TExES Science of Teaching Reading

The Science of Teaching Reading (STR) exam is a new requirement for all teacher candidates who seek certification in grades pre-kindergarten through Grade 6 (Pre-K-6). The purpose of the exam is to ensure candidates demonstrate proficiency in the science of teaching reading. The STR exam is an amendment to Texas Education Code (TEC) §21.048 (a-2), becoming effective January 1, 2021.


What is the “Science of Reading?”

The Science of Reading (SoR) is relatively new research (over the past 20 years) focusing on understanding the cognitive processes involved in successful reading acquisition. The research behind SoR is empirically supported, providing information on how individuals read, the skills involved with reading, how skills work together, and the parts of the brain responsible for reading development, leading to evidence-based best-practice approaches to teaching foundational literacy. SoR empowers educators to help students read by providing key approaches to instruction to reach all learners.

Who is required to take the STR exam?

Teacher candidates, probationary or intern teachers, and teachers looking to add one of the five certification fields to their standard certificate are now required to take the exam. The five certification fields requiring the STR exam include:

  • Early Childhood – Pre-K through Grade 3
  • Core Subjects with Science of Teaching Reading – Pre-K through Grade 6
  • Core Subjects with Science of Teaching Reading – Grades 4 through 8
  • English Language Arts and Reading with Science of Teaching Reading – Grades 4 through 8
  • English Language Arts and Reading/Social Studies with Science of Teaching Reading – Grades 4 through 8

Educators with standard certification in one of the above fields are not required to take the STR exam to renew their standard certificate.

STR Design

The Science of Reading exam is a computer-administered exam containing 90 selected-response questions and one constructed-response question. You have five hours to complete the exam, which includes 15 minutes for the exam tutorial. Content in the STR exam is organized into four domains. Competencies, which define each domain, examine your understanding and knowledge of the concepts, principles, and best practices using developmentally appropriate research- and evidenced-based assessments and instructional methods to promote student development.

Let’s take a look at the four domains.

Domain I – Reading Pedagogy (13%)

The competencies include:

  • Foundations of the Science of Teaching Reading
  • Foundations of Reading Assessment

Selected-response questions cover the construction of language, the process of learning spelling, the response to intervention, and key assessment concepts. Basic principles of language include morphology, orthography, syntax, semantics, pragmatics, and segmentation. Stages involved in spelling development include pre-communicative, semi-phonetic, phonetic, transitional, and conventional. The response to intervention is a three-tiered process by which teachers identify and support students’ academic and behavioral needs. Finally, key assessment concepts include congruence, reliability, validity, absence of bias, clarity of language, and determining what is age and grade-level appropriate.

Domain II – Reading Development: Foundational Skills (43%)

There are six competencies:

  • Oral Language Foundations of Reading Development
  • Phonological and Phonemic Awareness
  • Print Concepts and Alphabetic Knowledge
  • Phonics and Other Word Identification Skills
  • Syllabication and Morphemic Analysis Skills
  • Reading Fluency

Concepts examined in this domain include measuring reading fluency, English language learner (ELL) instructional strategies, evaluation of phonemic awareness, the importance of phonological awareness in literacy, syllable awareness, print awareness, directionality, diphthongs, sight words, decodable words, and r-controlled vowels.

Domain III – Reading Development: Comprehension (24%)

The competencies evaluated include:

  • Vocabulary Development
  • Comprehension Development
  • Comprehension of Literary Texts
  • Comprehension of Informational Texts

The four competencies in domain III examine your understanding of concepts like the levels of comprehension, teaching active reading, the three tiers of vocabulary, the types of nonfiction texts, and selecting culturally responsive texts for instruction.

Domain IV – Analysis and Response (20%)

In Domain IV, you’ll find the one constructed-response question. This question centers around a case study of a fictional student. The information provided includes an overview of the student, the skill that you need to assess, and exhibits of the student’s work. With the provided information, you’ll need to construct a 400-600-word response that identifies:

  1. An academic need of foundational reading skills and an instructional strategy to meet that need,
  2. An academic need related to reading comprehension skills and an instructional strategy to meet that need
  3. A descriptive analysis about why you selected those strategies

Your in-depth written response demonstrates your knowledge of the subject matter and should conform to standard English conventions. This response is your own and not copied or paraphrased from other material. Citations are allowed as long as the evidence is appropriately cited in your response. Your answer will be evaluated on the degree of completion, appropriate application of knowledge and skills, and the degree to which you support your response with evidence, examples, and explanations based on relevant content knowledge and skills.

Exam Scoring and Results

An introductory period exists for the new STR exam, and an initial cut score exists to support the transition period. Between January 1, 2021, and September 6, 2021, teacher candidates must meet a minimum threshold of correct items to pass the exam. If that threshold is not met, the candidate does not pass the exam. Exams delivered after September 6, 2021, will have a passing standard determined by the standard-setting committee of Texas educators.

Your exam is scored as a whole, not as individual subtests. Your scaled score for the selected-response sections is combined with the scaled-score for your constructed-response section to produce your overall score. If you do not pass the exam, you are required to retake the entire examination.

Your exam results are available in your candidate account within 28 days of testing. If needed, you can retake the exam 30 days after you receive your results. You can take the exam up to five times.
