The TEA STR exam — formally known as the TExES Science of Teaching Reading (STR) 293 — is one of the most important certification tests Texas teachers must pass before entering an elementary or early childhood classroom. Administered by the Texas Education Agency and developed by Pearson, this examination measures whether candidates understand the research-backed, structured literacy practices that lead to strong reading outcomes for all students, including those with dyslexia and other reading difficulties.

If you are preparing for this test, this guide covers every domain, the exact exam format, proven study strategies, and a curated set of free practice resources to help you pass on your first attempt.
Understanding why the TEA created this exam requires a brief look at Texas literacy policy. In 2019, the Texas Legislature passed House Bill 3 and Senate Bill 11, collectively mandating that all teachers of kindergarten through third grade — and all reading specialists — demonstrate deep knowledge of the science of reading before receiving or renewing their certificates.
The STR exam operationalizes that mandate by testing five tightly defined competency domains that span phonological and phonemic awareness, word analysis, fluency, vocabulary, and comprehension, along with literacy assessment and instructional planning grounded in the Simple View of Reading and Scarborough's Reading Rope.
Many teacher candidates underestimate the STR exam simply because it covers content they assume they already know. In practice, however, the test goes well beyond surface-level reading instruction. Questions probe the neuroscientific basis of word recognition, the developmental sequence of phonological awareness skills, the specific grapheme-phoneme correspondences that English orthography follows, and the evidence base behind structured literacy approaches. A candidate who has taught reading for years can still struggle if their coursework leaned toward whole-language or balanced-literacy frameworks, because the STR aligns firmly with the converging body of cognitive and linguistic science.
One of the most practical things you can do early in your preparation is take a full-length diagnostic test under timed conditions. This reveals which of the five STR domains need the most attention and prevents the common mistake of spending too much study time on strengths rather than weaknesses. After scoring your diagnostic, map each missed question to a specific competency standard published in the TExES STR Preparation Manual, available free from the TEA website. This standard-by-standard gap analysis is far more efficient than reading an entire textbook from cover to cover.
Cost and scheduling logistics matter too. The STR 293 exam costs $116 to register, and you can schedule it at any Pearson VUE testing center across Texas or opt for online proctored delivery from your home or office. Testing windows are open year-round, so you have flexibility, but you should still plan your registration date strategically — aim to complete your primary coursework in literacy before scheduling, because many of the most challenging questions require you to apply theoretical knowledge to realistic classroom scenarios rather than simply recall definitions.
This guide is structured as a complete certification prep hub. You will find domain breakdowns, an exam-format table, a recommended study schedule, a checklist of must-do preparation tasks, and links to free practice quizzes organized by STR competency. Whether you are taking the test for the first time or retaking after an unsuccessful attempt, the information here will help you build a targeted, efficient, and confident preparation plan.

Finally, keep in mind that passing the STR is not just about getting a certificate — it is about becoming the kind of teacher whose students actually learn to read. Texas has made a significant investment in restructuring literacy education based on decades of converging evidence from cognitive science, linguistics, and special education research. The STR exam ensures that every teacher entering a Texas classroom carries that knowledge with them on day one, and the students they serve will be better readers because of it.
Domain I covers phonological and phonemic awareness — the ability to hear, identify, and manipulate the sound structures of spoken language entirely without print. Questions in this domain test your knowledge of the developmental continuum: children typically master word awareness and rhyme detection before they can segment syllables, and syllable segmentation before they can isolate and manipulate individual phonemes. The STR exam will present scenarios involving specific student errors and ask you to identify the most appropriate next instructional step, which requires you to know exactly where each sub-skill falls on the developmental ladder.
Domain II is the largest procedural domain and covers the full scope of word analysis, including systematic synthetic phonics, the six syllable types of English (closed, open, vowel team, vowel-consonant-e, r-controlled, and consonant-le), common morphological patterns such as prefixes, suffixes, and Latin and Greek roots, and the role of orthographic mapping in sight-word acquisition.
