IEP vs 504 Plan: What’s the Difference?

Updated May 2026

When discussing an individualized education program (IEP) vs. a 504 plan, the differences come down to the level of support a student needs. Both provide accommodations for students with disabilities, but an IEP includes specialized instruction and services, while a 504 plan focuses on removing barriers, helping students access the general education curriculum.

IEP Overview: What Is an IEP?

An IEP is a working document defined under the federal Individuals With Disabilities Education Act (IDEA) that provides an educational blueprint for children with disabilities.

IEPs are created by school administrators, teachers, parents, psychologists, and other professionals and outline the milestones and goals students must attain based on their unique capabilities. Students enrolled in special education services or programs have IEPs.

IEPs are designed for students who need more than accommodations. They require specialized instruction that may change what and how they learn. Examples of IEP services include:

• Speech or language therapy
• Occupational therapy
• Adapted physical education
• Small-group or one-on-one instruction
• Modified curriculum or alternative assessments

504 Plan Overview: What Is a 504 Plan?

A 504 plan refers to Section 504 of the Rehabilitation Act of 1973 and states that any school or organization receiving federal funds is prohibited from discriminating against individuals with disabilities.

In school settings, any student with a learning disability can, for instance, sit at the front of the class, be allocated extra time to complete homework, assignments, or tests, or use learning materials in a format they understand. School administrators, teachers, parents, and specialists determine the accommodations students with disabilities receive under their 504 plan.

Unlike an IEP, a 504 plan does not change the curriculum. Instead, it ensures students have equal access to learning by removing barriers. Examples of 504 accommodations include:

• Extended time on tests and assignments
• Preferential seating
• Access to assistive technology
• Note-taking support or recorded lectures
• Breaks during instruction or testing

504 Plans vs IEPs: Understanding the Differences and Making the Right Choice

The key distinction between the two accommodations is that IEPs provide specialized instruction and services, while 504 plans provide accommodations for access.

Choose an IEP when:

• A student needs specialized instruction to make academic progress
• Their disability significantly impacts learning outcomes
• Ongoing services like therapy or a modified curriculum are required

Choose a 504 Plan when:

• A student can follow the general curriculum, but needs accommodations
• Their disability impacts access, not the ability to learn the material
• Supports like extended time or environmental adjustments are sufficient

Here’s a side-by-side look at how IEPs and 504 plans differ across key categories.

‍

What’s the Advantage of Having an IEP or 504 Plan?

IEPs and 504 plans exist to help students with disabilities — ranging from minor learning impairments to major intellectual, emotional, or physical disabilities — keep up with the curriculum and succeed in school. They allow students to thrive in a general education classroom while helping to minimize disruption to their learning.

For districts and educators, these plans also provide clarity, ensuring every student receives consistent, documented support aligned to their needs.

How To Tell if a Student Needs an IEP vs 504 Plan

To determine whether a student needs an IEP vs 504 plan, schools usually assess the child to determine which plan they qualify for based on the nature and severity of their disability or impairment.

While parents can pay for a private evaluation and present the report to the school administrator, schools are not obligated to adopt those recommendations. The school must carry out an independent evaluation of the student to determine their eligibility.

For a student to qualify for an IEP, the disability or health impairment must inhibit their ability to derive the full benefits of the education curriculum. Therefore, they would require specialized instruction.

On the other hand, to qualify for a 504 plan, the student’s disability or impairment must interfere with their ability to learn in a classroom without special accommodations that give them an equal opportunity to access learning.

What if a Parent Disagrees With the School’s Decision?

If a school finds that a student is not eligible for an IEP or a 504 plan, and the parent disagrees with this decision, they can take it up with the school district office or with various advocacy groups or organizations that deal with their state’s special education system.

What’s in an IEP?

IEPs must include information about the student and the specific educational program required to meet their unique needs. It must also include their current functional performance and academic achievement levels, describing how their disability interferes with their learning.

Who Qualifies for an IEP?

Any student with a disability who falls within one or more of the 13 categories listed in IDEA is qualified to receive free and appropriate education. These categories are:

• Autism
• Deafness
• Deaf-blindness
• Intellectual disability
• Hearing impairment
• Emotional disturbance
• Multiple disabilities
• Other health impairment
• Orthopedic impairment
• Traumatic brain injury
• Speech or language impairment 
• Specific learning disability
• Visual impairment

What’s in a 504 Plan?

There are no minimum requirements for what is or can be included in a 504 plan. Schools have the leeway to create customized accommodations that address the individual needs of students with disabilities.

Who Qualifies for a 504 Plan?

According to the provisions of section 504 of the Rehabilitation Act, any individual with a disability that significantly limits one or more of their major life activities qualifies for a 504 plan. Students with disabilities or medical needs that require specialized support from the school but not specialized instruction qualify.

Who Creates an IEP or 504 Plan?

By law, the following individuals must be involved in the creation process of an IEP:

• The student’s parent or legal guardian, teachers, and special education teacher
• A school psychologist or other professional qualified to discuss testing indicators and provide expert recommendations on test evaluations
• A representative from the local education agency 
• A translator, if required

Likewise, the following individuals must be involved in developing a 504 plan:

• The student’s parent or legal guardian, and teachers
• The school administrator
• The school nurse, counselor, or other relevant school personnel

Can IEPs or 504 Plans Be Modified?

IEPs and 504 plans can be modified to fit the student's evolving educational needs. For this to happen, different standards have to be reevaluated and reviewed.

An IEP must be updated annually to determine student needs and the type of specialized instruction required.

On the other hand, 504 plans require only periodic re-evaluation, typically every three years or so, but are often updated more frequently as a student’s needs change.

Ensure Consistent, Compliant Student Support With Centralized Management

Choosing between an IEP and a 504 plan is ultimately about matching the right level of support to each student’s needs, but managing those plans day to day is where the real challenge begins. Tracking accommodations, coordinating services, and ensuring compliance across campuses takes time most teams simply don’t have.
