BEI Study Guide
A complete, practical guide to preparing for and passing the Board for Evaluation of Interpreters (BEI) exams: the written Test of English Proficiency (TEP) and the interpreter performance test. It explains what each exam measures, how raters score you, and a week-by-week plan to build the skills the test rewards.
Built from the official BEI Study Guide for General Interpreter Certification Candidates, Texas HHS testing resources, and established interpreter-education research. For certification rules, fees, eligibility, and renewal, this guide links to the Complete Texas BEI Certification Guide rather than repeating them.

Why this guide exists
The official BEI materials tell you the format of each exam, but they intentionally do not teach you how to prepare. This guide fills that gap: it turns the published test structure and scoring criteria into a concrete preparation method, so you know what to study, how to practice, and how to think the way a rater does. It is a study companion, not a certification reference; for the rules that govern certification, it points you to the Complete Texas BEI Certification Guide.
Who this guide is for
Before you begin
This guide assumes you already have a working foundation in both languages and the culture. If you are still building that foundation, start there first, because the exam is designed to detect it. Before you invest in a testing plan, you should have:
- Conversational ASL proficiency — you can hold real, two-way conversations with Deaf signers, not just produce vocabulary.
- Strong English skills — formal reading, vocabulary, and grammar at the level the written TEP expects.
- Familiarity with Deaf culture — lived exposure to the community, its norms, and its regional and generational variation.
None of these are the same as certification eligibility. For the formal prerequisites, education requirements, and who may sit for each exam, see the Complete Texas BEI Certification Guide.
Quick facts
- Two exams, in order. The written TEP first, then a performance test. Full rules and fees are in the Certification Guide.
- The TEP. 80 multiple-choice questions in 75 minutes; you pass by answering at least 55 correctly.
- The performance test. Expressive, receptive, and sight-translation tasks, recorded and scored by a team of trained raters.
- Levels differ by speed and complexity. Source material runs about 110 words per minute at Basic, 120 at Advanced, and 130 at Master.
- Meaning is scored first. Raters look for accurate meaning, then delivery, adaptability, and fluency.
- Prepare to test once. If you do not pass, there is a six-month wait before you can retake, so it pays to be ready.

How to use this guide
Read it start to finish the first time, then return to the parts you need. If you still need the written TEP, begin there. If you are preparing a performance test, focus on Scoring, Build Skills, and the study plan. Working interpreters leveling up can skim the format sections and go straight to Build Skills and Pitfalls. Short on time? The study plan and practice tools are the fastest path to a routine. Use the menu above to jump between sections at any point.
What the BEI exams actually measure
Effective preparation starts with understanding the construct behind the test, not just its format. BEI certification is a two-part process: a written English exam (the TEP) that gates everything, followed by a performance test that assesses your ability to interpret in realistic settings. Who is eligible, what it costs, and how to apply are covered in the Certification Guide; this section focuses on what the exams are trying to detect so you can aim your study at it.
Where the BEI is offered
The BEI system is owned and maintained by Texas Health and Human Services, and several other states license it for their own interpreter credentialing. BEI testing is currently offered in Texas, Illinois, Michigan, Missouri, and Wisconsin, and the exam structure, modes, and scoring criteria are the same wherever you sit for it — which is why the preparation in this guide applies in every one of them. Application steps, eligibility, fees, and continuing-education requirements are set by each state individually, so confirm those with the agency in the state where you plan to test. Texas rules are covered in the Complete Texas BEI Certification Guide.
The single criterion behind everything: meaning
The performance test is built around one core idea. You are asked to render the source message into the target language without distorting or omitting any part of its meaning, conserving tone, register, and intent rather than translating word for word. Nearly every scoring decision traces back to this. If your study is organized around conserving meaning, you are studying the right thing.
The abilities the job analysis identified
The test was designed from an empirical study of what Texas interpreters actually do. That analysis identified the cognitive abilities a certified interpreter must have, and those abilities are, in effect, your study targets:
- Working memory — holding concepts, words, and numbers while you process and produce.
