This is Part 5 (final) of a 5-part series on Specific Learning Disability identification under IDEA and Texas law.

Throughout this series, we've mentioned Texas-specific requirements alongside federal IDEA regulations. If you're navigating the SLD identification process in Texas, you've probably noticed that the state has additional, highly detailed requirements, especially when dyslexia is involved.
So what makes Texas different? Are the rules inconsistent or contradictory? And what exactly is the Texas Dyslexia Handbook that everyone keeps mentioning?
Let's clear up the confusion and help you understand why Texas has these unique requirements.
The Foundation: Texas Builds on IDEA, Not Against It
First, the good news: Texas rules are not contradictory to federal IDEA regulations. Instead, Texas takes the federal framework and adds specific, mandatory, and detailed requirements that go beyond what federal law requires.
Think of it this way:
IDEA provides the foundation (the minimum requirements all states must meet)
Texas builds a more detailed structure on that foundation (adding specific procedures, especially for dyslexia)
Both are consistent, but Texas is more prescriptive and comprehensive.
Key Differences Between Texas and Federal IDEA Rules
1. Mandatory Labeling Requirements
Federal IDEA:
Permits the use of terms like "dyslexia," "dysgraphia," or "dyscalculia" in evaluation and IEP documents
Does not require their use
Documentation must state whether the child has an SLD
Texas Law:
Requires that when a student is identified with dyslexia and/or dysgraphia, those specific terms must be used in the student's evaluation report and IEP
For formal state reporting (PEIMS data), the category remains "Specific Learning Disability"
Explicitly links conditions to achievement areas (e.g., "Basic reading skill, which may include dyslexia")
Why this matters: Texas eliminates ambiguity. Your child's specific condition must be named, ensuring everyone on the educational team understands the precise nature of the learning disability.
2. Specific Definitions for Dyslexia and Related Disorders
Federal IDEA:
Includes dyslexia as an example of an SLD
Does not provide a specific definition
Mentions related conditions but doesn't define them comprehensively
Texas Law:
Provides a specific state definition of dyslexia: "a disorder of constitutional origin manifested by a difficulty in learning to read, write, or spell, despite conventional instruction, adequate intelligence, and sociocultural opportunity"
Defines "related disorders" including:
Developmental dysgraphia
Developmental auditory imperception
Dysphasia
Specific developmental dyslexia
Developmental spelling disability
Why this matters: Texas leaves no room for interpretation about what constitutes dyslexia and related disorders.
3. Required Team Expertise (The Big One)
This is where Texas requirements become significantly more stringent than federal law:
Federal IDEA:
The evaluation team must include the child's regular teacher
At least one person qualified to conduct individual diagnostic examinations (e.g., school psychologist, educational diagnostician, speech-language pathologist, or remedial reading teacher)
Texas Law:
All of the above, PLUS
Mandatory specialized member when dyslexia is suspected:
Must have specific knowledge of the reading process, dyslexia and related disorders, and dyslexia instruction
Must meet rigorous credential requirements in this priority order:
Licensed Dyslexia Therapist (LDT)
Most advanced dyslexia-related certification recognized by the State Board of Education
If neither is available, completion of TEA Texas Dyslexia Academies and comprehensive training requirements
For dysgraphia evaluations:
Texas notes that there likely needs to be an occupational therapist on the committee due to the graphomotor component
Required documentation:
The specialized dyslexia member must sign a document describing their participation in the evaluation and any resulting IEP
Why this matters: Texas ensures that highly trained specialists are involved in dyslexia identification—not just general educators or psychologists without specific dyslexia expertise.
4. Mandatory Early Screening
Federal IDEA:
"Child Find" requires identifying children who need special education
Emphasizes using RTI, but not to delay evaluation
Texas Law:
Universal screening mandate: All kindergarten students must be screened for dyslexia at the end of the school year
All first-grade students must be screened as close to mid-year as possible, but no later than January 31
This is in addition to general reading assessments required under Texas Education Code §28.006
Why this matters: Texas proactively identifies children with dyslexia early, rather than waiting for them to fail.
5. Terminology for Language Learners
A minor but notable difference:
Federal IDEA: Uses "Limited English Proficiency" (LEP)
Texas: Uses "Being emergent bilingual"
Both refer to the same exclusionary factor—ensuring language acquisition isn't mistaken for a learning disability.
6. Progress Reporting for Dyslexia
Federal IDEA:
Progress reporting is determined by the IEP team
General requirements for tracking IEP goals
Texas Law:
Schools must provide parents with information about the student's progress in dyslexia instruction at least once each grading period
More frequent reporting if specified in the IEP
Why this matters: Texas mandates regular communication, specifically about dyslexia intervention progress.
