How to Navigate the Texas Dyslexia 504-to-IEP Transition Without an Attorney

If your child has dyslexia in Texas and is currently on a 504 plan receiving only accommodations (extended time, audiobooks, reduced assignments) instead of direct multisensory reading instruction through an IEP, you can force the transition without hiring an attorney. HB 3928 and the 2024 Dyslexia Handbook update mandate that Texas districts evaluate students who need direct dyslexia instruction under IDEA — not park them on 504 plans with minimal accommodations. The process requires specific written requests citing exact regulations, documented follow-ups, and knowledge of escalation options when the district resists. Here's the complete roadmap.

Why Districts Resist the 504-to-IEP Transition

Understanding the resistance is essential to overcoming it. Districts push back on 504-to-IEP transitions for dyslexia because IEPs are dramatically more expensive and legally binding than 504 plans:

• 504 plans cost the district almost nothing. Extended time on tests and access to audiobooks require no additional staff, no specialized instruction, and no progress monitoring. The district checks a box and moves on.
• IEPs require Specially Designed Instruction. For dyslexia, this means multisensory structured literacy instruction delivered by a Certified Academic Language Therapist (CALT) or Licensed Dyslexia Therapist (LDT). Districts must hire or contract these specialists.
• IEPs create legal accountability. Every goal in an IEP is legally enforceable. If the district fails to deliver services documented in the IEP, parents can file for compensatory education. 504 plans have no equivalent enforcement mechanism.
• The post-8.5% cap backlog. For years, Texas districts suppressed special education identification under the now-illegal 8.5% cap. HB 3928 and the 2024 Dyslexia Handbook are forcing districts to evaluate students they previously avoided evaluating. Many districts lack the CALT/LDT staffing to deliver the instruction that IEPs require.

Common district tactics for blocking the transition:

• "Your child is doing fine on the 504 — the accommodations are working."
• "Dyslexia is already being addressed through the 504 plan."
• "We don't need to do a full evaluation because the 504 data is sufficient."
• "Your child's grades are passing, so there's no adverse educational impact."

Every one of these statements is either misleading or legally incorrect under the current Texas framework. Here's how to counter them.

The Step-by-Step Process

Step 1: Determine If Your Child Qualifies for IDEA Evaluation

Under the 2024 Dyslexia Handbook and HB 3928, your child should be evaluated under IDEA (triggering the FIIE and the path to an IEP) if any of the following are true:

• Your child requires direct, explicit, multisensory structured literacy instruction — not just accommodations
• Your child is not making adequate progress with the accommodations provided under the 504 plan
• Your child needs Specially Designed Instruction (instruction specifically adapted to the child's needs, beyond what general education provides)
• The 504 accommodations are reducing demands rather than building skills (extended time helps a student finish, but it doesn't teach them to decode)

If your child is receiving only accommodations — extended time, preferential seating, audio versions of textbooks, reduced assignments — and their reading fluency, decoding accuracy, or comprehension have not measurably improved, the 504 plan is managing the disability rather than addressing it. That's the legal trigger for an IDEA evaluation.

Step 2: Submit a Written Request for FIIE

Send a written request (email is sufficient — you need the timestamp) to the special education director, not just the classroom teacher or 504 coordinator. The request must specifically reference IDEA evaluation, not a 504 reevaluation.

Key elements to include in the letter:

• Your child's name, grade, campus, and current 504 plan status
• A statement that you are requesting a Full Individual and Initial Evaluation (FIIE) under IDEA for suspected Specific Learning Disability (dyslexia)
• Reference to HB 3928 and the 2024 Dyslexia Handbook requiring IDEA evaluation for students needing direct dyslexia instruction
• A statement that 504 accommodations alone have not resulted in adequate progress
• A request for the district's response in writing within 15 school days (the timeline for the district to respond to a parent referral)

This letter starts the clock. The district has 15 school days to respond with either consent to evaluate or Prior Written Notice (PWN) explaining why they're refusing.

Step 3: If the District Refuses — Counter the PWN

If the district issues Prior Written Notice refusing to evaluate, they must explain their reasoning in writing. Common reasons and how to counter:

"The student is making adequate progress under the 504 plan." Counter: Request the specific data the district is using to define "adequate progress." Under Endrew F. v. Douglas County School District (2017), the standard is not minimal progress — it's progress "appropriate in light of the child's circumstances." If your child's reading level has plateaued or is not closing the gap with grade-level peers, the 504 plan is not providing adequate progress.

"There is no suspected disability under IDEA." Counter: Dyslexia is a Specific Learning Disability under IDEA. The 2024 Dyslexia Handbook explicitly classifies it as such. If the district has already identified your child as having dyslexia (through the 504 process), the disability is not "suspected" — it's documented. The question is whether the child needs Specially Designed Instruction, which triggers IDEA.

"The 504 plan addresses the student's needs." Counter: A 504 plan provides accommodations — adjustments to how the student accesses the curriculum. An IEP provides Specially Designed Instruction — direct instruction adapted to the student's specific disability-related needs. If the student needs multisensory structured literacy instruction from a CALT or LDT, that is Specially Designed Instruction, and a 504 plan cannot provide it.

