Both are legal protections for students with disabilities, and both matter. But they run on different laws, different eligibility standards, and different timelines — and mixing them up can leave a student without what they actually need. Here's the plain-language version, plus what to do when a parent brings it up.
Section 504 →
Removes barriers so a student can access what's already being taught.
Special Education (ARD) →
Changes how a student is taught, because they need something different.
A student is on one path or the other, never both.
An IEP already carries every protection Section 504 provides, so a student who qualifies for special education doesn't also get a 504 plan on the side. The two aren't stacked layers; they're two answers to the same question. What separates them is services: a 504 plan gives a student access to the instruction everyone else is getting, and an IEP gives a student instruction designed for them. If the student needs the second thing, the 504 plan isn't the right container for it.
Side by Side
| Section 504 | Special Education (ARD) | |
|---|---|---|
| The Law | Section 504 of the Rehabilitation Act of 1973 — a civil rights law. | IDEA (Individuals with Disabilities Education Act) — a federal education law. Texas calls the meeting an ARD (Admission, Review, Dismissal). |
| The Core Question | Does the student have a disability that substantially limits a major life activity, and do they need help accessing what's already being taught? | Does the student have a qualifying disability, is their educational performance affected, and do they need specially designed instruction — a different way of being taught? |
| Who Qualifies | Any student with a physical or mental impairment that substantially limits a major life activity (learning, reading, concentrating, breathing, walking, and more). There is no set list of conditions. | A student who fits one of 13 disability categories (e.g., Specific Learning Disability, Autism, Other Health Impairment, Speech Impairment, Emotional Disturbance) and needs specialized instruction because of it. |
| The Evaluation | Reviews existing data and documentation — school records, teacher input, sometimes outside evaluations. No federally mandated formal process or state-set clock. | A Full Individual and Initial Evaluation (FIE) — a formal, comprehensive evaluation done with parent consent, strict legal timelines, and state-certified evaluation personnel. |
| Who's on the Team | The campus 504 Committee — staff who know the student (teacher, counselor, administrator) plus the parent. | The ARD Committee — parent, general education teacher, special education teacher, an LEA representative, and someone who can interpret evaluation data (often the diagnostician). |
| The Plan | A 504 Plan, sometimes called an Accommodation Plan. | An IEP (Individualized Education Program), developed through the ARD process. |
| What the Student Gets | Accommodations — changes to how the student accesses instruction that's already happening (extra time, preferential seating, breaks, a modified test format). | Specially designed instruction and, when needed, related services (like speech therapy or counseling) — changes to how the student is taught, with measurable goals. |
| Review Schedule | Reviewed periodically on the district's timeline, often annually. Reevaluated before major changes. | Reviewed at least annually at an ARD meeting. Fully reevaluated at least every three years. |
| If a Family Disagrees | They can request a 504 due-process hearing or file a complaint with the Office for Civil Rights. | Formal IDEA procedural safeguards apply — mediation, a due process hearing, or a state complaint. |
Quick Gut-Check
Neither list is a checklist for eligibility — that's always a team decision built on data. But if you're trying to name what you're seeing, start here.
Might sound like 504
- The student can access grade-level work once the right supports are in place.
- A physical or health condition affects access to school (e.g., diabetes, a food allergy, a temporary injury, ADHD without other complications).
- The student needs procedural adjustments, not different instruction.
Might sound like Special Education
- The student isn't making progress even with accommodations and interventions already in place.
- The student needs to be taught differently, not just given more time or a different format.
- Concerns show up across settings and over time, backed by MTSS/RTI data.
If a Parent Asks — What Actually Happens
A parent doesn't need to know whether to ask for "504" or "special ed" by name. All they have to do is put the concern in writing — here's what happens next, and what's actually required of the campus at each step.
1
A request doesn't have to be formal
An email, a note home, or something said at a parent-teacher conference all count. Encourage the parent to put it in writing and name the specific concern — that's what starts the clock.
2
The campus routes it — the team decides which path
Whoever receives the request loops in campus leadership right away: the 504 coordinator if it sounds like an access issue, or an administrator/diagnostician if it sounds like the student needs to be taught differently. It's not the teacher's call alone, and it isn't the parent's either — that's what the evaluation is for.