- Selective, auditory, and visual attention — staying locked on one source amid distraction.
- Self-monitoring — catching and repairing your own errors during and after a rendition.
- Time-sharing — shifting efficiently between listening, analyzing, and producing at once.
- Information ordering and pattern inference — tracking sequence and filling gaps when input is incomplete.
- Mental stamina — sustaining heavy processing without breaking down for the length of a scenario.
The official guide is a map, not a course
The BEI Study Guide is explicit that it familiarizes you with format and criteria but does not provide instruction. Passing comes from language proficiency and interpreting practice built over time, which is what the rest of this guide is designed to help you develop.
Preparing for the TEP (written English test)
The Test of English Proficiency measures formal written English at roughly a high-school-graduate level. It is 80 multiple-choice questions across five equally weighted parts, with a strict 75-minute limit; you pass by answering at least 55 correctly. The time pressure is deliberate, meant to mirror real-world language demands, so pacing is part of the challenge.
| Part | What it tests | How to prepare |
|---|---|---|
| Reading Comprehension | Main idea, detail, implication, tone, and author stance across unfamiliar passages. | Read widely and analytically; practice separating main ideas from support and reading the question before hunting for the answer. |
| Synonyms | Precise vocabulary and shades of meaning among close choices. | Build vocabulary daily; learn roots, prefixes, and suffixes; note fine distinctions between near-synonyms. |
| Grammar & Usage | Idiomatic expressions and standard written English. | Study common idioms in context; review sentence-level grammar and standard usage rules. |
| Sentence Completion | Choosing words that complete a sentence for logic and style, including two-blank items. | Watch for logic signals like "but" and "also"; make sure both halves of a two-blank answer fit. |
| Antonyms | Word meaning and reasoning to the opposite of a term. | Drill opposites; when stuck, check answer choices for alternate meanings of the target word. |

The most efficient TEP prep
HHS itself recommends vocabulary building and SAT/GRE-style preparation. The official study guide also includes a full sample TEP with an answer key. Take that sample under a real 75-minute clock, score it honestly, and let your weak part decide where you spend the next week.
Do not underestimate the TEP
The TEP gates the entire process, and there is no appeal for a one-point miss and no exemption for having passed another organization's written exam. Candidates with strong signing skills sometimes stall here purely on English vocabulary. Treat it as a real exam, not a formality.
Cost, application, scheduling, and the retake window are certification rules; see the Certification Guide for those.
Preparing for the performance test
After you pass the TEP, you take the performance test for the level you are pursuing. Every level tests the same handful of task types, called modes; the levels differ mainly in speed, language complexity, and setting.
The modes, in plain terms
- Expressive interpreting — watch and hear spoken English and render it into ASL.
- Expressive transliterating — render spoken English into signed English (English structure and mouthing, with ASL features like use of space and classifiers where they aid meaning).
- Receptive — watch signed source and voice it into spoken English. At Advanced and Master this splits into receptive interpreting (from ASL) and receptive transliterating (from signed English).
- Sight translation — read a short written English document and render it into ASL for a monolingual ASL user.
How the levels differ
| Level | Parts | Source speed | Typical settings |
|---|---|---|---|
| Basic | 4 (receptive combined) | ~110 wpm | Routine K–12 educational and social-service language. |
| Advanced | 5 (receptive split) | ~120 wpm | Routine high-stakes: medical, social service, higher education, mental health, quasi-legal. |
| Master | 5 (receptive split) | ~130 wpm | Complex high-stakes: complex medical, mental-health, quasi-legal, and educational language. |

The mechanics of a part
Each part opens with an introduction that names the setting and audience, followed by an unscored warm-up you may watch or interpret, then a one-minute pause to prepare, then the cue to begin. The session is recorded and cannot be stopped, rewound, or replayed, though you may pause briefly between parts. Sight translation works differently: you get the document, roughly seven minutes total, and should review it before you begin, starting within two minutes.
