Conduit role

The interpreter's default role: render everything each speaker says faithfully, in the first person, adding and omitting nothing. The other three roles are exceptions, so an interpreter who steps out of the conduit role needs a reason and must say so out loud to both parties.

Clarifier role

Used when a term, register, or concept will not carry across: the interpreter asks the speaker to rephrase or explain, then interprets that explanation. The tested distinction is that a clarifier prompts the speaker to explain and never supplies the explanation out of the interpreter's own knowledge.

Culture broker role

The interpreter briefly surfaces a cultural belief or practice that is blocking understanding, transparently and to both parties. It means offering information about a possible cultural difference, not speaking for the patient, endorsing the belief, or telling the provider what to do about it.

Patient advocate role

The most intrusive role: the interpreter leaves the conduit role to act when a patient's health, safety, or dignity is at risk, and announces the switch. Because advocacy strains impartiality, it is a last resort used only after less intrusive options have failed.

Ethics principle: confidentiality

Everything learned in an encounter stays in it, including the fact that the encounter took place. Consequence: no case talk in hallways or elevators, no summarizing for a relative in the waiting room, and no sharing details with colleagues who are not part of that patient's care team.

Ethics principle: accuracy and completeness

Render the whole message, including tone, register, profanity, insults, and statements the interpreter believes are factually wrong. Nothing is softened, summarized, or quietly corrected, and the interpreter's own errors are corrected openly. This principle is also where false cognates bite: Spanish 'constipado' means having a cold, not constipated.

Ethics principle: impartiality

The interpreter keeps personal opinions, beliefs, and reactions out of the encounter. Consequence: when a patient asks 'what would you do?', the interpreter interprets the question to the provider rather than answering it, no matter how strong the personal view.

Ethics principle: conflict of interest

Any personal, financial, or professional interest that could bias performance must be disclosed, and usually requires withdrawing from the assignment: interpreting for a relative or friend, or for a case in which the interpreter has a stake. Disclosure is required even when the interpreter believes they can stay neutral.

Ethics principle: scope of practice

The interpreter interprets. They do not advise, counsel, diagnose, explain medical information, or perform clinical tasks such as taking vital signs. Consequence: even when the interpreter knows the answer to a patient's question, the question goes to the provider.

Ethics principle: disqualification and impediments to performance

An interpreter must withdraw when something prevents competent work: unfamiliar terminology or dialect, fatigue, illness, or emotional involvement such as a child abuse or death notification case that mirrors their own history. Continuing while impaired is an ethics breach, not dedication.

Ethics principle: professional courtesy

Interpreters treat colleagues, providers, and staff with respect and support each other in team or relay assignments. A colleague's interpreting error is corrected transparently and on the record, not by silently reworking the message or by criticizing the colleague in front of the patient.

Ethics principle: professional development

The standing duty to keep interpreting skills and medical knowledge current. NBCMI turns this duty into a renewal rule: 3.0 CEUs, equal to 30 contact hours of approved training, before the credential expires (4 years for a Hub-CMI, 5 years for a CMI).

Modesty and gender concordance in care

In many cultures a patient may be unwilling to undress for, be examined by, or discuss intimate topics through a person of the opposite sex, including the interpreter. The interpreter transparently conveys the discomfort or the request for a same-sex clinician or interpreter, flagging the pattern as a culture broker if needed; deciding how to accommodate it remains the provider's call.

Limited English Proficient (LEP)

A person who does not speak English as a primary language and has a limited ability to read, speak, write, or understand it. The label carries legal weight: under Title VI of the Civil Rights Act and Section 1557 of the ACA, LEP status is what triggers a federally funded provider's duty to offer qualified language assistance free of charge — the patient is never billed for the interpreter.

Familial and relational structures in healthcare decisions

Many families make health decisions collectively or route information through an elder or the head of household rather than through the patient alone. The interpreter conveys what is said and may flag the pattern as a culture broker, but the provider decides how to reconcile it with consent and privacy requirements.

