The CCHI CHI-Mandarin performance exam has four task types: four bidirectional consecutive dialogs (70% of the score), two one-play simultaneous items (17%), three English sight translation passages (11%), and one written translation multiple-choice question (2%), completed in 60 minutes. Your recordings are rated on three equally weighted scales, and you pass at a scaled score of 450. Build practice around full consecutive dialogs, then rotate the other three modes.
What this exam is and the two-step path to it
The CHI-Mandarin exam is the bilingual performance step of CCHI's Certified Healthcare Interpreter credential for Mandarin, and you must pass the CoreCHI knowledge exam first, then pass the CHI exam within 12 months.
CCHI offers the Certified Healthcare Interpreter (CHI) credential for Spanish, Mandarin, and Arabic. To earn it, you take two exams: the CoreCHI, a multiple-choice professional knowledge exam in English, and the language-specific performance exam, which for you is the CHI-Mandarin.
The sequence matters. CCHI requires you to pass the bilingual performance CHI exam within 12 months of passing CoreCHI. If that window closes without a pass, your CoreCHI score expires and you must retake CoreCHI before attempting the CHI exam again. Plan your performance-exam preparation against that clock rather than treating the two exams as unrelated.

The four tasks and how they count
The exam has four sections with fixed weights: consecutive interpreting at 70%, simultaneous at 17%, sight translation at 11%, and one written translation question at 2%.
The current specifications, effective October 1, 2023, define the full structure. The exam is computer-delivered. Consecutive and simultaneous tasks use recorded speech; sight translation uses written passages and spoken responses. The final translation task requires an on-screen multiple-choice answer.
Because consecutive dialogs carry 70% of the score, they deserve the largest share of your practice time. That said, CCHI states the total score comes from the full examination, not an average of sections, so the smaller tasks still move your result. The table below gives each task's format so you can rehearse under the real constraints.
| Task | Format and direction | Weight | Key constraints |
|---|---|---|---|
| Consecutive interpreting | Four bidirectional patient-provider dialogs, English to and from Mandarin | 70% | 14-24 utterances per dialog; each utterance up to 35 words; up to two listens per utterance |
| Simultaneous interpreting | Two unidirectional items: one into Mandarin, one into English | 17% | Up to 2 minutes (180-220 words) each; played once; respond while listening |
| Sight translation | Three short English passages from different US healthcare document types, read aloud in Mandarin | 11% | Each passage no more than 3 sentences, up to 45 words total |
| Written translation | One multiple-choice question: an English passage with four Mandarin translation options | 2% | English passage of 85-110 words; only one option is accurate |

Test-day format and logistics
The exam runs 60 minutes after a separate 15-minute tutorial, is forward-only with no answer review, and is delivered at proctored test centers in the USA and Canada.
Before the timer starts, you complete an audio check and have 15 minutes to read directions and try a tutorial on the exam interface. That preparatory time does not count toward the 60 minutes of exam time. During the exam, a countdown timer shows the minutes remaining, and responses are saved in real time, so the test submits automatically at 60 minutes even if you have not finished.
The exam is forward-only: you cannot go back or listen to your own recorded responses. Within a consecutive item, you may listen to an utterance up to twice; simultaneous audio plays once. You receive paper and pencil for notes, and the proctor collects and shreds them afterward. No breaks are allowed; leaving the testing room without a pre-approved ADA accommodation ends the exam.
Scores are emailed within 6-8 weeks after the last date of the whole testing window, not after your individual test date, so expect the wait to depend on when the window closes. If anything goes wrong at the test center that you believe affects your result, tell the proctor before leaving and also email CCHI in writing within 24 hours.

