What the Letters Actually Stand For
"TExES" is the umbrella name for Texas Examinations of Educator Standards, the state's certification testing system administered under Texas Education Agency and State Board for Educator Certification (SBEC) authority. "STR" is shorthand for Science of Teaching Reading, and the full official title is TExES Science of Teaching Reading (293). The number 293 is the specific test code Pearson and TEA use to identify this exact assessment among dozens of other TExES certification tests.
That numeric suffix matters more than it looks. Several credentials in other states use similar acronyms for entirely different tests, so if you see "STR" attached to unfamiliar fees, domain weights, or pass rates elsewhere, it is not describing this Texas exam. Every fact on this page refers strictly to TExES 293.
Why Texas Created This Exam
Texas built the Science of Teaching Reading exam to make sure certified teachers understand how reading skills actually develop in the brain and classroom - not just literacy theory in the abstract. The name signals intent: this is a science-based test, grounded in how students decode text, build vocabulary, and construct meaning, rather than a general "reading methods" survey.
Passing STR is tied to specific certification routes. It supports designated Texas PK-6 and 4-8 certification pathways, meaning candidates pursuing those grade bands need to clear this exam as part of becoming fully certified. Once certified, a standard Texas classroom-teacher certificate remains valid for five years and renews with 150 continuing professional education (CPE) hours - a detail worth knowing as you plan your longer-term certification timeline, not just exam day.
How the Name Translates Into Exam Format
Because the exam is framed around the "science" of reading instruction, its format is built to test applied knowledge rather than simple recall. Candidates sit for 90 selected-response questions plus one constructed-response question. The full appointment runs 4 hours and 45 minutes of actual testing time within a 5-hour window, giving you a buffer for check-in and breaks.
The test is fully computer-administered at Pearson VUE test centers, and it includes a headset for one listening-based item - a detail that surprises some first-time test-takers who expect a purely text-based reading exam. You may also encounter unscored field-test questions mixed in, which is standard practice for many certification exams and not something to worry over; you cannot identify them during testing.
Key Takeaway
Treat the listening item and mixed field-test questions as normal exam mechanics - focus your energy on content mastery, not trying to spot which questions "count."
For a deeper breakdown of how these question types map to content, see the TExES STR Exam Domains 2026: Complete Guide to All 4 Content Areas.
The Four Domains Behind "Science of Teaching Reading"
The exam's content framework is organized into four domains, and their weighting tells you exactly where the "science" emphasis lives.
Domain 1: Reading Pedagogy (13%)
Covers instructional planning, assessment use, and how teachers structure reading instruction across a classroom of varied learners.
- Differentiated instruction strategies
- Using assessment data to guide lesson planning
Domain 2: Reading Development: Foundational Skills (43%)
The largest domain by far, covering phonological awareness, phonics, decoding, and how word-recognition skills develop in young readers.
- Phonemic and phonological awareness progression
- Systematic, explicit phonics instruction
- Fluency development and its link to comprehension
Domain 3: Reading Development: Comprehension (24%)
Focuses on vocabulary growth, text comprehension strategies, and how meaning-making builds on foundational skills.
- Vocabulary instruction across content areas
- Comprehension strategies for narrative and informational text
Domain 4: Analysis and Response (20%)
Tests your ability to analyze student reading behaviors, interpret data, and respond with appropriate instructional moves.
- Analyzing running records and error patterns
- Designing intervention responses to specific reading difficulties
Notice that Domain 2 alone accounts for nearly half the exam. This single weighting fact should shape your entire prep plan - spending equal time across all four domains would be a mistake given how the test is actually built. For domain-by-domain study strategies, the TExES STR Study Guide 2026: How to Pass on Your First Attempt walks through allocation in more depth.
| Domain | Weight | Core Focus |
|---|---|---|
| Reading Pedagogy | 13% | Instructional planning & assessment use |
| Reading Development: Foundational Skills | 43% | Phonics, phonological awareness, decoding |
| Reading Development: Comprehension | 24% | Vocabulary & meaning-making |
| Analysis and Response | 20% | Interpreting data, planning interventions |
Who Actually Takes the TExES STR
Candidates pursuing Texas PK-6 and 4-8 certification routes take this exam as part of their path to a standard classroom-teacher certificate. That includes traditional teacher-prep program graduates, alternative certification candidates, and educators adding certain certifications to an existing credential where STR is a required test.
Because the exam name centers on the "science" of reading, districts and hiring committees increasingly treat passing scores as a signal of strong foundational-literacy instruction skills - not just a box to check.

Registration, Fee, and Eligibility Basics
The TExES STR is administered by Pearson Evaluation Systems at Pearson VUE test centers, with a $136 exam fee. Before you can schedule a seat, you need state approval to test - typically granted once your certification program or educator preparation entity confirms you meet requirements. This approval step trips up some first-time candidates who assume they can register the moment they decide to take the exam.
To pass, you need a scaled score of 240. The 2024-2025 statewide best-attempt pass rate was 92%, which suggests most well-prepared candidates clear the bar - but that figure covers all attempts statewide, not a guarantee for any individual test-taker who under-prepares for Domain 2's density.

Preparing Around the Name, Not Just the Number
Once you understand that "Science of Teaching Reading" means the exam prioritizes foundational-skills instruction above everything else, your prep schedule should reflect that hierarchy directly.
Foundational Skills Deep Dive
- Phonological awareness sequencing
- Systematic phonics instruction methods
- Decoding and fluency connections
Comprehension & Vocabulary
- Text comprehension strategies
- Vocabulary instruction across genres
Pedagogy, Analysis & Response
- Assessment-driven instructional planning
- Interpreting student reading data
- Full-length timed practice under 5-hour conditions
This isn't a generic study calendar - it's ordered specifically because Domain 2 carries 43% of the exam and deserves the most runway, while pedagogy and analysis items build naturally once foundational-skills knowledge is solid. Practicing full-length questions in test-like conditions on our practice test platform before exam day helps you calibrate pacing across all 90 selected-response items plus the constructed-response prompt.
