MTSS, 504, and IEP: Which One Does Your Child Need?
A plain-language map of the three main support systems schools use, when each applies, and how families can request the right one.

A practical checklist of documents, questions, and mindset to walk into the meeting prepared.
The school district arrives at the IEP meeting with a team. Teachers, an administrator, a school psychologist, sometimes a related-services provider. They have a folder of data, a meeting agenda, and a proposed plan. You arrive alone.
That imbalance is not an accident. It is built into the structure of the meeting itself. The good news is that you can close most of the gap before you sit down at the table. Here is what to bring.
Bring printed copies of these items, in a labeled folder, in this order:
These three questions, asked in this order, surface most of what families need to know:
If the team responds to any of those questions with vague language, slow down. Ask the team to put the answer in writing in the meeting minutes.
You are not at the meeting to be polite. You are at the meeting to enforce a federal civil right your child already has. Schools sometimes treat IEP meetings as collaborations, sometimes as negotiations. Approach the meeting as both. You are part of the team that makes the decision. The law explicitly says so.
A few things to do before you walk in:
Take notes by hand or on a laptop. Write down every commitment the team makes, with the date attached. If the team says "we will start a new reading intervention next week," write the date that intervention starts. If the team says "we will reconvene in 30 days to review progress," write the actual calendar date 30 days out.
If you do not understand something, ask the speaker to explain it again in plain language. The right to plain-language explanation is yours. Do not nod through a technical explanation you are not following. Every term has a plain-language version.
Within 24 hours, send the case manager an email summarizing what you understood was agreed: "Thank you for the meeting yesterday. As I understood it, the team agreed to the following commitments." Then list each one with the date attached. Close with "Please let me know if anything in this summary differs from your notes." That email creates a paper trail you can hold the team to.
If the team's written meeting summary or amended IEP disagrees with what you understood was decided, do not sign the IEP until the document matches the conversation. You have the right to take the IEP home and review it before signing.
We built a printable IEP Meeting Notecatcher that organizes everything in this post into one document you can write on during the meeting. Space for the three questions and the team's answers. A goal-by-goal tracker. A commitments table with dates. An after-meeting checklist.

If you want an expert in your corner before the meeting, our free IEP Audit walks through your specific IEP, identifies what the team may contest, and gives you a written report and a debrief call so you know exactly what to ask. It costs your family nothing.