3
The district responds in writing, either way
For a special education referral, Texas law requires a decision within 15 school days of a written request — either prior written notice proposing an evaluation (with a consent form) or written notice explaining why the district is declining (TEC §29.004(c)). Section 504 doesn't carry that same state-set clock; the timeline lives in the district's local 504 procedures. Either way, a parent should never get a verbal "no."
4
The evaluation happens
Once a parent signs consent for a special education evaluation, the district has 45 school days to complete the FIE, and the ARD convenes within 30 calendar days after that to review results and determine eligibility (TEC §29.004; 19 TAC §89.1011). For 504, the committee reviews existing data — school records, teacher input, sometimes an outside evaluation — with no comparable state-mandated clock, though a documented, multi-source review is still the standard.
5
If the family disagrees
Both paths have a formal way to push back. Special education carries IDEA's procedural safeguards — mediation or a due process hearing. Section 504 allows a district-level due process hearing or a complaint to the Office for Civil Rights. Neither path ends the conversation at "no."
After Eligibility — The Special Education Side
The initial ARD is the first meeting, not the last. "ARD" is an umbrella term for any meeting of the ARD committee; the word in front of it says why the committee is meeting. Names vary a little by district, so check what yours calls each one.
1 Referral→
2 FIE (45 school days)→
3 Initial ARD: eligibility + IEP→
4 Services delivered→
5 Annual ARD (every year)→
6 REED → Reevaluation (every 3 years)
↩ then back to step 3: eligibility is confirmed or ended, and the IEP is rewritten. Revision ARDs and amendments can happen anywhere between steps 3 and 6.

Leaving the path
| Meeting or Step | What It Is | Why It Happens | What the Teacher Brings | Good to Know |
|---|---|---|---|---|
| Initial ARD | The first ARD after the FIE. The committee decides eligibility and, if the student qualifies, writes the first IEP. | The FIE is complete. Texas requires this meeting within 30 calendar days of the evaluation report. | Current classroom performance, what's been tried, and where the student is now relative to peers. | A student has exactly one initial ARD. Everything after it is a review, revision, or reevaluation. |
| Annual ARD | The required yearly review of the whole IEP: progress on goals, services, accommodations, placement, and any new needs. | IDEA requires the IEP to be reviewed at least once every 12 months. | Progress data on IEP goals, grades, work samples, and an honest read on which accommodations are actually being used. | The annual date and the reevaluation date run on separate clocks. They can line up, but they don't have to. |
| Revision ARD (sometimes "Brief ARD") |
A meeting called before the next annual to address one specific issue. | A new concern, a change in services or placement, new evaluation results, or a parent or teacher request. | Data on the specific concern that triggered the meeting. | A revision ARD doesn't reset the annual date. If the change is small and everyone agrees, an amendment may work instead. |
| ARD Amendment | A written change to the current IEP made by agreement between the parent and the district, without reconvening the full committee. | A change that doesn't warrant a meeting, such as adjusting an accommodation or updating a service minute count within the same setting. | Usually just input on whether the proposed change fits what you're seeing. | Allowed under IDEA (34 CFR §300.324(a)(4)), but local procedures decide what can be amended and what needs a meeting. Eligibility and placement changes generally need a meeting. |
| REED | Review of Existing Evaluation Data. An evaluation step, not a meeting type. | Before any reevaluation, the team looks at what's already known and decides whether new testing is needed. | This is where teacher input carries the most weight: rating scales, observations, and a clear picture of current performance. | A REED can conclude that no new testing is needed. That's still a reevaluation, and it still gets reviewed at an ARD. |
| Reevaluation | New data gathered (when the REED says it's needed) to reconsider eligibility and current needs. | At least every three years unless the parent and district agree it's unnecessary; sooner if conditions warrant or someone requests it. | Whatever the REED identified as missing, often classroom data and updated rating scales. | Not more than once a year unless the parent and district agree. Results are reviewed at an ARD, either a separate one or the next annual. |
| Dismissal ARD | The meeting that ends special education services. | Reevaluation shows the student no longer meets eligibility criteria or no longer needs specially designed instruction. | Evidence the student is succeeding without specialized instruction, not just without pull-out. | A reevaluation is required before dismissal, except at graduation or aging out. Dismissal is where the 504 question comes back (see below). |
| Other ARDs | Transition ARDs, graduation ARDs, and manifestation determination ARDs (discipline) each have their own rules. | A specific event: the student turns 14, approaches graduation, or faces a disciplinary change of placement. | Depends on the meeting. Ask your diagnostician or case manager what's needed. | Each is still an ARD committee meeting. The modifier tells you the purpose. |
After Eligibility — The 504 Side
A 504 plan isn't a one-time form. It has fewer federal timelines than an IEP, but it still has a cycle, and the plan stays in effect until the committee changes it.