Many candidates find this domain the most content-heavy, because English orthography is a deep alphabetic system whose patterns are extensive and rule-governed in ways that whole-language training often does not emphasize. Expect questions that ask you to sequence phonics instruction, identify the phoneme-grapheme correspondences in a target word, or select the most appropriate decodable text for a student at a given instructional level.
Domain III focuses on reading fluency, which the National Reading Panel defined as the bridge between decoding and comprehension. The STR exam tests your understanding of the three components of fluency — accuracy, automaticity, and prosody — and the instructional practices that develop each component. You should know the research on repeated reading, partner reading, reader's theater, and corrective feedback techniques. The exam also tests your ability to interpret fluency assessment data, including oral reading fluency (ORF) scores expressed in words correct per minute (WCPM), and to use those scores to set realistic instructional targets.
Domain IV addresses vocabulary and academic language development, which is closely tied to reading comprehension outcomes. Questions here require knowledge of the three-tier vocabulary framework: Tier 1 words are common everyday words, Tier 2 words are high-utility academic words that appear across subject areas, and Tier 3 words are domain-specific technical terms.
You will need to know explicit vocabulary instruction routines, including the Frayer Model and semantic mapping, as well as implicit vocabulary acquisition through wide reading. The domain also covers morphological instruction — teaching students to analyze prefixes, roots, and suffixes to infer word meaning — which has a strong evidence base for intermediate and upper elementary learners.
Domain V carries the highest weight at 31 percent and spans reading comprehension, text-structure knowledge, and literacy assessment. The comprehension portion tests your understanding of text-based inferencing, narrative versus informational text structures, and the role of background knowledge and language comprehension in the Simple View of Reading. The assessment portion requires you to distinguish among universal screening measures, diagnostic assessments, progress monitoring tools, and summative evaluations, and to match each type to its appropriate instructional purpose. Expect scenario-based items that present student data and ask you to interpret results and plan next steps.
Across all five domains, the STR exam uses a multiple-choice format in which three or four answer choices may look plausible to an underprepared candidate. The key to distinguishing correct answers from attractive distractors is grounding your reasoning in the evidence base rather than personal teaching experience. For example, a question about phonics instruction may include one choice reflecting a balanced-literacy approach that many practicing teachers use daily — but the STR credits only the structured-literacy, systematic, explicit approach supported by decades of cognitive science research. Knowing this testing philosophy will prevent many avoidable errors.
It is also worth noting that the exam includes constructed-response elements in some earlier versions, though the current STR 293 is entirely selected-response. Nevertheless, you should practice writing out explanations of why each wrong answer is wrong, not just why the correct answer is right. This deeper processing forces you to truly understand the tested concepts rather than recognize them superficially. Pairing active recall with retrieval practice — using flashcards, practice tests, and self-quizzing — has a far stronger evidence base for long-term retention than passive re-reading of notes or textbooks.
For Domains I and II, the most effective study strategy combines conceptual mapping with hands-on practice. Create a visual chart of the phonological awareness hierarchy — from large units like words and syllables down to individual phonemes — and use it to categorize every practice question you encounter. For word analysis, build a morpheme bank: list the 50 most common Latin and Greek roots along with three or four English words derived from each, so you can answer both direct knowledge questions and scenario-based items confidently.
Supplement your notes with structured phonics scope-and-sequence charts from programs like RAVE-O, Wilson Reading System, or Orton-Gillingham curricula. These published sequences align directly with what the TEA STR exam expects candidates to know about the order in which phonics patterns should be taught. Practice segmenting and blending words yourself using Elkonin sound boxes — the physical act of manipulating phonemes reinforces the metalinguistic awareness the exam tests and helps you answer student-scenario items with greater accuracy.