Who Can Evaluate a Child for SLD in Texas?

The evaluation must be conducted by a collaborative group that includes:
Core Members (Required for All SLD Evaluations):
The child's parents
General education teacher (or equivalent if the child doesn't have one, or a qualified individual for children under school age)
At least one diagnostic professional:
Additional Required Member (When Dyslexia/Dysgraphia Is Suspected):
Dyslexia specialist with credentials described above
Other Professionals (As Needed):
Occupational therapist (especially for dysgraphia)
LPAC representative (for emergent bilingual students)
Important: The final body making the eligibility determination in Texas is the Admission, Review, and Dismissal (ARD) Committee. Each member must certify in writing whether the evaluation report reflects their conclusion.
What Is the Texas Dyslexia Handbook?
Official Title:
What It Is:
A comprehensive regulatory document approved by the Texas State Board of Education (SBOE) that describes the procedures school districts and charter schools must follow when dealing with students who have, or are suspected of having, dyslexia and related disorders.
What It Contains:
Evaluation procedures that must be included in a comprehensive evaluation for dyslexia (aligned with IDEA requirements)
Identification criteria and required assessment components
Instructional requirements including evidence-based components and delivery methods
Accommodation guidelines for students with dyslexia
Parent rights information and resources
Why Texas Has It:
Legislative mandate: Texas Education Code §38.003 requires:
Screening and testing students for dyslexia
Providing treatment (instruction) for students with dyslexia
The SBOE to approve a comprehensive program for these activities
Historical context: Texas has supported reading instruction and dyslexia identification since 1986, one of the longest-running state programs of its kind.
Explicit SLD recognition: Texas law explicitly states that dyslexia meets the definition of an SLD under IDEA. Because dyslexia is such a significant, recognized condition, Texas uses the Handbook to mandate a specialized, consistent approach statewide.
Ensuring quality: The Handbook ensures that:
Evaluation components are comprehensive and research-based
Instructional programs are evidence-based
Procedures comply with both federal IDEA and Section 504 requirements
All districts follow the same high standards
Who Wrote It:
The State Board of Education (SBOE) approves and adopts the Handbook, though the Texas Education Agency (TEA) provides guidance and frequently asked questions.
The Handbook is modified by the SBOE only with broad-based input from educators and professionals in reading and dyslexia from across the state.
Current status: The 2024 edition is the most recent version.
Understanding Dyslexia as Specially Designed Instruction (SDI)
One of the most important clarifications Texas provides addresses a common source of confusion:
The Question:
Should a student with dyslexia receive services under IDEA (special education) or Section 504 (general education accommodations)?
Texas's Answer:
Evidence-based dyslexia instruction is considered Specially Designed Instruction (SDI) and is therefore a special education service.
What this means:
If a child is identified with dyslexia (meets the first prong of IDEA eligibility)
AND the ARD committee determines the student requires dyslexia instruction (SDI)
THEN the child is eligible under IDEA (not just Section 504)
Why this matters: This clarification ensures students with dyslexia receive the full protections and services of IDEA, not just accommodations under Section 504.
Are the Rules Inconsistent? No.
Despite having more detailed requirements, Texas rules are not inconsistent with federal IDEA regulations:
Areas of Complete Consistency:
Core definition of SLD (identical)
Recognition of dyslexia as an SLD (both include it)
Permitted identification models (RTI and PSW allowed in both)
Prohibited model (severe discrepancy cannot be required) ✓ Exclusionary factors (same general categories)
Requirement to rule out a lack of appropriate instruction
Where Texas Adds Detail (Not Contradiction):
Specific definitions and mandatory labeling
Higher team expertise requirements
Mandatory early screening
Comprehensive evaluation procedures (the Handbook)
Clear identification of dyslexia instruction as SDI
Think of it this way: IDEA sets the floor; Texas raises the ceiling.
Common Areas of Confusion (Now Resolved)
Confusion #1: "Can we just use accommodations for dyslexia?"
Resolution: Texas clarifies that evidence-based dyslexia instruction is SDI, making it a special education service, not just an accommodation.
Confusion #2: "Does IDEA really cover dyslexia?"
Resolution: Both federal and Texas law explicitly state that dyslexia is an SLD. Texas goes further by requiring the term be used in documentation.
Confusion #3: "Who's qualified to identify dyslexia?"
Resolution: Texas removes ambiguity by requiring specific credentials (LDT or advanced certification) for team members when dyslexia is suspected.
Confusion #4: "When should we screen for dyslexia?"
Resolution: Texas mandates universal screening in K and 1st grade, no waiting for failure.
