NIC common mistakes
NIC · Understand the traps and how to avoid them.
Continuing to produce a fluent-sounding rendition after losing a segment, filling the gap with plausible content instead of stopping to repair (asking for repetition, clarification, or expansion).
Candidates fear that a repair request signals incompetence, and rehearsal habits rarely include recovering from a real breakdown, so the reflex under pressure is to cover the gap rather than expose it.
What to do instead
Build repair into practice deliberately: record yourself interpreting dense monologues, have a partner randomly insert a cough or mumble, and rehearse a short set of stock repair phrases until they are automatic. On scored performance, a clean, brief, meaning-preserving repair costs far less than fabricated content.
Maintaining a processing lag so short that the rendition trails the source by only a word or two, producing omissions, distorted syntax, and sentences that collapse when the source takes an unexpected turn.
Short lag feels safer and mimics the source-language word order, and candidates confuse speed with competence; anxiety about forgetting drives them to keep close to the speaker.
What to do instead
Practice with progressively longer, deliberate lag on monologues of two to four minutes, chunking by proposition rather than by word. Track your own renditions against a transcript and mark every dropped or invented element until the omission rate drops.
Using the same output mode regardless of setting and consumer need, e.g., transliterating in a mental health intake with a Deaf consumer who uses ASL, or using an ASL interpretation when a Deaf professional has requested a close English rendering for a legal proceeding.
Candidates rehearse one mode they feel strongest in and treat mode as a personal preference rather than a decision driven by consumer language preference, setting, and content.
What to do instead
Before each practice scenario, write one sentence naming the setting, the consumer's stated language preference, and the mode you will use, then justify it. Practice switching modes mid-scenario when a consumer requests it.
Producing renditions with flat affect and no preservation of register, prosody, or speaker stance, so a furious complaint, a joke, or a formal legal caution all come out sounding identical.
Attention is consumed by lexical and grammatical decisions, leaving no capacity for paralinguistic features; candidates also carry a mistaken belief that neutrality means emotional flatness.
What to do instead
Practice shadowing and then interpreting passages that vary widely in register and emotion, and record yourself to check for pitch, pace, and intensity. Deliberately identify the speaker's stance before you begin rendering and treat it as part of the message.
Rendering form instead of meaning, i.e., following the source word order and vocabulary closely enough that idioms, implied subjects, and culturally loaded terms come out literal and confusing ("English on the hands" style output).
Candidates equate fidelity with one-to-one correspondence and do not trust their command of the target language enough to restructure; this is especially common when the source uses specialized or technical vocabulary.
What to do instead
Do systematic back-translation exercises: interpret a passage, then have a partner interpret it back and compare meaning with the original. Practice expansion and compression drills that require adding implied information in one direction and condensing redundant phrasing in the other.
Treating the ethical code as a rigid rulebook, picking the answer that sounds most virtuous rather than analyzing the situation's demands, the options available, and the consequences of each option.
Exam prep often reduces ethics to memorized prohibitions, so candidates look for the answer that matches a slogan instead of reasoning through the scenario as presented.
What to do instead
For every scenario, write out at least three plausible courses of action and the likely consequence of each before choosing. Practice naming the demands in play (environmental, interpersonal, intra personal) and identifying which one is driving the dilemma.
Defaulting to a personal value or relationship over the assignment, e.g., disclosing information to a familiar Deaf community member, accepting an assignment involving a friend or relative, or letting a prior relationship shape how a conflict is handled.
Small-community overlap is normal and candidates underestimate how visibility and familiarity create pressure; loyalty to community feels ethically superior to detachment.
What to do instead
Study dual-role and conflict-of-interest guidance and rehearse a decline script for assignments involving friends, family, or ongoing community roles. In scenarios, ask explicitly whether a relationship exists that would compromise impartiality, then name the disclosure or withdrawal step.
Slipping into advocate, helper, or educator behavior during a scenario, e.g., answering a question that was directed to the Deaf consumer, explaining the consumer's needs to a hearing provider, or adding advice not present in the source message.
Candidates enter the field with strong service motivation, and a scenario with an obvious injustice triggers the impulse to fix rather than to interpret; the distinction between role and advocacy is often undertheorized.
What to do instead
Practice a strict first-person rule in role-plays and review recordings for any utterance not traceable to a speaker. Study the distinction between interpreting within a role and legitimate advocacy outside the assignment, and be able to state which one you are doing and why.
Ignoring business-practice content entirely, so questions on fees, cancellation and no-show terms, contracts, invoicing, taxes, insurance, or screening a referral for competence are answered by guesswork.
Candidates invest all study time in performance and ethics vignettes and assume business knowledge is common sense or will be learned on the job.
What to do instead
Build a one-page reference of standard freelance terms (rate structures, minimum charges, cancellation windows, deposit and payment timelines, self-employment tax obligations, liability coverage) and drill scenario questions that hinge on those terms.
Arriving at a scenario without a preparation or logistics plan: not identifying the participants and goals beforehand, not arranging team interpreting or seating and sight lines for a long or visually demanding assignment, and not planning how to handle a speaker who reads rapidly from a script.
Candidates treat each question in isolation and focus on the moment of interpretation, overlooking that competence includes pre-assignment preparation and managing the physical and team environment.
What to do instead
For every practice scenario, write a pre-assignment checklist: setting and participants, content and terminology to review, mode and consumer preference, physical setup, breaks and team needs, and a plan for a script or rapid delivery. Review the checklist before answering any logistics-type item.