Handling folk-illness and traditional-healing terms

Patients often describe illness in culturally specific terms or mention traditional remedies such as cupping or herbal preparations. Interpret the patient's own words, then note transparently that the term has no direct biomedical equivalent, instead of substituting the diagnosis you assume the patient means.

Tendon vs ligament

A tendon connects muscle to bone; a ligament connects bone to bone. Consequence: a torn ligament (for example the ACL) and a torn tendon (for example the Achilles) are different injuries with different repairs, so the two words can never be swapped in either language.

Ureter vs urethra

The two ureters carry urine from the kidneys down to the bladder; the single urethra carries urine from the bladder out of the body. One syllable separates them, and a stone lodged in the ureter is a very different clinical picture from an obstruction in the urethra.

Central nervous system vs peripheral nervous system

The CNS is the brain and spinal cord; the PNS is every nerve outside them. Consequence: peripheral neuropathy, often diabetic, is a PNS problem affecting the feet and hands, while stroke, meningitis, and multiple sclerosis lesions are CNS problems.

Alveoli

The microscopic air sacs at the end of the bronchioles where oxygen passes into the blood and carbon dioxide passes out. Emphysema destroys alveolar walls, which explains why a patient can still move air in and out yet remain short of breath and poorly oxygenated.

Proximal vs distal

Proximal means nearer to the trunk or point of attachment; distal means farther from it. Consequence: a distal radius fracture is at the wrist end of the forearm and a proximal humerus fracture is at the shoulder, so reversing the terms relocates the injury to the other end of the limb.

Insulin vs glucagon

Two pancreatic hormones with opposite jobs: insulin moves glucose from the blood into cells and lowers blood sugar, while glucagon releases stored glucose and raises it. Glucagon is the emergency rescue treatment for severe hypoglycemia, so confusing the pair in patient teaching is dangerous.

Sign vs symptom

A sign is objective and observable by the clinician, such as fever, rash, or blood pressure; a symptom is subjective and reported by the patient, such as pain, nausea, or dizziness. Symptoms reach the chart only through the interpreter, so the patient's own descriptors and intensity words must survive intact.

Acute vs chronic

Acute means sudden onset and short duration; chronic means persisting for months or years. Consequence: 'acute on chronic' is not redundant, it signals a sudden worsening of a long-standing condition, and flattening it to 'chronic' hides the emergency from the listener.

Benign vs malignant

A benign tumor stays local and does not invade or spread; a malignant tumor invades nearby tissue and can metastasize to distant sites. This single word decides whether the conversation is about watchful monitoring or about cancer treatment.

Dysphagia vs dysphasia vs dyspnea

Dysphagia is difficulty swallowing, dysphasia is impaired language production or comprehension, and dyspnea is difficulty breathing. They differ by one or two sounds and send the workup to gastroenterology, neurology, or pulmonology respectively.

Suffixes -itis, -osis, and -algia

-itis means inflammation (hepatitis, appendicitis), -osis means an abnormal or degenerative condition without inflammation (cirrhosis, fibrosis), and -algia means pain (neuralgia). Decoding the suffix lets an interpreter reason out an unfamiliar term rather than guessing at it mid-encounter.

Suffixes -ectomy, -otomy, and -ostomy

-ectomy is surgical removal (appendectomy), -otomy is cutting into (tracheotomy), and -ostomy is creating an opening or stoma (colostomy). One syllable separates 'we took it out', 'we cut into it', and 'you will have a permanent opening', so the endings must be rendered precisely.

Generic name vs brand name

The generic name is the drug's nonproprietary name (acetaminophen); the brand name is a manufacturer's trademark (Tylenol). Interpret the name actually spoken, because substituting the brand a patient knows from another country can point to a different active ingredient or strength entirely.

