How far should an auditor travel for an on-site audit?
How certification bodies set travel limits for auditors, when a longer trip is worth it, and how clustering and distance filters keep travel down without breaking competence rules.
Set a maximum distance or travel time per auditor as a filter, then let competence decide within it: the nearest auditor is only the right one if they are competent, impartial and available. Longer trips make sense when they are clustered with other audits nearby. ScheduleAI by Checkfirst shows each candidate's distance, filters by a maximum distance, and packs nearby visits into the same days with travel time counted.
Key takeaways
- A distance limit is a filter, not a ranking.
- Competence always comes first.
- A long trip that serves three audits beats three short ones.
- Count travel time between visits, not only to the first site.
Should there be a fixed limit?
A limit stops absurd trips and protects auditors' time. It should be set per auditor or region, not company-wide, because a rural auditor and a city auditor live in different worlds. Exceptions should be visible, not silent.
How to set a travel policy
- Set a radius or timePer auditor or region.
- Filter, don't rankDistance removes options; competence decides.
- ClusterGroup audits in the same area and window.
- Count the dayInclude travel time between visits.
- Review exceptionsLong trips approved with a reason.

Common mistakes
MythThe nearest auditor is always best.
RealityOnly if competent, impartial and available. Otherwise it is a finding waiting to happen.
MythTravel is only the trip to the first site.
RealityTravel time between same-day visits often costs more.
ScheduleAI by Checkfirst shows each candidate auditor's distance from the site, filters by a maximum distance, and packs nearby visits into the same days with travel time counted, after competence, impartiality and availability are checked.