Use the setup, don't waste it
The introduction and one-minute pause exist to help you. Use them to fix the setting, the speakers, the topic, and the register in your mind before the source starts. Walking in with the context already framed buys you processing time on the first, hardest lines.
Application, fees, and the entry points that let some candidates start above Basic are certification rules; see the Certification Guide.
How you're scored — and how to study for it
A team of trained raters scores each performance in two complementary ways: objectively and holistically. Understanding both lets you practice the way you will be judged.
Objective scoring: the units of meaning
Woven through every part are objective scoring units: specific words, phrases, and clauses judged critical to the message. They include specialized terminology, register, rhetorical features, general vocabulary, grammar, and culturally appropriate discourse, along with ASL-specific features such as classifiers and non-manual markers. The basic test is meaning: did your rendition communicate the full intent of that unit? Raters are trained to accept legitimate variation as long as the meaning lands.
Holistic scoring: the four dimensions
| Dimension | What it means | How to practice it |
|---|---|---|
| Interpreting Proficiency | Accurate, culturally appropriate transfer of meaning (scored through the objective units). | Work for meaning, not words; check renditions against source for omissions, additions, and distortions. |
| Delivery | Steady pacing, coherence, and composure across the whole scenario. | Practice full-length pieces without stopping; rehearse recovering smoothly after a stumble. |
| Adaptability | Resourcefulness when the text throws a curve, a shift in topic, tone, or difficulty. | Interpret varied, unfamiliar material; build strategies for unknown terms and fast passages. |
| Pronunciation & Fluency | Clear spoken English (rhythm, stress, intonation) and native-like signing with minimal hesitation. | Record and review voicing for clarity; drill fingerspelling, numbers, and sign fluency. |

The instruction that decides most scores
Conserve the message. Keep the speaker's register and tone, stay in first person when the source is in first person, carry colloquialisms across rather than formalizing them, and never "clean up" or omit. A polished rendition that quietly drops or upgrades content scores worse than a plainer one that keeps everything.
Building the skills the test rewards
This is where preparation is won. The exam does not reward memorization; it rewards a trained process. The techniques below come from mainstream interpreter education and map directly onto the scoring criteria above.
Interpret from meaning, using a process model
The field's cognitive models — Colonomos, Cokely, Gish, and Gile — all describe interpreting as comprehend, analyze, then reconstruct, not a direct swap of words. Two are especially useful in practice. Gish's goal-to-detail approach has you map a text's overall goal, themes, and supporting details before you render it, so you interpret ideas rather than strings of words. Gile's Effort Models frame interpreting as juggling listening, memory, production, and coordination under limited capacity, which explains why overloading one effort (say, chasing a hard term) makes the others fail.
Practice consecutive before simultaneous
Consecutive interpreting — taking in a full chunk, then rendering it — forces deep comprehension and complete messages, and it is widely used to build the analysis skills that simultaneous work depends on. Start consecutive with short segments, grow the segments as your memory improves, and only then move to simultaneous at your target level's speed.
Train memory, attention, and self-monitoring
Working memory and attention are trainable. Practice chunking information, restating a passage's meaning from memory before interpreting it, and interpreting through mild distraction to build focus. Research on interpreter training points to inhibition and executive-function control as key, so drills that force you to hold one thread while suppressing others pay off directly on test day.
Drill the ASL features raters watch
Because classifiers and non-manual markers are named scoring features, target them deliberately, along with use of space, depiction, register shifting, and the perennial weak spots: fingerspelling production and closure, and numbers. For hearing candidates, the receptive task (voicing ASL into English) is often the hardest part; the fix is volume and variety of authentic input, watching many different Deaf signers, including regional and heritage variation, until comprehension becomes automatic.
Close the loop: record, compare, target
The single most productive habit is disciplined self-analysis. Record every practice rendition, then compare it against the source for meaning, omissions, additions, and error patterns, and let those patterns choose your next drill. Tools like GoReact or even a phone camera make this routine; a study partner or mentor accelerates it.
