Mississippi Dyslexia Screening, Testing, and IEP vs. 504: What Parents Need to Know

Your child's teacher mentions they "failed" the fall reading screener. Or maybe Kindergarten ended and a letter came home about a dyslexia screening result. Either way, you're holding a piece of paper that says your child is at risk — and you have no idea what happens next.

Here's what the law actually requires, what a screener versus a full evaluation means, and how to push for the right plan for your child.

What Mississippi Law Requires: MS Code § 37-173-15

Mississippi is one of a handful of states with a specific statutory mandate for universal dyslexia screening. Under MS Code § 37-173-15, every local school district must screen every student for dyslexia characteristics using a State Board of Education-approved screener. The required screening windows are:

• Spring of Kindergarten
• Fall of Grade 1

This is not optional and not triggered by a parent request — it is a universal obligation for every public school in the state. If your child attended a Mississippi public school during those windows and was not screened, that is a procedural violation you can raise in writing.

The screeners used must be approved by the MDE. When a student shows indicators of dyslexia risk on the screener, the district is then obligated to notify the parent and begin tiered reading interventions.

Screener vs. Full Dyslexia Evaluation: A Critical Difference

This is where many Mississippi families lose ground. A screener is a brief, group-administered tool — think of it as a smoke detector, not a fire investigation. A positive result on the screener means your child needs more investigation, not that the process is complete.

A comprehensive dyslexia evaluation is a full psychoeducational assessment conducted by a licensed school psychologist or educational diagnostician. It typically includes:

• Phonological processing measures (phonological awareness, phonological memory, rapid naming)
• Decoding and word recognition tasks
• Reading fluency and comprehension assessments
• Spelling and written expression screening
• Cognitive processing components if needed for eligibility

A screener result alone is not sufficient to qualify a child for special education services or even a 504 plan. You need the full evaluation to establish eligibility and document the severity of the deficit.

How to request it: Send a written request to the school's principal or special education director requesting a comprehensive psychoeducational evaluation to determine whether your child has a Specific Learning Disability in reading, including dyslexia characteristics. Under Mississippi State Board Policy 74.19, the district must respond and, if they agree to evaluate, complete the evaluation within 60 calendar days of receiving your signed consent.

If the school says they want to monitor your child in MTSS tiers for several more months before evaluating, you can still formally request the evaluation in writing. The 60-day clock starts when they receive your consent, not when the school decides it is convenient.

Does My Child Need an IEP or a 504 Plan?

This is the most common question Mississippi parents ask after a dyslexia diagnosis or evaluation. The short answer: it depends on whether your child needs specially designed instruction or just accommodations to access instruction they can already manage.

IEP (under IDEA):

• Requires the child to have a disability in one of 13 categories — Specific Learning Disability (SLD) is the most common pathway for dyslexia
• The child must require specially designed instruction to make meaningful progress, meaning the curriculum, methodology, or delivery itself must be modified
• Provides structured Orton-Gillingham or similar evidence-based reading interventions delivered by a special education teacher
• Comes with procedural protections including Prior Written Notice, annual reviews, and dispute resolution rights
• Mississippi uses a 60% weight for SLD students in the Mississippi Student Funding Formula, meaning the district receives additional funding to serve your child

504 Plan (under Section 504):

• Broader eligibility — any physical or mental impairment that substantially limits a major life activity (learning, reading)
• Does not require specially designed instruction — appropriate when the child can access grade-level content with environmental supports and accommodations
• Common accommodations for dyslexia: extended time, text-to-speech tools, reduced-distraction testing environments, oral administration of written tests, access to audio versions of reading materials
• Important: any accommodation used on Mississippi statewide assessments (MAAP) must be documented in the 504 plan before the test and must be routinely used in day-to-day instruction

If your child has a formal diagnosis of dyslexia and is significantly behind grade level in reading despite prior instruction, they will typically qualify for an SLD evaluation and an IEP. If the gap is smaller and the child can largely access grade-level content with some supports, a 504 may be the appropriate vehicle.

Be cautious about accepting a 504 when an IEP is warranted. A 504 does not provide specially designed reading instruction — it only adjusts how existing instruction is delivered. A child with significant phonological processing deficits needs structured literacy intervention, which lives inside an IEP.

The Third Grade Gate Connection

Mississippi's Literacy Based Promotion Act (LBPA) means that students identified with reading deficiencies at the end of third grade face mandatory retention unless they qualify for a "Good Cause Exemption." One of the recognized exemptions covers students with disabilities who have an active IEP or 504 plan that addresses the reading deficiency.

This creates a clear, time-sensitive argument for acting early. A parent whose child receives a positive dyslexia screener result in Kindergarten or first grade has two to three years to secure the right plan and services before that third-grade gate appears. A child who begins structured literacy intervention with an IEP in first grade is in an entirely different position than a child who arrives at third grade with only informal classroom supports.

If your child is in K-2 and received a screener result indicating dyslexia risk, request the full evaluation now. Do not wait for the school to propose it on their timeline.

When the School Says Your Child "Doesn't Qualify"

A district evaluation that results in "does not qualify" is not the final word. Under IDEA regulations adopted by Mississippi, you have the right to request an Independent Educational Evaluation (IEE) at public expense if you disagree with the district's evaluation. Upon receiving that request, the district must either agree to fund the external evaluation immediately or file a due process complaint to defend its own evaluation as appropriate.

IEEs are particularly important in dyslexia cases because district-level evaluations sometimes use screeners or informal tools rather than gold-standard measures. An independent evaluator using comprehensive phonological processing batteries may reach a different conclusion.

Additionally, if the school evaluated your child and found no SLD but your child continues to struggle, consider whether a 504 referral is appropriate based on the same evaluation data. The 504 eligibility standard is broader than IDEA's SLD criteria.

Putting It Together

If the dyslexia screener came back positive:

1. Request the full psychoeducational evaluation in writing — do not wait for the school to propose it
2. Sign consent promptly so the 60-day clock starts
3. At the eligibility meeting, ask the team to specify whether specially designed instruction is needed or whether accommodations alone are sufficient
4. If the team recommends a 504 only and your child is significantly below grade level in reading, request the team explain in writing why an IEP is not appropriate (this is a Prior Written Notice trigger)
5. Keep all screener reports, evaluation results, and meeting notes in a home binder

The Mississippi IEP & 504 Blueprint includes evaluation request templates, a guide to reading the psychoeducational report your child's school will produce, and a checklist for the eligibility meeting — so you arrive prepared rather than reactive.

What About Private Dyslexia Evaluations?

Private neuropsychological or educational therapy evaluations are not free, but they carry significant weight in IEP proceedings. If you have obtained a private evaluation diagnosing dyslexia, bring it to the eligibility meeting and request that the IEP team consider it. Under IDEA, the team must consider private evaluations; they are not required to accept every recommendation, but they must document in writing why they are not following any recommendation they reject.

If you present a private evaluation and the school still denies eligibility, that written rejection becomes the foundation of a state complaint or due process filing.

Mississippi parents navigating dyslexia evaluations are dealing with a system under documented federal scrutiny — OSEP's July 2025 Differentiated Monitoring and Support report cited the state for ten distinct findings of systemic noncompliance. Knowing your procedural rights is not optional. It is the single most effective thing you can do for your child's educational trajectory.