Routes of administration: PO, IV, IM, SubQ, SL, PR

PO is by mouth, IV into a vein, IM into muscle, SubQ under the skin, SL under the tongue, and PR rectally. Route changes both dose and speed of onset, so generic verbs like 'take' can never stand in for 'inject' or 'place under the tongue'.

Side effect vs adverse reaction vs drug allergy

A side effect is an expected secondary effect such as drowsiness; an adverse drug reaction is unintended harm from the drug; a true allergy is an immune response such as hives, swelling, or anaphylaxis. Consequence: letting 'nausea' be recorded as an allergy can remove an entire drug class from a patient's options for life.

CT scan vs MRI

A CT builds images from X-rays and is fast, making it the emergency choice for trauma and bleeding; an MRI uses a strong magnetic field and radio waves for soft-tissue detail and takes far longer. That magnet is why MRI screening questions about implants, pacemakers, and metal fragments are safety questions, not paperwork.

NPO

From nil per os, 'nothing by mouth': no food, no drink, and often no oral medication after a stated time, typically before surgery, sedation, or certain tests. Rendering it loosely as 'do not eat' invites the patient to drink coffee or take pills and have the procedure cancelled.

Endoscopy vs EGD vs colonoscopy

Endoscopy is the general term for viewing inside the body with a scope; an EGD, or upper endoscopy, examines the esophagus, stomach, and duodenum; a colonoscopy examines the large intestine. The preparation instructions and the anatomy differ, so the specific term must be preserved.

Systolic vs diastolic blood pressure

Systolic, the top number, is arterial pressure while the heart contracts; diastolic, the bottom number, is the pressure between beats. Under the 2017 ACC/AHA guideline, below 120/80 mmHg is normal and 130-139/80-89 mmHg is stage 1 hypertension, so reversing the numbers changes the diagnosis.

Gravida and para (obstetrics)

Gravida is the number of pregnancies and para the number of births carried to viability, so G3P1 means three pregnancies and one birth. These counts drive risk assessment and often lead into questions about losses, so they must be rendered exactly rather than approximated.

Cancer staging vs grading

Staging, commonly TNM for tumor size, node involvement, and metastasis, describes how far a cancer has spread; grading describes how abnormal the cells look under the microscope. A grade 3 tumor is not a stage 3 cancer, and swapping the words misstates the prognosis conversation.

Triage in the emergency department

Triage sorts patients by clinical acuity rather than arrival order, so a chest-pain patient who arrives later is seen first. Interpreting this explanation accurately is often what keeps a waiting family from concluding they are being discriminated against.

Angina vs myocardial infarction vs cardiac arrest

Angina is chest pain from reduced blood flow without permanent damage; a myocardial infarction is blocked flow that kills heart muscle; cardiac arrest is the heart ceasing to pump. They are three different events with three different responses and are not interchangeable in any language.

Ischemic vs hemorrhagic stroke

An ischemic stroke is caused by a clot blocking blood flow; a hemorrhagic stroke is caused by bleeding into the brain. Treatment runs in opposite directions, since clot-dissolving drugs help the first and can be fatal in the second, so onset details and the 'last known well' time must be interpreted precisely.

Sprain vs strain vs fracture

A sprain injures a ligament, a strain injures a muscle or tendon, and a fracture is a broken bone; an open or compound fracture breaks the skin and is an infection emergency. Patients often use one everyday word for all three, so the interpreter renders exactly what each speaker said.

Hemodialysis vs peritoneal dialysis

Hemodialysis filters blood through a machine, usually in about three sessions per week at a center using a fistula, graft, or catheter; peritoneal dialysis uses the lining of the patient's own abdomen with exchanges performed at home. The access sites, schedules, and home-training instructions are entirely different.

Type 1 vs type 2 diabetes, and what A1C measures

Type 1 is autoimmune loss of insulin production and always requires insulin; type 2 is insulin resistance managed with lifestyle change, oral medication, and sometimes insulin. A1C reflects average blood glucose over roughly the previous two to three months, so it cannot be improved by fasting on the morning of the visit.

