Response to Intervention in New Hampshire: What RTI Is and What It Cannot Do

If your child is struggling in school and the district suggests trying "RTI" or "MTSS" before pursuing a special education evaluation, you are not being given the full picture. Response to Intervention has a legitimate place in New Hampshire's education system — but it has a hard legal boundary that many parents don't know about, and some districts exploit that gap.

What RTI and MTSS Are

Response to Intervention (RTI) and Multi-Tiered System of Supports (MTSS) are frameworks New Hampshire schools use to identify and support struggling students before they reach the threshold for a formal special education referral.

The model is organized in tiers:

Tier 1 — Universal, high-quality instruction delivered to all students in the general education classroom. Regular progress monitoring identifies students who may need additional support.

Tier 2 — Targeted, small-group interventions for students not making expected progress with Tier 1 instruction alone. Students at Tier 2 receive more frequent progress monitoring and more intensive academic or behavioral supports.

Tier 3 — Intensive, individualized interventions for students who are not making adequate progress in Tier 2. Tier 3 is the point at which a formal special education evaluation is typically considered.

In theory, RTI is a sound framework. It creates structured documentation of what interventions have been tried, how the student responded, and what data supports the decision to refer for special education evaluation. This documentation is valuable in the evaluation process itself.

The Legal Limitation: RTI Cannot Delay a Parent-Requested Evaluation

Here is the most important thing to understand about RTI in New Hampshire: a school district cannot use the RTI/MTSS framework to delay or deny a formal special education evaluation when a parent requests one, or when a disability is strongly suspected.

This is not ambiguous. Federal IDEA and NHDOE guidance are explicit on this point. A parent has the right to request a special education evaluation at any time, regardless of what tier of RTI the child is currently in. If you submit a written request for a special education evaluation, the district must respond to that request within 15 business days — they must convene a meeting to decide whether to evaluate. They cannot tell you to wait until the child has completed another semester of Tier 2 interventions.

Similarly, if a teacher, specialist, or other school personnel suspects a disability, the district has a Child Find obligation to refer the child for evaluation — they cannot hold that referral indefinitely on the basis that the child is still in Tier 2.

How Some Districts Use RTI Improperly

The problem arises when RTI becomes a waiting room rather than a support system. Some districts — particularly those with limited evaluation resources or a financial interest in minimizing IEP enrollment — cycle students through Tier 2 and Tier 3 interventions for extended periods without making a referral for evaluation, even when the student is not making meaningful progress.

The rationalization is often well-intentioned: "Let's give the interventions more time. We want to see if this approach works before we go to a full evaluation." But when this delay extends across multiple school years, it deprives the student of IDEA's protections and delays access to services they may be legally entitled to.

Under IDEA, a district that delays an evaluation when a disability is suspected may be violating its Child Find obligation, which requires the district to identify, locate, and evaluate children with suspected disabilities. A district that has documented evidence that a student is not responding to increasingly intensive interventions over multiple years has strong evidence that a disability may be present — and using that evidence to justify continued delay rather than triggering a referral is hard to defend legally.

How NH Uses RTI Data in the Evaluation Process

RTI data — specifically, the documented record of what interventions were attempted, how intensively they were delivered, and how the student responded — can be used as part of the eligibility determination process under the IDEA framework for Specific Learning Disabilities (SLD).

New Hampshire, like other states, permits the use of an RTI model to determine SLD eligibility. Under this model, a student does not need to show a discrepancy between ability and achievement (the old IQ-achievement discrepancy model) — instead, the team looks at whether the student failed to make adequate progress despite receiving high-quality, intensive intervention. Poor response to high-quality Tier 3 intervention can support an SLD finding.

This is different from using RTI to avoid evaluation. If the team uses RTI data to determine eligibility, they must have actually implemented the Tier 2 and Tier 3 interventions with fidelity and documented the results. A district cannot simply say "RTI hasn't been tried yet, so we can't evaluate" — that's using RTI as a barrier, which is prohibited.

What Parents Can Do

Request the evaluation in writing. Don't rely on verbal conversations about whether the district thinks the child is ready for evaluation. A written request creates a 15-business-day response deadline that the district must meet.

Ask for documentation of current RTI interventions. What specifically is being delivered at each tier? By whom? With what frequency? What does the progress monitoring data show? This documentation should already exist if the district is implementing RTI properly.

If the district denies the evaluation, they must provide you with a Written Prior Notice explaining their rationale. If their rationale is that the child should complete more RTI before evaluation, ask the district to cite the specific provision that permits delaying a parent-requested evaluation pending RTI completion. They cannot cite it — because it doesn't exist.

File a state complaint with the NHDOE if the district is refusing to evaluate or unreasonably delaying after a written request. The NHDOE Bureau of Special Education Support investigates these complaints and can require the district to conduct an evaluation.

RTI and Behavioral Concerns

MTSS frameworks also apply to behavioral supports, not just academics. Positive Behavioral Interventions and Supports (PBIS) is the behavioral tier system, and it operates similarly. If a student has behavioral needs that are not being addressed through Tier 1 and Tier 2 PBIS supports, the appropriate response at Tier 3 is a Functional Behavior Assessment (FBA) as part of a comprehensive special education evaluation — not indefinite continuation of Tier 2 behavioral interventions.

Behavioral failure to respond to intervention is data, just like academic failure to respond. It supports the case for evaluation, not the case for waiting.

Getting the Most Out of RTI Documentation

If your child is currently in RTI and you are considering a special education referral, ask for all existing RTI documentation before requesting the evaluation. This creates a comprehensive record that:

• Shows the types and frequency of interventions already attempted
• Documents the student's response (or lack of response) over time
• Supports your referral request with concrete data rather than general concerns
• Speeds up the evaluation process by providing the team with existing data

The New Hampshire IEP & 504 Blueprint includes a section on navigating the referral process from RTI, including the specific written request language that triggers the 15-business-day response timeline and prevents the district from treating your request as informal.
