IEP vs 504 Plan - Kids Can Succeed Foundation

Detailed Comparison

Feature	IEP	504 Plan
Federal Law	IDEA (Individuals with Disabilities Education Act)	Section 504 of the Rehabilitation Act of 1973
Purpose	Provides specialized instruction and related services to meet the unique needs of a child with a disability	Provides accommodations to ensure a child with a disability has equal access to education
Eligibility	Child must have one of 13 specific disability categories AND need specially designed instruction as a result. Categories: autism, deaf-blindness, deafness, emotional disturbance, hearing impairment, intellectual disability, multiple disabilities, orthopedic impairment, other health impairment, specific learning disability, speech or language impairment, traumatic brain injury, visual impairment.	Child must have a physical or mental impairment that substantially limits one or more major life activities (learning, reading, concentrating, thinking, communicating, walking, etc.). Broader eligibility than IDEA.
Evaluation Required?	Yes. Comprehensive evaluation by a multidisciplinary team, at no cost to the parent. Must be completed within 60 days of consent.	Yes, but less defined. School must evaluate but there are fewer specific requirements for how the evaluation is conducted.
Written Plan?	Yes. A detailed, legally binding document with specific required components (present levels, goals, services, placement, accommodations, etc.)	Yes, but less prescriptive. Federal law does not specify a required format, though most schools use a written plan listing accommodations.
Goals Required?	Yes. Measurable annual goals with progress monitoring and reporting.	No. 504 Plans typically list accommodations only, not academic goals.
Specialized Instruction?	Yes. Can include specially designed instruction, modified curriculum, and related services (speech therapy, OT, counseling, etc.)	No. Provides accommodations and modifications to the existing curriculum, but not specialized instruction.
Related Services?	Yes. Speech therapy, occupational therapy, physical therapy, counseling, transportation, assistive technology, etc.	Limited. Can include some related aids and services, but the range is narrower.
Parent Participation	Required by law. Parents are members of the IEP team. School must ensure parent participation.	Not specifically required by federal law, though many states and schools include parents.
Review Frequency	At least annually. Full re-evaluation at least every 3 years.	Must be reviewed periodically; federal law does not specify a frequency. Many schools review annually.
Discipline Protections	Strong protections. Manifestation determination required for suspensions over 10 days. Stay-put rights apply. Functional Behavioral Assessment and Behavior Intervention Plan may be required.	Some protections. Evaluation required before a significant change in placement (including long-term suspensions). Less detailed than IDEA protections.
Dispute Resolution	Mediation, due process hearing, state complaint. Attorney fees recoverable if parent prevails.	OCR complaint, due process hearing (under Section 504). Can also file a lawsuit in federal court.
Funding	Schools receive additional federal funding through IDEA to support special education services.	No additional federal funding. Schools must provide accommodations from their existing budget.
Applies To	Public schools and charter schools. Does not apply to private schools (though children in private schools may access some services through the public district).	Any program or activity receiving federal financial assistance, including public schools, charter schools, and some private schools.

When Is Each Plan Appropriate?

An IEP May Be Better When...

Your child needs specialized instruction (not just accommodations)
Your child needs related services like speech therapy, OT, or counseling
Your child is significantly behind grade level and needs intensive intervention
You want measurable goals and regular progress monitoring
You want strong discipline protections
You want the full range of IDEA procedural safeguards
Your child has a disability that fits one of the 13 IDEA categories

A 504 Plan May Be Better When...

Your child has a disability but does not need specialized instruction
Accommodations alone are enough to provide equal access
Your child has a condition like ADHD, diabetes, severe allergies, anxiety, or a chronic health condition that affects school performance
Your child does not qualify for an IEP but still needs support
You want a simpler, less formal plan
Your child's needs are primarily about access, not about needing a different instructional approach

Pros and Cons

IEP Pros

Most comprehensive protections and services available
Legally binding document with specific, enforceable requirements
Measurable goals with progress monitoring
Access to specialized instruction, related services, and assistive technology
Strong procedural safeguards (notice, consent, dispute resolution)
Robust discipline protections
Parent is a required team member
Federal funding supports services

IEP Cons

Narrower eligibility (must meet one of 13 categories AND need specialized instruction)
More complex and time-consuming process
Some parents worry about stigma or labeling
Can feel bureaucratic and adversarial
Meetings can be long and overwhelming
The "special education" label follows the child in school records

504 Plan Pros

Broader eligibility (any disability that substantially limits a major life activity)
Simpler process, less paperwork
No special education label
Effective for students who need accommodations but not specialized instruction
Applies to a wider range of settings (any federally funded program)
Often faster to put in place

504 Plan Cons

No specialized instruction or related services (in most cases)
No measurable goals or progress monitoring required
Fewer procedural safeguards for parents
Less detailed and enforceable document
No additional federal funding to support the plan
Weaker discipline protections
Parent participation not always required
Enforcement can be more difficult

Switching Between IEP and 504

Moving from a 504 Plan to an IEP

If your child is on a 504 Plan but is not making adequate progress, you may want to request an evaluation for special education services under IDEA.

Submit a written request to the school asking for a comprehensive special education evaluation
The school must respond (either agree to evaluate or provide written notice of refusal with an explanation)
If your child is found eligible under IDEA, an IEP will be developed to replace the 504 Plan
The 504 Plan remains in effect until the IEP is finalized and implemented
You do not need to give up the 504 Plan before requesting an IEP evaluation

Moving from an IEP to a 504 Plan

This may happen if your child no longer qualifies for special education under IDEA but still has a disability that affects school performance.

This commonly occurs at the triennial re-evaluation when the team determines the child no longer needs specialized instruction
The IEP team should discuss whether a 504 Plan is appropriate before ending the IEP
You can request a 504 Plan meeting to develop the new plan
Make sure the 504 Plan includes all the accommodations your child still needs
Important: Do not let the school simply drop services without offering a 504 Plan if your child still has a disability that affects learning

Can a Child Have Both?

Generally, no. A child with an IEP does not also need a separate 504 Plan because the IEP should include all necessary accommodations and services. The IEP is the more comprehensive document. However, if a child transitions from an IEP to a 504 Plan, it is critical to ensure no gaps in support.
