UDL vs accommodations

By the IEP Atlas editorial teamLast updated November 1, 2026

Short answer

Universal Design for Learning is how a teacher plans a lesson so every student has options from the start. An accommodation is a specific change written into one student's IEP or 504 plan, which the school must provide. Ask: is this offered to everyone, or is it owed to this student? If owed, it is an accommodation and must be documented.

UDL and accommodations often look the same in a classroom. Audio versions of a text, a choice of how to show learning, a graphic organizer: any of these can be either one. The difference is who it is for and whether it is required.

Universal Design for Learning is a framework for planning instruction so it works for students with very different needs. The CAST guidelines organize it around multiple means of engagement, representation, and action and expression.^[1] An accommodation is a change in how one student learns or shows learning, decided by the IEP team and written in the IEP.^[3] For the basics on accommodations, see the pillar on IEP accommodations.

The deciding question

Ask: if this option disappeared from the lesson tomorrow, would the school be out of compliance for a particular student?

If no, it is UDL. The teacher offers it because it helps many students, and can change it.
If yes, it is an accommodation. It is written for that student, and every teacher must provide it, every time it applies.

A good UDL classroom reduces how many separate accommodations a student needs. It does not remove the duty to provide the ones in the IEP.

UDL vs accommodations side by side

	UDL	Accommodation
What it is	A way of planning lessons with built-in options	A specific change for one student
Who it is for	All students in the class	The student named in the IEP or 504 plan
Basis	A research-based instructional framework, not a legal requirement	IDEA or Section 504; the IEP team decides
Who decides	The teacher or teaching team	The IEP or 504 team, with the parents
When it is decided	At lesson and unit planning	At the IEP meeting, before instruction
Where it is documented	Lesson plans, unit plans	The IEP accommodations section and the testing page
Can the teacher change it?	Yes	No, only the team can change it
Example	All students may listen to the chapter or read it	The student gets text-to-speech for all content texts over 1 page
Effect on state tests	None by itself	Testing accommodations must follow the state's allowed list
Accountability	Instructional quality	The school must provide it; parents can raise it if it is missing

The IRIS Center's UDL module shows how to build goals, materials, methods and assessments with options from the start.^[2]

Examples by subject

Subject	UDL version for the class	Accommodation version for one student
Reading	Every student may use the class audiobook for the novel	Text-to-speech for all assigned novels, loaded by the case manager
Writing	Students may plan with an organizer, a list or a sketch	A graphic organizer with sentence starters for every essay
Math	A formula sheet is posted for all students during practice	A personal formula sheet on tests that do not assess formulas
Science	Lab steps are shown in writing and pictures for the class	A checklist of lab steps at the student's station, checked off by a para
Social studies	Choice of a poster, essay or recorded talk for the unit project	Recorded talk instead of a written essay on all major projects
Testing	Quiet music-free room for all test days	Separate room with 5 or fewer students and time and a half

The right column is what goes in the IEP. The left column is good teaching that may make the right column smaller.

Three classroom scenarios

A 3rd grader and the class audiobook

Ms. Rivera's class can listen to the read-aloud of the weekly story on tablets. Sam, who has dyslexia, uses it every week. His IEP does not mention it. In March a substitute takes the tablets away.

Answer: that is UDL, so no rule was broken. But if Sam needs audio access to get to grade-level content, the team should write it as an accommodation, so it does not depend on one teacher's plans. See accommodations for dyslexia for wording.

A 7th grader with extended time

Every student in Mr. Patel's science class may finish a quiz at lunch. Kira's IEP gives her time and a half on tests. Mr. Patel says she already has extra time, like everyone.

Answer: Kira's accommodation still applies. Offering more time to everyone is UDL, but her accommodation has a set amount that the teacher must provide whether or not the class option exists. If lunch is not enough to reach time and a half, she gets more. The guide to testing accommodations covers how timing rules carry over to tests.

A 10th grader and project choice

All students in English may choose an essay or a podcast for the unit project. Devon's IEP says he may give oral responses instead of written essays on major projects.

Answer: here the UDL option already meets the accommodation. Devon picks the podcast. The teacher still records it as provided. If the next teacher does not offer choice, Devon still gets the oral option, because it is written for him.

When you need both

Most students with IEPs need both. UDL handles the options many students use. Accommodations handle the specific, required changes for one student. A practical order:

Plan the unit with UDL options for the class.
Read each student's IEP accommodations and check which the UDL plan already covers.
Add what is missing for each student.
Record that each accommodation was provided, even when it came through a class option.

For writing accommodations clearly, see how to write accommodations, and for the changes that go further, accommodations vs modifications. The list of IEP accommodations groups options by need area.

Common mistakes

Weak: "Student will receive UDL supports." Better: list the specific accommodation with what, when, how much and who.
Weak: dropping an IEP accommodation because the class already has options. Better: check that the class option fully meets the written accommodation.
Weak: writing every class option into every IEP. Better: write only what the student needs to access the work, so the list stays short enough to carry out.

Frequently asked questions

Can UDL replace IEP accommodations?

No. UDL can reduce how many accommodations a student needs, but anything written in the IEP must still be provided. Only the IEP team can remove an accommodation.

Is UDL required by IDEA?

IDEA itself does not require teachers to use UDL. Federal education law mentions it in other places, and many states and districts encourage it, but the binding duty for a student with an IEP is the IEP itself.

Should UDL options be written in the IEP?

Only when the student needs them to access the work. If the student relies on an option every day, write it as an accommodation so it does not depend on one teacher's lesson plan.
