RTI and MTSS in Arkansas Schools: What They Mean for Your Child's IEP

If your child is struggling in school and a teacher mentions "RTI" or "MTSS" during a parent conference, you are standing at a fork in the road that most parents don't realize is a fork. One path leads toward special education eligibility and an IEP. The other can stretch on for months or years while your child continues to fall behind. Understanding where these systems are supposed to lead — and how they are sometimes used to delay the path you actually need — is one of the most practical things an Arkansas parent can know.

What RTI and MTSS Actually Are

Response to Intervention (RTI) is a multi-step process for providing early intervention to struggling students before or during the special education referral process. It is built on a tiered model: start with research-based instruction in the regular classroom (Tier 1), add small-group targeted intervention for students who are not making progress (Tier 2), and provide intensive individualized intervention for students who are still not responding (Tier 3).

Multi-Tiered Systems of Support (MTSS) is a broader framework that encompasses RTI for academics and adds behavioral, social-emotional, and family support components. MTSS is the term most Arkansas districts use today, with RTI folded in as the academic intervention component.

Both frameworks were designed to identify struggling students early, provide them with targeted support before they fall significantly behind, and use data from those interventions to inform decisions about whether a student may have a learning disability or other condition requiring special education.

The intent is legitimate. The problem is implementation.

How RTI/MTSS Is Supposed to Connect to Special Education

IDEA permits districts to use data from RTI processes as part of the determination of whether a student has a specific learning disability. Specifically, a student's failure to respond to scientifically based interventions can be part of the evidence base for identifying a specific learning disability (SLD) — one of the most common disability categories in Arkansas, affecting approximately 4.09% of the student population.

This means that RTI data can and should inform a special education evaluation. It does not mean that RTI is a substitute for a special education evaluation, nor that a student must complete every tier of RTI before a parent can request an evaluation.

IDEA is explicit: a parent has the right to request a special education evaluation at any time, regardless of where the child is in an RTI process. The district cannot use RTI as a reason to delay or deny that evaluation request.

How RTI Is Misused in Arkansas Schools

The most common misuse is straightforward: using RTI as an indefinite holding pattern to avoid triggering the 60-day evaluation clock.

Here is how the pattern works. A parent raises concerns about a child's academic struggles. The school acknowledges the concerns and says the student will be "placed in Tier 2 intervention" to see if additional support helps. Months pass. The parent asks for an update. The teacher says the student is making "some progress" in intervention and the team is "monitoring." More months pass. The parent eventually asks directly about special education evaluation. The school says they want to complete the RTI process before making that determination.

Meanwhile, the child's third-grade year becomes their fourth-grade year, and the gap between where they are and where their peers are continues to widen.

The legal problem with this pattern is that it treats RTI as a prerequisite for a special education evaluation. It is not. Wrightslaw and multiple federal guidance documents have confirmed this: RTI cannot be used to delay or deny a special education evaluation when there is a reason to suspect a disability. Arkansas parents have the right to submit a written evaluation request at any time — including while RTI interventions are ongoing.

A second misuse is inadequate RTI implementation itself. IDEA requires that RTI interventions be "scientifically based." A child sitting in the back of a reading group with no documented progress monitoring data is not participating in a compliant RTI process. If your school cannot produce data showing what specific intervention was used, how often, for how long, what the child's baseline was, and what progress they made at each measurement point — the RTI "process" is not meeting the standard the law requires.

What Parents Should Ask About the RTI/MTSS Process

If your child is in an RTI or MTSS intervention and you have unresolved concerns about a potential disability, get these questions answered in writing:

What specific intervention is being used and what is the evidence base for it? "We're doing extra reading practice" is not a scientifically based intervention. A district should be able to name the specific curriculum or intervention protocol (e.g., Sonday System, Wilson Reading, SPIRE, Read 180).

What does the data show? Ask for the progress monitoring data for your child across the current intervention tier. How frequently is it collected? What is the trend line? How does your child's rate of progress compare to expected benchmarks? If the school cannot produce this data, the intervention is not being implemented with fidelity.

What is the timeline? RTI interventions are not open-ended. Each tier should have a defined duration — typically 8 to 12 weeks for a Tier 2 cycle, with a data review at the end determining next steps. If your child has been "in Tier 2" for an entire school year with no clear endpoint, that is not an RTI process. It is delay.

Can I request a special education evaluation now? The answer should always be yes. If the school says no, or says you must complete the RTI process first, submit a written evaluation request immediately. At that point, the 60-calendar-day clock starts from the date the district receives your signed consent.

How to Request a Special Education Evaluation While RTI Is Ongoing

The request is simple. Put it in writing, deliver it to the special education director (not just the classroom teacher), and keep a copy.

"I am formally requesting a comprehensive special education evaluation for [child's name] under IDEA due to my concern that [child] may have a disability that is adversely affecting their educational progress. I am submitting this request regardless of the current intervention status under the school's RTI/MTSS framework."

Once the district receives a written evaluation request from a parent, they must:

1. Schedule a referral conference within 7 days
2. Hold the referral conference within 21 days
3. If evaluation is approved and parental consent is signed, complete the evaluation within 60 calendar days

The RTI process does not pause this clock and does not override the parent's statutory right to request an evaluation at any time.

MTSS and Behavioral Concerns

MTSS frameworks also apply to behavioral support, not just academics. If your child is being described as having behavioral difficulties — frequent redirections, disciplinary referrals, difficulty following classroom routines — and the school's response has been behavioral contracts or a behavior plan within the general education setting, ask explicitly whether a Functional Behavioral Assessment (FBA) under IDEA has been considered.

An FBA under IDEA is different from a general education behavioral intervention. It is a formal assessment, conducted as part of the special education evaluation process, that systematically analyzes the antecedents, behavior, and consequences to identify what the behavior is communicating and what environmental changes might address it. If the general education behavioral interventions are not working and there is reason to suspect a disability is driving the behavior, the appropriate next step is an IDEA evaluation request — not another behavior plan.

The Bottom Line on RTI/MTSS in Arkansas

RTI and MTSS are legitimate, valuable frameworks when implemented correctly. They help teachers identify struggling students early and provide targeted support. When implemented with documented data, specific evidence-based interventions, and clear timelines, they also produce useful information for special education evaluations.

But the systems are only as good as their implementation. And in practice, a substantial number of Arkansas families spend one to three years in RTI/MTSS processes that were never designed to address the level of need their child has.

If your child is not making adequate progress with intensive intervention, if concerns have been raised across multiple school years without resolution, or if there is any reason to suspect a specific disability is driving the struggle — do not wait for the RTI process to conclude. Submit a written evaluation request. The 60-day clock starts the moment the district receives your consent. That is the timeline you need to be working with.