Interpreting in psychiatry and mental health

How something is said is clinical data: tangential speech, flat affect in wording, delusional content, and statements about self-harm are interpreted as spoken, in the first person, without tidying grammar or softening content. Cleaning up the language erases the findings the clinician is assessing.

Consent vs assent in pediatrics

A parent or legal guardian gives consent, which is the legally binding permission; a child gives assent, an age-appropriate agreement to go along with the plan. The interpreter interprets for whoever is speaking and never becomes the child's voice, and federal rules bar relying on a minor child as the interpreter outside a genuine emergency.

Informed consent before a procedure

Informed consent is a conversation covering the procedure, its risks, benefits, alternatives, and the right to refuse, and only then a signature. The interpreter interprets that conversation and sight translates the form; obtaining consent and answering the patient's clinical questions belong to the clinical team.

The three standards documents NBCMI names

The IMIA Standards of Practice, the NCIHC National Standards of Practice, and the CHIA Standards. They are the profession's shared statement of how ethical principles are carried out in practice, and exam items are written against these documents rather than against any single employer's policy.

Consecutive vs simultaneous interpreting vs sight translation

Consecutive means interpreting after each speaker pauses and is the healthcare default; simultaneous is near real time and usually reserved for one-way information; sight translation is reading a written document aloud in the other language. NBCMI's oral exam tests only consecutive interpreting and sight translation from English into the target language, not simultaneous, written translation, or sight translation into English.

National CLAS Standards

The 15 National Standards for Culturally and Linguistically Appropriate Services published by the HHS Office of Minority Health. Standard 1 is the Principal Standard (equitable, understandable, respectful care), and Standards 5-8 cover Communication and Language Assistance, the section that governs interpreter services. CLAS itself is guidance, not statute — the enforceable language-access duty behind it comes from Title VI and ACA Section 1557.

HIPAA Privacy Rule as it applies to interpreters

The Privacy Rule protects individually identifiable health information and limits use and disclosure to the minimum necessary for the task. An interpreter working for or on behalf of a covered entity handles protected health information, so encounter notes are destroyed afterward and details are never repeated, texted, or posted.

Frequently Asked Questions

How many questions are on the NBCMI CMI written exam?

The written exam is a computer-based multiple-choice test with 51 scored questions and a 75-minute limit, offered only in English. NBCMI's February 13, 2026 Candidate Handbook adds that five to ten unscored pretest questions may also appear, and that the time spent on them does not count against the 75 minutes.

What score do I need to pass the CMI exams?

The written exam requires 75%, a cut score set through PSI's standard-setting study using a modified Angoff procedure. Oral exam passing scores vary by language: NBCMI's program FAQ lists 70% for Spanish, Cantonese, Korean, and Russian, 80% for Mandarin, and 65% for Vietnamese. Candidates are not graded on a curve — performance is measured against a fixed standard, so everyone who reaches the cut score passes.

What is the difference between the Hub-CMI and the CMI?

Passing the written exam earns the Hub-CMI, a non-language-specific credential available to interpreters of any language. Full CMI certification also requires passing the oral exam, which exists in six languages: Spanish, Russian, Mandarin, Cantonese, Korean, and Vietnamese. If the oral exam exists in your language, the Hub-CMI expires in 2 years and cannot be renewed.

What happens if I fail the CMI written or oral exam?

NBCMI requires a 3-month waiting period before retaking either exam, and the retake fee and application procedure are the same as the first attempt ($190 written, $300 oral). After 3 retakes you are limited to 1 attempt per calendar year, and you may not exceed 5 attempts in total.

What does CMI certification cost and how is it renewed?

Fees effective January 1, 2025 are a $40 non-refundable registration fee valid for one year, $190 for the written exam, and $300 for the oral exam. Renewal costs $300 and requires 3.0 CEUs (30 contact hours) of approved medical-interpreting education, submitted at least 45 days before the credential expires.