For Domain III, focus on memorizing the WCPM benchmark norms published by Hasbrouck and Tindal for grades one through eight, at the 25th, 50th, and 75th percentiles. The STR exam regularly presents student fluency data and asks whether a student is on grade level, and knowing these benchmarks precisely prevents guessing. Also study the prosody rubric used in ORF assessments, because questions often ask you to distinguish a student who reads accurately but lacks expression from one who needs rate-focused intervention.
For Domain IV vocabulary, memorize the three-tier framework and practice categorizing words on the fly — during your study sessions, pick a random paragraph and classify every content word as Tier 1, 2, or 3. Study explicit instruction routines like the Marzano six-step process and the Frayer Model in enough detail that you can evaluate their appropriate use in classroom scenarios. Pay special attention to morphological instruction research, because the STR exam frequently asks candidates to design vocabulary lessons that use root analysis as the central instructional move.
Domain V requires two parallel knowledge bases: one for comprehension theory and instruction, and one for literacy assessment literacy. For comprehension, study the Simple View of Reading equation (RC = D × LC), Scarborough's Reading Rope, and the text-structure categories for both narrative and informational texts. Know the difference between literal recall, inferential reasoning, and evaluative comprehension, and be able to identify which question type a given item stem is targeting — because the exam sometimes tests whether you can classify question types as part of a lesson-planning scenario.
For assessment, distinguish clearly among the four assessment purposes: universal screening identifies students at risk early in the year; diagnostic assessment pinpoints the specific skill deficits driving the risk; progress monitoring tracks whether intervention is working; and summative assessment evaluates mastery at the end of a unit or year. The STR exam often presents a student profile and asks which assessment type to use next. Getting these categories confused is one of the most common error patterns among candidates who miss passing by a small margin.
With a 31% weighting, Domain V (Comprehension and Literacy Assessment) is worth nearly a third of your total score. Candidates who score well in Domains I–IV but underperform in Domain V often miss passing by just a few points. Devote at least 35% of your total study time to comprehension theory, text structures, and the four assessment purposes before your test date.
The science of reading is the intellectual foundation of the entire STR exam, and candidates who understand it at a deep level find the test far more navigable than those who approach it as a collection of disconnected facts to memorize. At its core, the science of reading refers to a body of converging evidence accumulated over more than four decades from cognitive psychology, educational psychology, linguistics, neuroscience, and special education research. This evidence consistently shows that learning to read is not a natural developmental process like learning to speak — it requires explicit, systematic instruction in the alphabetic code.
The Simple View of Reading, proposed by Gough and Tunmer in 1986, is the single most important theoretical model for the STR exam. The formula RC = D × LC expresses reading comprehension (RC) as the product of decoding ability (D) and linguistic comprehension (LC). The multiplication sign is critical: if either factor is zero, reading comprehension is zero.
A student who can decode every word but understands nothing about the topic cannot comprehend the text. A student with excellent oral language comprehension but inadequate decoding is equally stymied. The model explains why both structured phonics instruction and rich language and knowledge building are necessary components of a complete literacy program.
Scarborough's Reading Rope, published in 2001, extends the Simple View by illustrating how multiple skill strands weave together over time to produce skilled, fluent reading. The word recognition strand includes phonological awareness, decoding, and sight recognition; the language comprehension strand includes background knowledge, vocabulary, language structures, verbal reasoning, and literacy knowledge. Early in development these strands are relatively loose and independent; as a student becomes a skilled reader, they become tightly interwoven and automatic. The STR exam uses the Reading Rope as an organizing framework for many of its scenario-based questions about student profiles and instructional needs.
Orthographic mapping, a concept developed by Linnea Ehri, explains the cognitive mechanism by which readers store words in long-term memory. When a reader encounters a new word, they connect its spelling to its pronunciation and meaning through a process that depends on phonemic awareness and phonics knowledge. Once a word is orthographically mapped, it can be recognized instantly and automatically — it becomes a sight word.
