Accommodations vs. modifications comes down to one simple difference: accommodations change how a student learns or shows what they know, while modifications change what the student is expected to learn. With an accommodation, a student with a disability works toward the same grade-level standards as classmates, just with a different route, such as extra time or audiobooks. With a modification, the content, the expectations, or the standard itself is changed, such as a shorter reading list or easier test questions.
The two words are easy to confuse, and many people think they mean the same thing. They do not. Both are tools to give students with disabilities access to school, but the difference matters because it affects grades, state tests, and in some cases the kind of diploma a student earns. Parents and teachers who understand the difference between accommodations and modifications can make better choices in the IEP meeting or 504 plan meeting.
What are accommodations?
The meaning of accommodations in school is this: a change to the way material is presented, the way a student responds, the setting, or the timing, without lowering the learning goal. The student still learns the same content and is held to the same standard as peers. An accommodation helps remove barriers caused by the disability so the student can access the grade-level curriculum and demonstrate real skills and knowledge.
A simple example: a student with dyslexia may understand a science chapter well when it is read aloud, but struggles to decode the printed text. Listening to the chapter is an accommodation. The science content is exactly the same, and the student is still expected to learn it.
What are modifications?
Modifications change the curriculum or the expectations. The student learns different material, less material, or material at a lower level than grade-level peers. A modification is used when a student cannot reach grade-level standards even with supports, often because of a significant cognitive disability, such as an intellectual disability.
For example, while the class writes a five-paragraph essay, a student with a modified assignment may write three sentences about the topic. While classmates solve multi-step word problems, a student may work on single-step addition. The goal itself has changed, not just the path to it.
The key difference: how vs. what
An easy way to remember the difference:
- Accommodation = how. Same learning goal, same standard, different way of getting there or showing it.
- Modification = what. Changed learning goal, changed content, or a lower or different standard.
Ask one question: "Is the student still expected to learn and show the same thing as everyone else?" If yes, it is an accommodation. If no, it is a modification.
The four types of accommodations
Accommodations are usually grouped into four types.
1. Presentation accommodations
These change the way information is given to the student.
- Audiobooks or text-to-speech software
- Large print, Braille, or magnified text for a student with a visual impairment
- Directions read aloud or repeated
- Written notes, outlines, graphic organizers, or a copy of the teacher's slides
- Sign language interpreter or captions for a student who is deaf or hard of hearing
2. Response accommodations
These change the way a student completes work or answers questions.
- Giving answers orally instead of in writing
- Using a scribe or speech-to-text software
- Typing instead of handwriting
- Using a calculator or spell checker when the skill being tested is not calculation or spelling
- Using an AAC device or other assistive technology
3. Setting accommodations
These change where a student learns or takes a test.
- Preferential seating, for example near the teacher or away from the door
- Testing in a small group or a separate, quiet room
- Noise-canceling headphones
- Special lighting or adapted furniture
4. Timing and scheduling accommodations
These change how much time a student gets, or when and in what order work is done.
- Extended time on tests and assignments
- Frequent breaks
- Splitting a test over several sessions or days
- Taking tests at a certain time of day when the student works best
These examples of accommodations are common, but the list is not fixed. Accommodations should match the student's specific needs, which are described in the present levels section of the IEP (the PLAAFP).
Examples of modifications
- Fewer or easier test questions, or fewer answer choices
- Shorter or simpler reading assignments at a lower reading level
- Different grading standards than classmates, such as grading on effort or on individual goals
- Reduced homework that covers only part of the content
- An alternate curriculum or learning goals based on alternate standards
- Being excused from certain parts of a project or course
Note that some supports can be either one. "Reduced number of problems" is an accommodation if the student still shows mastery of every skill (for example, doing 10 problems instead of 30 that all practice the same skill). It becomes a modification if whole skills or concepts are left out.
Effects on grades, testing, and diploma
Accommodations generally do not change what a grade means. A student who earns a B with extended time has mastered the same content as a student who earns a B without it.
Modifications can change what a grade means, because the student was graded on different expectations. Grading rules for modified work are set by schools and states, and some may note modified courses on a report card or transcript.
For state tests, students with disabilities take part in state assessments, with appropriate accommodations when needed. The IEP must state which accommodations a student will use. Students with the most significant cognitive disabilities may take an alternate assessment based on alternate achievement standards, and the IEP team must explain why the regular test is not appropriate.
The diploma question is important. In many states, a student whose courses were heavily modified or who took the alternate assessment may not earn a regular high school diploma and may instead receive a certificate or another type of diploma. Rules differ by state, so parents should ask early, ideally before high school, how modifications will affect graduation. This also connects to the student's transition plan.
Accommodations and modifications in special education: the IEP and 504 plan
Under the Individuals with Disabilities Education Act (IDEA), the IEP must include a statement of the special education, related services, supplementary aids and services, and "program modifications or supports for school personnel" that the child needs (34 CFR 300.320). It must also list any individual accommodations needed on state and district tests. The IEP can include both accommodations and modifications, along with specially designed instruction.
A 504 plan, under Section 504 of the Rehabilitation Act, is mostly used for accommodations that give a student equal access to general education. Because 504 students are usually learning grade-level content, 504 plans rarely include modifications to the curriculum. If a student needs the curriculum itself changed, that is often a sign the student may need special education and an IEP evaluation.
Supports should be written clearly and specifically. "Extended time" is vague. "1.5 times the standard time on all tests and quizzes" is clear. Clear wording helps every teacher, and the paraprofessional who may support the student, provide the right help. Accommodations and modifications also support learning in the least restrictive environment, because they often let a student stay in the general education classroom.
How to choose the right support
- Start with accommodations. They keep the student on track with grade-level standards.
- Use modifications only when the student cannot reach the standard even with accommodations and instruction.
- Review the supports at least once a year. A student may need fewer supports as skills grow, or different ones as classes change.
- Ask the student. Older students can explain what helps them, which builds self-advocacy skills.
Frequently asked questions about accommodations vs. modifications
What is the main difference between accommodations and modifications?
Accommodations change how a student learns or is tested, but the student still meets the same standards as classmates. Modifications change what the student learns or is expected to know, which lowers or alters the standard.
Do IEPs have accommodations, modifications, or both?
An IEP can have both. IEP accommodations are the most common, and modifications are added only when the student needs changed expectations. Extended time, for example, is an accommodation, while a shorter, easier test is a modification.
What disabilities qualify for accommodations?
Any disability covered by IDEA or Section 504 can lead to accommodations if it limits the student's access to learning, including ADHD, dyslexia, autism, hearing or vision loss, and health conditions.
Is a 504 plan for accommodations or modifications?
Mostly accommodations for equal access. Modifications are possible, but uncommon. A student who needs the curriculum changed usually needs an IEP under IDEA.
Do modifications affect a high school diploma?
They can. In many states, heavily modified coursework or taking an alternate assessment can mean a student earns a certificate or alternate diploma instead of a regular diploma. Check your state's rules with the IEP team.
