State Dyslexia Laws: What All 50 States Now Require and How to Use Them

In 2010, fewer than a dozen US states had any dyslexia-specific legislation. Today, all 50 states have passed at least one law related to dyslexia. The total count, tracked by the International Dyslexia Association's State of Dyslexia database, reached 194 individual statutes as of 2025.

This legislative explosion did not happen by accident. It was the result of fifteen years of sustained parent advocacy, primarily through the Decoding Dyslexia network, combined with mounting scientific consensus around the Science of Reading and investigative journalism exposing the failure of balanced literacy approaches in American classrooms.

The practical question for parents today is not whether your state has a dyslexia law — it almost certainly does — but what specifically your state's law requires, and how to weaponise it in an IEP meeting.

What State Dyslexia Laws Typically Cover

State dyslexia laws are not uniform. They range from comprehensive statutory frameworks (Texas, Arkansas, Colorado) to narrower mandates addressing a single element (screening requirements, teacher training, or definitional language). The most substantive laws address five components:

1. Universal Screening

The most impactful component. States with universal screening mandates require schools to screen every student in the covered grades — typically kindergarten through second or third grade — for dyslexia risk factors using a validated screening tool.

Where screening is mandated, schools cannot use "wait and see" to delay identification. If a student's screener indicates risk, the law typically requires a specific follow-up response within a defined timeframe. Parents in these states can specifically ask: "What did my child's universal screening show, and what response was required under state law?"

Examples identified in the research include: Texas (K-2), Arkansas (K-3), Ohio (K-3), and Colorado; grade coverage and follow-up requirements vary by state.

2. Definition of Dyslexia

States that have codified a definition of dyslexia in their education codes eliminate one of the most common dismissals parents face — the school claiming that dyslexia "isn't a recognised condition" or "isn't separate from general reading difficulties." Where the definition is codified, any attempt by the school to use this argument can be met with the specific statute.

Some state definitions draw on the IDA's definition: dyslexia is a specific learning disability that is neurobiological in origin, characterised by difficulties with accurate and/or fluent word recognition and by poor spelling and decoding abilities, resulting from a deficit in the phonological component of language.

3. Structured Literacy or Evidence-Based Intervention Requirements

The most directly useful for parents: some states explicitly require that intervention for identified dyslexic students use structured literacy approaches that are supported by scientific evidence.

In states with this requirement, a school that continues to use balanced literacy or three-cueing with a dyslexic student after identification may be failing to follow applicable state requirements, not merely best practice.

4. Teacher Training Requirements

Many state laws require teachers to be trained in evidence-based literacy instruction, often specifically including phonological awareness and structured phonics. While this does not create an immediate individual right for a specific student, it establishes that the teaching methodology the school is using must meet the legislative standard.

5. State Dyslexia Handbooks

Several states (Texas, Arkansas, Colorado, Ohio, Utah, and others) have produced state dyslexia handbooks that serve as policy or guidance documents for school districts. These handbooks typically specify evaluation requirements, intervention standards, and district responsibilities.

A state dyslexia handbook is often more detailed and operationally useful than the statute itself. If your state has one, it is a critical document to have at any IEP meeting involving dyslexia identification or intervention.

Colorado's 2025 Dyslexia Law: SB25-200

Colorado's SB25-200, signed in 2025, expanded Colorado's existing Reading to Ensure Academic Development (READ) Act framework in several key ways:

• Added a statutory definition of dyslexia and characteristics of dyslexia
• Expanded the body of evidence and READ Plan provisions used to identify and address reading deficiencies
• Beginning no later than the 2027-28 school year, required each local education provider to implement a universal dyslexia screener or create a universal screening process
• Required the screening process to cover kindergarten during the last 90 days of the school year and grades 1 through 3 during the first 90 days
• Required diagnostic assessment and READ Plan or alternative follow-up procedures when screening identifies dyslexia risk factors

For parents in Colorado, SB25-200 creates specific procedural requirements that local education providers must follow. Once the applicable requirements are in effect, if a child is flagged on the universal screening and the provider does not initiate the required diagnostic and READ Plan or alternative response, the provider may be out of compliance with state law — a different and potentially more actionable claim than a general IDEA dispute.

Colorado also has the Colorado Dyslexia Handbook published by the Colorado Department of Education. Families should check the CDE website for the most current version and related READ Act guidance.

The Most Comprehensive State Dyslexia Frameworks

Texas is one of the more comprehensive state dyslexia frameworks. The Texas Dyslexia Handbook is important state guidance, alongside applicable legal requirements. Texas law requires:

• Universal screening for all students in K-2
• A specific assessment process for students identified at risk
• Use of a dyslexia program with specified characteristics (multisensory, systematic, explicit phonics)
• Detailed documentation requirements

Arkansas was an early leader, with dyslexia legislation dating to 2013 that has been significantly expanded since. Arkansas's framework includes universal screening and intervention requirements.

Ohio has a detailed dyslexia guidebook and requires that school personnel who work with students with dyslexia receive training in structured literacy approaches.

Other states have also enacted screening and intervention provisions, but exact requirements vary by state.

How to Use State Laws in IEP Advocacy

State dyslexia laws are most effective as specific citations in written correspondence and IEP meetings. Instead of general assertions that your child needs structured literacy, cite the specific state requirement:

"Under [State] Statute [number], students identified as at risk through universal screening are required to receive [specific intervention type]. My child was [or was not, and should have been] screened in [grade], and I am requesting documentation of the screening result and the follow-up action taken."

"The [State] Dyslexia Handbook requires that interventions for students with dyslexia be [specific characteristic: multisensory, systematic, explicit]. The current program being offered does not meet this standard because [specific reason]. I am requesting documentation of how the proposed intervention complies with the state handbook requirements."

This framing shifts the conversation from "the parent wants something" to "the district has a specific legal obligation." Schools respond differently to the second framing.

Finding Your State's Laws

Three tools:

1. IDA's Dyslexia Legislation Interactive Map (dyslexiaida.org) — searchable by state, lists specific statutes with brief summaries
2. Dyslegia.com — a detailed legislative information site covering state dyslexia laws
3. State of Dyslexia (stateofdyslexia.org) — state-by-state policy analysis and advocacy resources

For state dyslexia handbooks, search "[your state] Department of Education dyslexia handbook" — most states that have them publish them on the DOE website.

The Dyslexia Support & Reading Intervention Kit includes a state-by-state legislative reference covering the key provisions in major states, the specific language most useful in IEP meetings, and how to combine state law citations with federal IDEA arguments for maximum impact.

The database counted 194 statutes. Not one of them enforces itself.