This research directly challenges the common misconception that sight words are learned by memorizing their visual shape rather than analyzing their sound-spelling patterns. The STR exam frequently tests whether candidates understand this mechanism and can select instructional practices that support it.
Structured literacy is the umbrella term for instructional approaches that implement the science of reading in the classroom. Structured literacy programs are explicit (skills are taught directly, not discovered), systematic (instruction follows a logical sequence from simple to complex), sequential (each new skill builds on previously mastered skills), cumulative (review is built into every lesson), and diagnostic (instruction is continuously adjusted based on ongoing assessment). The Orton-Gillingham approach is the most historically influential structured literacy framework, and programs like Wilson Reading System, SPIRE, and RAVE-O are all Orton-Gillingham-derived.
Knowing the defining characteristics of structured literacy will help you answer a large number of instructional-design questions correctly.
Dyslexia receives specific attention in the STR framework because Texas law requires all K–3 teachers to be able to identify early warning signs, understand the neurological basis of the condition, and provide or refer for appropriate intervention. Dyslexia is characterized by difficulty with accurate and fluent word recognition and poor spelling, resulting from a deficit in the phonological component of language.
It is not caused by low intelligence, poor vision, or inadequate motivation. The STR exam may ask candidates to distinguish dyslexia warning signs from typical reading development delays, or to select the most appropriate assessment for a student suspected of having dyslexia.
The role of background knowledge in reading comprehension has received increasing attention in reading research, particularly through the work of E.D. Hirsch and the knowledge-building curriculum movement. A landmark 1988 study by Recht and Leslie demonstrated that middle schoolers with high background knowledge about baseball understood a passage about a baseball game far better than high-skilled readers with low baseball knowledge — even when the high-skilled readers had objectively better reading ability.
This study has been replicated in multiple domains and directly informs why the STR exam expects teachers to build content-rich curriculum alongside skills instruction rather than treating reading as a context-free skill.
Test-day performance depends as much on exam strategy as on content knowledge, and candidates who have mastered the material can still underperform if they mismanage their time or fall into predictable question traps. The most important strategic skill for the STR exam is the ability to eliminate answer choices that reflect balanced-literacy or whole-language assumptions, because these distractors are deliberately included to catch candidates who rely on conventional classroom practice rather than research evidence. When you see a choice that involves cueing strategies, context guessing, or incidental phonics instruction, treat it as a red flag.
Time management within the three-hour window is straightforward if you maintain a pace of approximately 90 seconds per question. With 115 questions total (including unscored pilot items), you have a comfortable margin — about 20 minutes to review flagged items at the end. Use the built-in flagging tool in the Pearson VUE interface to mark questions you are uncertain about and return to them after completing the rest of the exam. Never leave a question blank; an educated guess always gives you a 25% or better chance, while an omitted item guarantees zero credit.
On scenario-based questions, which make up a substantial portion of the exam, read the question stem before reading the student vignette or data table. Knowing what you are looking for before you encounter the stimulus material prevents you from getting distracted by irrelevant details. After identifying the correct answer using your content knowledge, verify that it aligns with what an evidence-based, structured-literacy-trained teacher would do, not what an experienced classroom teacher might do based on intuition or convenience.
Arrive at the testing center at least 30 minutes early. Pearson VUE requires you to present two valid forms of identification, including one government-issued photo ID, and to complete a biometric check-in process that can take 10 to 15 minutes. Personal items, including phones, watches, wallets, and snacks, must be stored in a provided locker. You will be given a laminated notepad and marker for scratch work, so plan to use these for elimination notes, quick calculations, and jotting down remembered benchmark data like WCPM norms.
If you are testing online via remote proctoring, complete a full system check at least 48 hours before your appointment using the Pearson VUE system check tool. Ensure your room is completely clear of books, papers, and second monitors. The proctor will ask you to do a 360-degree camera sweep of your workspace before the exam begins, and any prohibited materials in view can result in an immediate dismissal and score cancellation. Use a wired internet connection rather than Wi-Fi if possible, because connection drops during a proctored session trigger a security review and can delay your score report.