Analyze
Map the source's goal, themes, and details before rendering.
Render
Interpret consecutively, then simultaneously at target speed.
Review
Record and compare to source for meaning and error patterns.
Target
Drill the specific weakness the review exposed, then repeat.
Language proficiency comes before test prep
No amount of test-taking strategy substitutes for fluent ASL and strong English. If your base language skills are still developing, the highest-value "study" is immersion and coursework: time in the Deaf community and structured interpreter education build the proficiency the test is designed to detect.
A 12-week study plan
This is a framework, not a rule. Adjust the length to your starting point, and if a diagnostic mock shows you are not ready, extend rather than test early. Run TEP prep and performance prep in parallel if you still need the written exam; if you already passed the TEP, put that time into interpreting practice.
Weeks 1–2
Record a full mock in every mode and score it against the four dimensions. Take the official sample TEP timed. Name your two biggest gaps.
Weeks 3–8
Consecutive first, then simultaneous at target speed. Daily receptive/voicing and fingerspelling/number drills. Daily TEP vocabulary. Weekly recorded self-review.
Weeks 9–12
Register and setting-specific vocabulary for your level. Full timed mocks under test conditions, no do-overs. Taper, rest, and confirm logistics.
A repeatable weekly cadence
- Source analysis. Map two or three texts (goal, themes, details) before interpreting them.
- Consecutive reps. Build memory with growing segment lengths.
- Simultaneous at speed. Match your level's source pace (about 110/120/130 wpm).
- Receptive/voicing. Voice varied Deaf signers into clear, well-paced English.
- Micro-drills. Fingerspelling closure and numbers, a few minutes daily.
- Recorded self-review. Compare to source; log error patterns; pick next week's target.
- Community contact. Real interaction with Deaf signers, not just recordings.
- TEP block (if still needed). Vocabulary plus one timed section.
Simulate early and often
The test is recorded, timed, and offers no second takes. Make at least your final weeks look exactly like that: one recording, one attempt, full length, no pausing to restart. The gap between practice-with-do-overs and one-take performance is where a lot of otherwise-ready candidates lose points.
Test-day execution
Preparation gets you to the door; execution gets you through it. A few habits protect the score you have earned.
TEP day
- Bring photo ID, two number-two pencils, and your confirmation letter; arrive early, as sites require.
- Pace for 75 minutes across 80 items, roughly a minute each; do not sink five minutes into one question.
- Answer everything. Unanswered items are counted wrong, so make an educated guess before time runs out.
- If you marked answers in the booklet, leave time to transfer them to the answer sheet; no extra time is given.
Performance day
- Arrive early with ID and confirmation; electronics and bags stay out of the room. The session is recorded.
- Use each introduction, warm-up, and one-minute pause to set context and register before you begin.
- Keep pace. If a word or phrase escapes you, let it go and stay with the source, then recover, rather than stalling.
- Pause only between parts. For sight translation, read the whole document first, then deliver.
Falling behind is how meaning gets lost
The official guidance is blunt: if you get stuck and fall behind, you will start omitting language you could otherwise have rendered. Protect your pace. A steady, complete rendition beats a perfect-but-truncated one.
Exact arrival windows, required documents, and results timelines are certification logistics; see the Certification Guide.
Common reasons candidates don't pass
Most failures cluster around a short list of avoidable patterns. Study this section as a pre-flight checklist.
Interpreting words instead of meaning
Word-for-word renderings, or ASL that follows English word order, break down under the objective scoring units. Map meaning first, then produce.
Producing the wrong target language
Expressive interpreting calls for ASL; expressive transliterating calls for signed English. Mixing them, or voicing that flattens ASL grammar, costs points. Know which target each part requires.
Weak receptive (voicing) skills
Many hearing candidates are stronger expressively than receptively. Guessing at unclear signs and losing meaning during voicing is a frequent failure point; fix it with wide, varied exposure to Deaf signers.
