Choosing an interpreter vendor in Minnesota is less about who has the longest language list and more about who can prove, encounter by encounter, that a qualified interpreter did the work — and produce that proof on demand. The steps below turn a vendor pitch into a concrete evaluation you can run on your own mix of languages, modalities, and encounter types.
The throughline is documentation. A vendor that fills fast but leaves you reconstructing logs before every audit costs more than its rate card suggests. A vendor whose completed sessions produce a signed record as a byproduct of the work saves the staff hours an audit otherwise consumes. For the deeper contrast between the two operating models behind most vendors, see traditional agency vs. dispatch model, and for the national-vs-local question specifically, see national OPI/VRI vendors vs. local on-site dispatch.
Run the pilot before you sign. Everything a vendor claims is testable in 60 days on your real demand, and the languages that break a vendor are the ones you’ll be glad you tested first.
