Performance-Based Interpreting (All Languages)
The performance-based domain is where the exam stops asking what you know and starts asking what you produce. You render healthcare dialogue in English and your target language, and trained raters who work in that language pair score the recording against an analytic rubric. Because the credential covers all languages, nothing is scored by keyword matching: every judgment is about meaning transfer and professional conduct inside a real encounter.
How raters read a rendition
Raters break the source into propositions and ask three questions. Did the meaning survive? Did anything appear that the speaker never said? Would a patient hear this as a professional interpreting, or as a bilingual person paraphrasing? The recurring error families are:
- Omission - a proposition, qualifier, or instruction disappears.
- Addition - explanation, reassurance, or a diagnosis the speaker did not give.
- Distortion - negation flipped, subject and object swapped, laterality reversed, modality softened (must → should), hedging stripped out.
- Register and delivery - choppy phrasing, fillers, or a shift between formal and casual that changes how the news lands.
Numbers, doses, units, frequency, route, allergies, and every "no" or "not" are safety-critical; they are not weighed like a dropped adjective.
Rules that hold in every language pair
- First person, complete, no summarizing, no editing, no answering for either party.
- Keep each number glued to its unit and schedule: 400 milligrams every six hours, not 400 every six hours.
- State negation and modality outright. Languages mark these differently, so an implicit equivalent is a distortion.
- Manage the encounter - ask for clarification, ask speakers to pause, stop side conversations - but keep the intervention short and separate from the rendition.
- For sight translation, read by clause, carry over headers, bullets, and warnings, and never skip a "do not" line.
Worked example
Source: "Take ibuprofen 400 milligrams every six hours as needed, but no more than 1,200 milligrams in 24 hours, and only with food." A weak rendition keeps the dose but drops no more than and only with food. Reasoning: the ceiling is a toxicity guard and the food instruction prevents gastric harm; both are explicit prohibitions in the source and must be explicit in the target. A strong rendition preserves the dose, the interval, the as-needed condition, the 24-hour ceiling, and the food restriction, in the target language's normal instruction register.
Traps that cost marks
Rendering "denies pain" as "has no pain" when the source is a reported negative; converting milligrams to grams; turning "we should consider" into "you need"; adding reassurance during a bad-news segment; and sight-translating discharge instructions while silently skipping the follow-up appointment line.
