Response to Intervention (RTI)
A multi-step approach schools use to identify and support students with learning difficulties. Students receive increasingly intensive levels of instruction and are monitored for progress. RTI data can be part of the evaluation process.
Federal rule: 34 CFR § 300.307 — Specific learning disabilities
Where RTI shows up in your IEP
RTI rarely has a page of its own. It turns up inside the evaluation report or the present levels narrative as tier names, intervention logs, and progress graphs from the months before the referral. Look for a phrase like "Tier 2 small group" with a start date, a weekly minutes figure, and a chart of scores underneath it.
What to ask at the meeting
- How many weeks of intervention data do you have, and may I see the graph?
- Which tier was my child in, how often did it happen, and who delivered it?
- If we start an evaluation now, what happens to the intervention while we wait?
Red flags
- Your written request for an evaluation comes back as more weeks of intervention and no consent form.
- The intervention is named but carries no start date, no minutes, and no scores beside it.
- A tier change is recorded, yet the graph underneath it stops months before the meeting.
Example
Elias spent eighteen weeks in a Tier 2 reading group. His weekly scores climbed for six weeks and then flattened, a pattern his mother could see on the graph at a glance. She asked for an evaluation in writing that afternoon. The small group kept running while the assessment went forward, and those eighteen weeks of data became part of the eligibility file.
Common questions
Does my child have to finish RTI before an evaluation can start?
No. You may request an evaluation at any point, and tiered intervention is not a reason to postpone one (§ 300.301(b); § 300.309(c)). States must allow a response-to-intervention process as part of how a specific learning disability is identified (§ 300.307), but that runs alongside your request rather than instead of it.
Is intervention data enough on its own to decide eligibility?
It is one source among several. The team still needs assessments covering every area of suspected disability, along with observations and your own account of what you see at home. Graphs show how your child responded to good teaching, which is useful context rather than a verdict.
What if the intervention seemed to be working?
That is worth celebrating and worth writing down. Ask which strategy produced the gain and where it is carried forward next year, because a support that quietly disappears in September often takes the progress with it.

A framework schools use to provide different levels of support to all students based on their needs. It includes academic and behavioral support, getting more intensive at each tier.
Evaluation
A comprehensive assessment to determine if your child has a disability and qualifies for special education. It looks at all areas of suspected disability and must use multiple methods, not just a single test.
Intervention
A targeted strategy, program, or service designed to help a student improve in a specific area. Interventions are based on the child's identified needs and are monitored for effectiveness.