Step 4: The FIIE Process (45 School Days)

Once the district agrees to evaluate (or you've overcome their refusal), the timeline is strict:

• Day 0: You sign consent for the FIIE
• 45 school days: The district must complete the Full Individual and Initial Evaluation
• 30 calendar days after the FIIE is complete: The ARD committee must meet to determine eligibility and develop the IEP

During the FIIE, the evaluation team (typically an educational diagnostician and/or LSSP) will assess cognitive processing, academic achievement, and the specific patterns associated with dyslexia. Request that the evaluation include:

• Comprehensive reading assessment (decoding, fluency, comprehension)
• Phonological processing assessment (CTOPP or equivalent)
• Orthographic processing
• Rapid automatized naming
• Written expression

Step 5: The ARD Meeting — Securing the IEP

At the ARD meeting following the FIIE, the committee determines eligibility under IDEA. For the 504-to-IEP transition, you need:

• Eligibility under Specific Learning Disability (SLD): The FIIE must document that dyslexia adversely affects educational performance and the child needs Specially Designed Instruction
• Specially Designed Instruction in the IEP: The IEP must specify multisensory structured literacy instruction — not just accommodations carried over from the 504 plan
• Qualified provider: The IEP should specify instruction from a CALT or LDT where available
• Measurable goals: Reading fluency, decoding accuracy, and comprehension goals with specific baselines and targets

If the ARD committee attempts to find the child eligible but write an IEP that mirrors the old 504 accommodations (extended time, audiobooks) without adding Specially Designed Instruction, the IEP fails the purpose of the transition. This is where the 10-day recess becomes critical — invoke it under TAC §89.1050 to review the proposed IEP and gather additional data.

Escalation Without an Attorney

If the district stonewalls at any stage, Texas parents have free or low-cost escalation options:

TEA State Complaint — Free. You file directly with the Texas Education Agency. TEA must investigate and resolve within 60 calendar days. This is often the most effective tool for forcing compliance with evaluation timelines and the dyslexia transition mandate.

IEP Facilitation — Free. TEA provides a trained facilitator for the ARD meeting. The facilitator doesn't make decisions but keeps the meeting productive and ensures both sides are heard.

Mediation — Free through TEA. A neutral mediator helps you and the district reach agreement. Mediation agreements are legally binding.

Due Process — This is where an attorney becomes valuable. Due process hearings through SOAH (State Office of Administrative Hearings) are adversarial proceedings. You can represent yourself (pro se), but the district will have legal counsel. Consider an attorney if you reach this stage.

For most 504-to-IEP transitions, a TEA State Complaint resolves the issue without ever reaching due process.

The Paper Trail That Wins

The difference between a parent who succeeds without an attorney and one who doesn't is documentation. Every interaction should generate a written record:

1. Initial request for FIIE — emailed, timestamped
2. District response — Prior Written Notice, consent form, or refusal
3. Your counter to any refusal — citing HB 3928, the 2024 Dyslexia Handbook, and specific data showing inadequate progress
4. FIIE timeline tracking — documented milestones within the 45-school-day window
5. ARD meeting notes — your written summary sent to the committee within 48 hours of the meeting
6. 10-day recess invocation — formal written request if you disagree with the proposed IEP

Who This Is For

• Parents of children with diagnosed dyslexia who are currently on a 504 plan in Texas and receiving only accommodations (no direct multisensory instruction)
• Parents whose child's reading levels have plateaued despite 504 accommodations
• Parents who have been told by the district that "the 504 is sufficient" or "we don't need to evaluate under IDEA"
• Families who cannot afford $300-$500/hour for a special education attorney to manage the transition
• Parents in districts that are actively resisting the HB 3928 transition mandate

Who This Is NOT For

• Parents whose child is making documented, measurable reading progress on the current 504 plan — if the accommodations are genuinely working, the 504 may be appropriate
• Parents seeking direct dyslexia therapy services outside the school system (private tutoring, Lindamood-Bell, Orton-Gillingham clinics) — those are separate from the school IEP
• Parents whose child has already been evaluated under IDEA and found not eligible — a different appeal process applies

Frequently Asked Questions

Can the school refuse to evaluate my child for an IEP if they're already on a 504?

The district can issue Prior Written Notice explaining why they believe an evaluation isn't warranted. However, they cannot categorically refuse to evaluate a child with dyslexia who may need Specially Designed Instruction. Under HB 3928 and the 2024 Dyslexia Handbook, students requiring direct dyslexia instruction must be evaluated under IDEA. If the district refuses, file a TEA State Complaint — it's free and typically resolves within 60 days.

What's the difference between 504 accommodations and IEP Specially Designed Instruction for dyslexia?

504 accommodations modify how your child accesses the existing curriculum — extended time, audiobooks, reduced assignments, preferential seating. They don't change what or how the child is taught. IEP Specially Designed Instruction changes the instruction itself — multisensory structured literacy (Orton-Gillingham based approaches) delivered by a trained specialist (CALT or LDT). One manages the disability; the other addresses it.

How long does the 504-to-IEP transition take in Texas?

From your initial written request to the first IEP being in place: typically 3-5 months. The district has 15 school days to respond to your request, 45 school days to complete the FIIE after you sign consent, and 30 calendar days after the FIIE to hold the ARD meeting. Districts sometimes drag these timelines — the Texas IEP Blueprint includes a timeline tracker to hold them accountable.

What if my child's school doesn't have a CALT or LDT on staff?

The district's staffing limitations do not limit your child's right to appropriate services. If the IEP specifies multisensory structured literacy instruction from a CALT or LDT, the district must either hire one, contract with one, or provide equivalent qualified instruction. "We don't have the staff" is not a legal basis for denying services.

Do I need to cancel the 504 plan before requesting an IEP evaluation?

No. The 504 plan remains in place during the evaluation process and until the IEP is developed and implemented. If the child is found eligible under IDEA, the IEP replaces the 504 plan. If the child is found not eligible, the 504 plan continues unchanged.