How your recordings are scored
Each recorded response is rated on three equally weighted scales: lexical content and accuracy, grammar, and quality of speech. The exam is scaled from 300 to 600, and 450 is the passing score.
Lexical content and accuracy measures how completely you preserve units of information, meaning the individual words, phrases, or concepts that carry a single idea. Omissions, additions, inaccurate renderings, and changes in the register of speech all count as errors here. Grammar covers how sentences hold together in both languages, including verb tense, agreement, pronouns, and target-language word order. Quality of speech addresses delivery: false starts, hesitations, repeated self-repairs, pronunciation, and pace that hinders understanding.
Your total is a scaled score between 300 and 600, with passing set at 450, and statistical equating keeps that standard comparable across test forms. The score report also shows percentage results for the subdomains: consecutive, simultaneous, and sight translation/translation. CCHI is explicit that these percentages carry no pass or fail status, are not averaged into your total, and should be read cautiously because each subdomain contains few items. Use them to find weak modes, not to conclude you passed a section.

Eligibility and proving your Mandarin proficiency
You must be at least 18, hold a US high school diploma or equivalent, complete 40 hours of healthcare interpreter training, and document proficiency in both English and Mandarin before you can test.
The baseline requirements apply to every CCHI applicant: minimum age 18, at least a US high school diploma or GED or the equivalent from another country, at least 40 hours of healthcare-specific interpreter training, and demonstrated proficiency in English and your language of service. CCHI does not accredit or endorse beginner training programs, and it cautions applicants to question any course that guarantees exam success.
For the Mandarin credential specifically, CCHI accepts several forms of LOTE (language other than English) proficiency evidence. Options include a high school diploma or transcript showing instruction in Mandarin, a US diploma with the Seal of Biliteracy, a degree from a college taught in Mandarin, a bachelor's or master's degree in Mandarin, or a passing score on a language proficiency test from a CCHI-approved vendor at Advanced-Mid on the ACTFL scale or 2+ on the ILR scale. Successful passage of an established certification exam with a language-specific performance test can also qualify.
Applications are submitted online with supporting documents uploaded electronically, typically reviewed within 10 business days. One logistical point worth planning around: the CHI performance exams are administered only at physical test centers within the USA and Canada, so budget travel time if no center is near you.
- Confirm your 40 hours of training are specifically healthcare-related before applying.
- Gather Mandarin proficiency documentation early; translated documents must include the English translation in the same file.
- Apply through your CCHI profile and schedule the CHI exam only after CoreCHI is passed, keeping the 12-month limit in view.

Consecutive interpreting: the section that decides most of your score
Four bidirectional dialogs dominate the exam, so practice complete two-way conversations at exam length, with disciplined note-taking and a fixed purpose for each of your two listens.
Each dialog is a recorded conversation between a patient and a healthcare provider switching between English and Mandarin. At 14 to 24 utterances per dialog, with individual utterances up to 35 words, the challenge is holding accuracy across a long exchange, not translating one polished sentence. Drill full-length dialogs rather than isolated phrases.
Use the allowed two listens deliberately: a first pass for meaning and notes, and a second only to verify specific items such as numbers, medication names, or negations. You will have paper and pencil at the test center, so build your note system on paper from the start. After each practice dialog, list every unit of information you reproduced and every one you dropped, added, or distorted, because those are exactly the errors the lexical accuracy scale penalizes.
Professional practice standards provide a useful accuracy checklist alongside the exam rubric. The NCIHC National Standards of Practice call for rendering all messages completely, without adding, omitting, or substituting, replicating the speaker's register and tone, and managing the flow of communication. Use those accuracy principles to review your recordings. The NCIHC standards are background practice guidance here, not an additional weighted CHI domain or permission to request live clarification from a recorded speaker.

