Self-Assessment

Turn a pre-audit self-assessment into the score the audit will produce. Enter checklist items, full and partial counts and the passing grade; the score, gap and full-compliance share come back.

What this calculator does

Roll a pre-audit self-assessment into the graded checklist score, with the no-credit share beside it.

Formula used

Readiness score = (full items + 0.5 × partial items) ÷ items assessed × 100
Gap to passing = readiness score − passing grade
Full-compliance share = full items ÷ items assessed × 100
Items not yet compliant = items assessed − full − partial

Inputs explained

Checklist Items Assessed: Questions or requirements the self-assessment graded.
Items in Full Compliance: Items met with current evidence, not intention.
Items in Partial Compliance: Items where practice or evidence is incomplete.
Passing Grade: The bar the audit scheme applies.

How to use the result

Best suited to turning a gap assessment into a score, pricing the prep sprint in points, checking whether a pass survives strict grading.
Real schemes downgrade for single critical findings regardless of the percentage. The score predicts the roll-up, not the audit; sampling finds what self-assessment missed.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