After the exam, your unofficial score report appears on screen immediately at the testing center or within your Pearson VUE account for online test-takers. The scaled score range is 100 to 300, with 240 as the passing threshold. Scores below 240 include a diagnostic profile showing your performance in each domain, which is invaluable for targeted retake preparation. You must wait 30 days before retaking the exam, giving you enough time to address specific domain weaknesses with focused study rather than repeating the same preparation approach that did not work the first time.
Finally, remember that every hour you invest in preparing for the STR exam is an investment in your future students' reading outcomes. Research is unambiguous: students whose teachers have strong foundational knowledge of structured literacy and the science of reading make significantly faster progress, particularly students who are at risk for reading difficulties. Passing the TEA STR exam with deep understanding — not just minimum competency — positions you to be an exceptionally effective literacy teacher from the very first day you stand in front of a classroom.
Building an effective multi-week study plan is the single most important preparation decision you will make. Candidates who study in focused, spaced sessions consistently outperform those who cram intensively in the final week before the exam. The research on spaced repetition and interleaved practice is unambiguous: distributing study sessions across multiple weeks, mixing content from different domains within each session, and testing yourself frequently rather than re-reading notes all produce dramatically better long-term retention and test performance.
A practical eight-week plan begins with a diagnostic week in which you take a full-length practice test and analyze your domain scores. Weeks two and three should focus on Domains I and II, the phonological and word-analysis content, because this material is foundational — it underpins everything else on the exam, including comprehension and assessment questions that reference student decoding profiles. Spend each study session on no more than one or two competency standards, and end every session with a self-quiz of at least ten items covering the material you just reviewed.
Weeks four and five move to Domains III, IV, and V. Fluency and vocabulary content is relatively compact, so most candidates can cover both domains in two weeks if they study six to eight hours per week. Domain V — comprehension and assessment — is larger and more conceptually demanding, so allocate extra time to it within these two weeks and plan to revisit it again in week seven. Use practice quizzes organized by domain to track your improvement and identify any competency standards that remain below your target accuracy rate of at least 75 percent on practice items.
Week six is integration week: take a second full-length timed practice test under realistic conditions — no phone, no breaks longer than ten minutes, no looking at notes. Score the test and compare your domain profile to your week-one diagnostic. You should see meaningful improvement in the domains you studied first. Any domain still below 70% accuracy needs a dedicated review session in week seven. Make a short error log listing each missed item, the correct answer, and the specific reason you missed it — this log is your most valuable study tool for the final week.
Week seven is for targeted remediation based on your error log. Group your errors by competency standard, identify the two or three standards with the most misses, and do deep-dive study on just those standards using the TEA preparation manual and secondary sources like the International Dyslexia Association's Knowledge and Practice Standards. Do not try to review everything — strategic, targeted remediation is far more efficient than broad re-reading at this stage of preparation.
Week eight is light-touch review and logistics. Take one or two short practice quizzes per day to maintain retrieval practice without fatiguing yourself before the exam. Confirm your testing appointment, verify your ID requirements, and if testing online, run a final system check. The night before the exam, set out your ID and testing materials, get a full night of sleep, and eat a balanced breakfast the morning of the test. Cognitive performance declines measurably with sleep deprivation, and no amount of last-minute studying compensates for arriving at the testing center exhausted.
Throughout your preparation, use the free resources available on PracticeTestGeeks to supplement your domain study. The quizzes below are organized by STR competency so you can target exactly the skill area you need to strengthen. Each quiz provides immediate feedback and explanations that connect the correct answer to the research evidence underlying it — the same connections you will need to make independently when you sit down at the Pearson VUE terminal on exam day. Consistent, deliberate practice with these questions is one of the most efficient uses of your preparation time.
