AIAG Damage Grade
An AIAG damage grade is a standardized classification of vehicle damage based on the Automotive Industry Action Group's grading framework, used so that the same dent or scratch is graded the same way regardless of who inspects it or when.
The Automotive Industry Action Group (AIAG) publishes widely used standards for vehicle condition and damage assessment. An AIAG damage grade expresses the severity and type of a defect on a consistent scale rather than as a subjective note like "small scratch." That consistency is what makes a grade defensible: two inspectors, or an inspector and a renter, should arrive at the same classification for the same damage.
Standardized grading matters most in disputes and transactions where money turns on condition — rental returns, fleet handovers, lease-end inspections, and remarketing. A graded record turns "is this damage bad enough to charge for?" from an argument into a documented call against a published rubric.
VerifyAI can apply a consistent damage grade automatically as part of a vehicle inspection, alongside a before/after delta that isolates new damage from pre-existing wear. The grade, the delta, and a timestamped audit log together form an evidence package you can export as a PDF condition report. The K1–K5 scale is one commonly used severity expression within this kind of framework.

The K1–K5 scale is a severity grading scale for vehicle damage, running from K1 (minor, often cosmetic wear) through K5 (severe damage typically requiring part replacement), used to classify defects consistently during inspections.
Before/After DeltaA before/after delta is the comparison of an asset's condition at two points in time — typically handoff and return — that isolates what changed, separating new damage from pre-existing wear.