| Meeting or Step | What It Is | Why It Happens | What the Teacher Brings | Good to Know |
|---|---|---|---|---|
| Initial 504 Meeting | The committee reviews data, decides eligibility, and writes the plan in the same meeting. | A referral came in and the committee has gathered enough to decide. | What's been tried, how the student responded, and where the impairment shows up at school. | Eligibility and accommodations are two separate decisions. A student can be eligible and need very few accommodations. |
| Periodic Review | A look at whether the plan is still the right plan. | Most districts review annually; Section 504 says "periodically" and leaves the schedule to local procedure. | Which accommodations the student actually uses, which ones don't get used, and whether the gap is closing. | Accommodations that sit unused on a plan for a year are a signal, not a formality. Say so at the review. |
| Reevaluation | A fresh look at eligibility and need, using updated data. | Required before any significant change in placement (34 CFR §104.35(d)); many districts also reevaluate every three years to mirror IDEA. | Current data, plus any new outside documentation the family has shared. | "Significant change in placement" includes removal from the plan and long disciplinary removals, not just a move to another program. |
| Dismissal from 504 | The committee determines the student no longer has an impairment that substantially limits a major life activity. | Usually after reevaluation shows the condition has resolved or no longer affects school access. | Evidence the student is accessing instruction without the accommodations, not just tolerating their absence. | Mitigating measures (medication, glasses, therapy) can't be the reason for dismissal. Eligibility is judged as if they weren't in place. |
Moving Between Paths
The two paths aren't sealed off from each other. Students move between them, and the move usually starts with a teacher noticing something.
From 504 to special education
A 504 plan is not a waiting room, and it is not a reason to delay a referral. Refer when:
- The gap isn't closing even though the accommodations are being used as written.
- The committee keeps adding accommodations at each review and none of them change the outcome.
- The concern shows up across settings and over time, and the student seems to need different instruction, not just different access.
From special education to 504
Dismissal from special education ends specially designed instruction. It doesn't end the disability. When a student is dismissed:
- The 504 committee should consider eligibility right away, using the reevaluation data the ARD just reviewed.
- Many dismissed students still have an impairment that substantially limits learning, concentrating, or another major life activity. They usually qualify.
- The accommodations that were working in the IEP are the obvious starting point for the 504 plan.
Evaluated for special education, not eligible
An FIE that doesn't find IDEA eligibility often still documents an impairment. That data belongs in front of the 504 committee. "Not eligible for special education" and "doesn't need anything" are two different conclusions, and the campus should make sure the second one isn't assumed from the first.
Common Myths
Myth: "504 is the easier option, so let's use it instead of testing for special education."
Reality: If a student needs specially designed instruction, a 504 alone isn't legally sufficient — and skipping a referral can be considered a denial of FAPE.
Myth: "A doctor's note automatically qualifies a student for services."
Reality: A diagnosis alone doesn't create eligibility. The campus team still has to gather school-based data showing substantial limitation (504) or adverse educational impact plus a need for specialized instruction (special education).
Myth: "Every student with an IEP also needs a separate 504 plan."
Reality: A student is never on both at once. An IEP already carries all the protections of Section 504, and the accommodations a 504 plan would hold belong in the IEP itself. If someone proposes "an IEP plus a 504," the question to ask is what the 504 would provide that the IEP can't. The answer is nothing.
Myth: "The 504 isn't working, so let's add more accommodations."
Reality: More of the same access support won't fix a need for different instruction. A plan that keeps growing without changing the outcome is a referral signal, not a formatting problem.
Myth: "Bad grades mean a student needs to be referred for testing."
Reality: Grades alone aren't enough. A referral should be based on a suspicion of disability, supported by data — not a single low grade or missing assignment.
When in Doubt
Talk to your campus 504 coordinator or educational diagnostician early — before a plan exists on paper. Bring what's already been tried and what the data shows. That conversation is usually the fastest way to figure out which path, if either, actually fits the student in front of you.