Simultaneous, sight translation, and the written question
Simultaneous items play once and must be interpreted while listening, sight translation asks you to speak short English document passages in Mandarin, and one multiple-choice item tests written translation judgment.
The two simultaneous items are unidirectional, one from English into Mandarin and one from Mandarin into English, each up to two minutes and about 180 to 220 words. CCHI notes English items run at roughly 120-150 words per minute, which corresponds to about 180-225 Chinese words or syllables per minute on the Mandarin items, an average conversation-level speed. Because each item plays once and you must speak while listening, practice listening and speaking concurrently, then review your recording for omissions, additions and delivery problems.
Sight translation gives you three brief English passages, each no longer than three sentences and up to 45 words, drawn from different types of US healthcare documents. Read the whole passage before speaking, mark the numbers, negations, and conditional instructions, and convert written document phrasing into natural spoken Mandarin rather than decoding word by word.
The final multiple-choice item shows an English passage of 85 to 110 words with four Mandarin translations, only one accurate. A reliable method is to form your own understanding of the source first, then check each option against it: does every unit of meaning survive, was anything added, and did negation or conditionality shift? The exercise below practices detecting changed meaning; it does not claim to reproduce the design of official distractors.

Practice meaning preservation with a negation audit
A single reversed negation or added cause changes the message even when the rendition sounds fluent, so audit practice renditions unit by unit against the source.
The scoring scales count meaning distortions: an inaccurate translation of a unit of information or an addition counts against lexical accuracy, and professional standards require rendering messages without substituting meaning. The exercise below uses English only, so you can train the checking habit itself. It is an analysis exercise, not a simulation of the bilingual exam, and working through it on paper does not measure interpreting skill.
Practice exercise
A patient says in English: "I did not take the tablets this morning because I felt nauseated." A practice rendition, when rendered back into English, reads: "I took the tablets this morning and they made me nauseated." Using only meaning analysis, identify every unit of information this version changed, then write a faithful English meaning statement of the patient's original message.
Show answer
Two distortions stand out. First, the negation is reversed: the patient did not take the tablets, but the rendition says the tablets were taken. Second, a causal claim is added and inverted: the patient gives nausea as the reason for not taking the tablets, while the rendition claims the tablets caused nausea, a relationship the source never states. What is preserved is the time frame (this morning) and the topic (tablets and nausea). A faithful statement keeps the patient as the speaker, the negation on the taking, and the cause attached to the not-taking: "Because I felt nauseated, I did not take the tablets this morning."
Under CCHI's lexical content and accuracy scale, omissions, additions, and inaccurate translation of a unit of information are errors, and register changes count on the same scale. The NCIHC accuracy standard likewise requires rendering all messages without adding, omitting, or substituting. The reversed negation changes the clinical reality the provider hears (a patient who took medication versus one who skipped it), and the added causal claim puts words in the patient's mouth. Checking a rendition unit by unit, speaker, time, negation, number, and stated cause, against the source is the audit habit to apply to every recorded response you review in practice.

Preparation priorities and next steps
Weight your practice toward consecutive dialogs, self-check recordings against the three rating scales, keep all four modes rotating, and rely on CCHI's official pages for scheduling and fees.
A sustainable routine, offered as study advice rather than an official requirement: give consecutive dialogs the largest weekly share, record every practice response, and judge each recording separately on lexical accuracy, grammar, and speech quality, the same three lenses raters use. Keep short regular rotations through simultaneous work, sight translation, and translation comparison so no mode goes cold. As you review, note register explicitly, since changes in register count as accuracy errors and the exam outline lists maintaining register as a skill for every task.
For everything outside the tested skills, go to CCHI directly: the current testing schedule is published on CCHI's scheduling page, and application and exam fees are listed on its Fees page. Verify any logistics detail against those official sources rather than a secondary summary, including this one. When you want scored practice against the exam's structure, the free practice materials for this exam are a natural next stop, and the broader study guide collection covers related credentials and languages.
- Record and self-score practice responses on lexical accuracy, grammar, and speech quality.
- Practice all four modes weekly, with consecutive dialogs getting the most time.
- Rehearse forward-only conditions: no re-recording and no replaying your own responses mid-session.
- Confirm current testing windows and fees on CCHI's official pages before booking.