Flattening register and tone
Upgrading casual language to formal, or dropping affect, distorts the message. Match the source's register, keep first person, and carry tone across.
Testing before you're ready
Because a failed test means a six-month wait and a new fee, testing on hope is expensive. Let a full, honest mock, not a deadline, tell you when to sit.
Practicing with do-overs
If every practice rep allows a restart, you never rehearse the one-take, recorded reality of the exam. Simulate the real conditions well before test day.
Practice tools and the Deaf community
The best preparation blends official materials, structured self-recording, and real time with Deaf people. No single tool is enough on its own.
Start with the official materials
Work directly from the BEI Study Guide: it lays out every part's format, includes a sample TEP with an answer key, shows sample performance scenarios, and explains the rating criteria your renditions will be measured against. HHS also publishes a short list of books and websites it has found helpful. Anchor your prep here, then build outward.
Record, mock, and get feedback
Use a self-recording platform such as GoReact, or simply a phone, to capture and review every rendition. Where you can, take a mock exam scored by an experienced interpreter or mentor; outside feedback catches patterns you cannot see in your own work.
Ground it in theory and ethics
The Registry of Interpreters for the Deaf (RID) publishes the NAD-RID Code of Professional Conduct and professional-development resources; national interpreter-education projects offer free modules and mentoring materials built around the Cokely and Colonomos process models. Reading widely, on the models above and on discourse analysis, sharpens the judgment the test rewards.
Immerse in the community
Authentic input is irreplaceable. Attend Deaf events, take Deaf-led ASL classes, follow Deaf creators and vlogs, and build genuine relationships. Exposure to many signers, registers, and regional varieties is the surest route to strong receptive skills and culturally accurate interpreting.
Match your practice to your target level
Practice at the speed and setting you will be tested on: around 110 wpm and educational/social-service topics for Basic, 120 wpm and routine high-stakes for Advanced, 130 wpm and complex high-stakes for Master. Building specialized vocabulary for those settings is part of the work.
Study FAQ
Preparation questions. For certification rules, each item points to the Certification Guide.
How long should I study?
- It depends on your starting proficiency. The 12-week framework is a guide; extend it if a diagnostic mock says you are not ready.
- Language fluency comes before test prep. If your ASL or English base is still developing, budget months, not weeks.
Which exam do I take first?
- The written TEP first; passing it makes you eligible to apply for a performance test. See TEP Prep and Performance.
Can I use this guide if I'm testing outside Texas?
- Yes. BEI testing is offered in Texas, Illinois, Michigan, Missouri, and Wisconsin, and the exam structure, modes, and scoring criteria are the same in each.
- Application steps, eligibility, fees, and continuing-education requirements are set state by state, so confirm those with the agency where you plan to test.
Which level should I attempt?
- New candidates generally begin at Basic; some already-certified interpreters may start higher. Eligibility and entry points are in the Certification Guide.
- Prepare for the speed and settings of the level you choose (see Performance).
Do I need an interpreter training program?
- Structured education is strongly recommended for building proficiency, though program and degree requirements are a certification matter, see the Certification Guide.
How is the performance test scored?
- Objectively (meaning-based scoring units) and holistically across four dimensions. See Scoring.
My receptive (voicing) skills are weak. What helps most?
- Volume and variety of authentic input: many different Deaf signers, regional and heritage variation, plus recorded voicing practice reviewed against the source. See Build Skills.
How should I prepare for the TEP specifically?
- Vocabulary building and SAT/GRE-style prep, plus the official sample TEP taken under time. See TEP Prep.
What if I don't pass?
- There is a waiting period before you can retake, so prepare to test once. Reapplication rules and timing are in the Certification Guide.
- Use any feedback to target specific weaknesses, then re-run the record-compare-target loop.
Fees, applications, renewal, and CEUs?
- All certification rules, covered in the Complete Texas BEI Certification Guide.
