Is the IEP process the same in every state?

The structure is. IDEA is a federal law, so every state follows the same sequence: referral, evaluation, an eligibility decision, then an IEP reviewed at least once a year. What differs is the deadlines. IDEA sets a floor of 60 calendar days from written parental consent to complete an initial evaluation, but states may set their own timeframe, and many have.

Which states count school days instead of calendar days?

Texas counts 45 school days, New York and Illinois count 60 school days, Michigan counts 30 school days, Washington counts 35 school days, and Massachusetts counts 45 school working days. Because school days exclude weekends, holidays and breaks, a school-day deadline can take considerably longer in real time than a calendar-day one.

What if my state is not listed?

Where a state has not set its own timeframe, the federal floor applies: 60 calendar days from written consent for the initial evaluation, and 30 calendar days from an eligibility finding to have the IEP in place. Confirm the current rule with your state department of education, since these are periodically revised.

Does the IEP Process Differ by State? Timelines Compared

The rights come from one federal law. The clocks do not. Here is what changes when you cross a state line, and what stays the same.

If you have ever moved states, or compared notes with a parent in another one, you have probably run into this: the process sounds identical, but the waiting is completely different. Both things are true, and the reason is worth understanding before your next meeting.

What is the same everywhere

Special education in United States public schools is governed by one federal law, the Individuals with Disabilities Education Act. Because of that, the sequence is the same in all fifty states:

Someone refers the child for an evaluation — a parent, a teacher, or the district itself
The parent gives written consent before any evaluation happens
The district evaluates and the team decides whether the child is eligible
If eligible, an IEP is written and put into effect
The IEP is reviewed at least once a year, and the child is re-evaluated at least every three years

The vocabulary is federal too. FAPE, LRE, prior written notice, and the thirteen eligibility categories mean the same thing in Oregon as in Florida. So does the right to request an evaluation in writing, and the requirement that a school explain in writing when it proposes or refuses a change.

What changes at the state line

The deadlines. IDEA sets a floor — 60 calendar days from your written consent to complete an initial evaluation — but explicitly allows a state to establish its own timeframe instead. Plenty of states have, and some of them count differently.

That last part causes the most confusion. A deadline expressed in school days excludes weekends, holidays, and breaks. Forty-five school days is roughly nine school weeks, which in practice can be three calendar months or more if it spans a winter break. A parent in Texas and a parent in Georgia can both be inside the legal timeline while waiting very different amounts of time.

Verified states only. Where a state is not listed, the federal floor applies unless that state has set its own timeframe. Confirm current rules with your state department of education.

The three deadlines worth knowing

Initial evaluation

This clock generally starts when you sign consent, not when you first raised a concern. If you asked verbally in October and signed consent in December, the timeline runs from December. That is one reason to put a request for evaluation in writing and keep a dated copy.

IEP after eligibility

Federally, the IEP must be in effect within 30 calendar days of the eligibility determination. Several states fold this into a single combined window instead, which is why the middle column above sometimes reads "within the same 60 days."

Records requests

You have the right to inspect and review your child's education records. Federally, a school must comply without unnecessary delay and in no case more than 45 days after the request — and always before any IEP meeting or due process hearing. Some states are far shorter: California gives you five business days.

Worth knowing

Exceptions exist, and they are normal.

Timelines can pause or shift for legitimate reasons — a child who moves districts mid-evaluation, repeated failures to attend an appointment, or a summer break in states that exclude it. A missed date is a reason to ask what happened, not a conclusion about anyone's conduct.

How to use this before a meeting

Knowing the number is only half of it. The useful thing is being able to place your own dates against it — when you signed consent, when the evaluation report was dated, when the meeting was held. Most parents have never written those three dates on the same page.

Questions you could ask

01 “When did the district receive my written consent, and what date does the evaluation timeline run to?”
02 “Is our state's timeline counted in calendar days or school days?”
03 “If the timeline has passed, what caused the delay and what is the new expected date?”
04 “Can I have a copy of my child's complete education records, including evaluation data?”

None of those are accusations. They are dates, and dates are the easiest thing in the world for a team to answer without anyone becoming defensive.
