What Is TExES STR?

What Is TExES STR? An Overview

TExES STR stands for the TExES Science of Teaching Reading (293), a certification exam required for certain Texas educator certification routes. It is developed and administered under the authority of the Texas Education Agency (TEA) and the State Board for Educator Certification (SBEC). The exam measures whether a prospective teacher understands how children learn to read, how reading difficulties develop, and how to deliver evidence-based reading instruction in a Texas classroom.

This is not a generic literacy quiz. It is a focused, standards-aligned assessment built around a specific four-domain framework that Texas has adopted to make sure every certified teacher in reading-dependent roles can teach foundational skills, comprehension, and analytical reading with fidelity. If you're searching for background on the credential itself, our TExES STR Certification overview and the companion piece on What Is TExES STR Certification? go deeper into how the credential fits into the broader Texas certification system.

Who Administers It and How the Test Works

TExES STR is administered by Pearson Evaluation Systems at official Pearson VUE test centers. Candidates schedule a computer-based testing appointment that runs 5 hours total, with 4 hours and 45 minutes allotted for actual testing time. The remainder covers check-in, instructions, and administrative steps at the center.

The exam fee is $136, and candidates must have state approval to test before they can register - meaning your Educator Preparation Program (EPP) or the relevant certification pathway must clear you first. This is a detail many first-time test-takers overlook, and it's worth mapping out timing before you commit to a testing window. For a full breakdown of registration mechanics, eligibility rules, and prerequisite steps, see TExES STR Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Because the exam is computer-administered, you'll interact with an on-screen interface rather than a paper booklet. One listening-based item requires a headset, which is provided at the test center - this is a small but notable feature of the format that catches some candidates off guard if they haven't reviewed the test-day logistics in advance.

The Four Domains Explained

TExES STR is structured around four content domains, each weighted differently on the exam. Understanding these weights is the single most important strategic input for your study plan.

Since Domain 2 alone accounts for 43% of the exam, it deserves a disproportionate share of your study hours. For an in-depth walkthrough of every competency and skill statement inside each domain, read our TExES STR Exam Domains 2026: Complete Guide to All 4 Content Areas.

Question Format and Testing Experience

The exam contains 90 selected-response questions plus one constructed-response question. Selected-response items typically present a classroom scenario, student work sample, or assessment data point and ask you to identify the best instructional response. The single constructed-response question requires a written answer, usually asking you to analyze a reading behavior or design an instructional response grounded in the science of reading.

Because the test may also include unscored field-test questions mixed in among the scored items, you won't be able to tell which questions count toward your score. Treat every item with equal seriousness rather than trying to guess which ones are "real."

If you want a realistic sense of how difficult the exam actually feels once you account for pacing, question density, and the weight of Domain 2, our detailed breakdown in How Hard Is the TExES STR Exam? Complete Difficulty Guide 2026 unpacks this from multiple angles.

Passing Score and What It Means

To pass TExES STR, candidates must earn a scaled score of 240. Scaled scores are not raw percentages - they're calculated using a standardized formula that accounts for question difficulty, so 240 doesn't map cleanly to "240 out of 300" or similar simple math. What matters practically is that you need strong performance across all four domains, with special attention to Domain 2 given its outsized share of the test.

Statewide data for 2024-2025 shows a best-attempt pass rate of 92%, which suggests that well-prepared candidates clear the bar at a high rate. That said, a strong pass rate doesn't mean the content is easy - it likely reflects that most candidates entering the test have already been through structured reading-instruction coursework. For the full context behind that number and how it's calculated, see TExES STR Pass Rate 2026: What the Data Shows, and for a granular look at how the scaled score system works, read TExES STR Passing Score 2026: Exactly What You Need to Pass.

Who Needs to Pass TExES STR

TExES STR passage supports specified Texas PK-6 and 4-8 certification routes. In practical terms, this means teachers pursuing early childhood, elementary, and certain middle-grades certifications in Texas need to clear this exam as part of their path to a standard classroom-teacher certificate. Texas standard classroom-teacher certificates are valid for five years and renew through 150 hours of continuing professional education (CPE), so this exam is one checkpoint in a longer professional trajectory rather than a one-time hurdle.

School districts, charter networks, and reading-intervention programs across Texas look for candidates who hold this credential because it signals grounding in structured literacy and the science of reading - an area of increasing scrutiny in Texas classrooms.

How to Prepare Strategically

Given the domain weights, your study time should not be split evenly across four domains. Domain 2 (Foundational Skills) at 43% deserves roughly triple the attention of Domain 1 (Reading Pedagogy) at 13%. A simple way to think about allocation: treat the exam blueprint itself as your syllabus.

Spacing your review this way lets you spend the most hours on the highest-weighted domain early, then circle back for spaced review before test day. For a complete week-by-week study framework built specifically around this domain structure, see our TExES STR Study Guide 2026: How to Pass on Your First Attempt. If you just need a compact reference for last-minute review, the TExES STR Cheat Sheet 2026: One-Page Review of Must-Know Facts condenses the must-know facts into one page.

Practicing with realistic, scenario-based questions matters more than memorizing definitions in isolation, since the exam presents classroom situations rather than asking you to define terms directly. Working through full-length timed simulations on our practice test platform before test day helps you get comfortable with the pacing demands of 90 selected-response items plus a constructed-response task.

What Happens After You Pass

Passing TExES STR is one component of completing your certification requirements for the applicable PK-6 or 4-8 route. Once you've met all requirements for your certification area, your standard classroom-teacher certificate becomes valid for five years. Maintaining it requires 150 hours of continuing professional education (CPE) across that period, which is a normal part of a Texas teaching career rather than something unique to reading-focused roles.

Because this exam certifies knowledge of the science of reading specifically, holding it can also open doors to reading-specialist or intervention-coordinator responsibilities within a school, depending on your district's staffing structure and additional credentials. If you want a broader picture of the certification landscape and how this exam fits into it, revisit TExES STR Certification for a full walkthrough.

For candidates still deciding whether to start this process, running a diagnostic practice session on TExES STR Exam Prep is a low-effort way to see how your current knowledge maps against the four domains before you commit to a study schedule or testing date.
