A language-access audit is predictable, which means it’s preparable. OCR investigators and Joint Commission surveyors look for the same handful of documents in the same order every time, and the organizations that pass are the ones that treated those documents as operational requirements rather than paperwork. This playbook walks the preparation in the order an audit actually unfolds.
The four documents — a dated plan, interpreter qualification records, the posted notice and taglines, and the encounter log — are the spine of any review. Three of them are usually in place. The encounter log is where most programs fail: they had interpretation but can’t prove it was delivered by a qualified person on a specific date. For the underlying standard and what each document must contain, see the Title VI language-access checklist and Section 1557 interpreter requirements after the 2024 final rule.
The single highest-leverage move is structural: make the encounter log a byproduct of the work. Everything else in this playbook is verification; that one change is what turns the next audit from a scramble into an export.
