Idaho Specific Learning Disability Eligibility: The 2024 Rule Change and What It Means

Idaho changed how it identifies specific learning disabilities (SLD) for the 2024-2025 school year, and the change has direct consequences for children who were previously denied eligibility — and for children currently in the evaluation pipeline. If your child struggles with reading, writing, or math but was told they don't qualify for special education services, this is worth reading carefully.

What Changed and Why

Before 2024-2025, many Idaho districts primarily used a "severe discrepancy" model to identify SLD. This model looked for a statistically significant gap between a student's IQ score and their academic achievement scores. If the gap wasn't large enough — even if the child was failing and clearly struggling — they weren't found eligible.

The severe discrepancy model has been extensively criticized in the research literature. It systematically fails to identify students with high IQs who are struggling significantly in specific academic areas. It can produce perverse outcomes: a student who is bright but reading three years below grade level might not show a "severe" discrepancy because their IQ is high, making the calculated gap appear smaller. A struggling student in a disadvantaged environment might not show a discrepancy because their IQ scores are also suppressed.

Idaho's revised rules, effective 2024-2025, require districts to use:

RTI/MTSS data. How did the student respond to evidence-based interventions provided in general education? Students who don't respond to high-quality, appropriately intensive intervention — despite adequate instruction — show a pattern consistent with a learning disability.

Pattern of strengths and weaknesses (PSW) analysis. This approach examines the relationship between cognitive processing abilities (working memory, processing speed, phonological processing, executive function) and academic performance. A student might show relative cognitive strengths in some areas and significant weaknesses in specific processing domains that directly predict academic difficulties — a pattern more consistent with an intrinsic learning disability than a general instructional need.

Districts can use either approach or a combination. The severe discrepancy model alone is no longer a permissible basis for SLD identification.

The Re-Evaluation Obligation

Here is the most actionable piece for Idaho families: the Idaho SDE required districts to re-evaluate students who were denied SLD eligibility between October 2023 and March 2024 under the old severe discrepancy criteria. If your child's evaluation fell in that window and they were found ineligible, the district has an obligation to re-evaluate them under the new criteria.

Ask your district directly: "Has [child's name] been identified for re-evaluation under Idaho's revised SLD eligibility criteria? If not, when will this occur?" If the district isn't proactively reaching out to affected families, submit a written re-evaluation request that references the SDE's revised SLD criteria and the re-evaluation obligation for the October 2023-March 2024 period.

Even outside that specific window, if your child was denied SLD eligibility and you believe the denial was based primarily on a discrepancy analysis, you can request a re-evaluation now under the new criteria. You're also entitled to an IEE at public expense if you disagree with the conclusions of the previous evaluation.

RTI/MTSS: Tool or Delay Tactic?

Idaho's new SLD criteria incorporate RTI/MTSS data — but this comes with a critical legal caveat. RTI/MTSS cannot be used to delay evaluation when a disability is suspected.

The distinction matters:

• Legitimate RTI/MTSS: A student enters the multi-tier intervention system, receives high-quality instruction at increasingly intensive levels, and data is collected to determine how they respond. If a disability is then suspected based on non-responsiveness, evaluation is initiated.
• RTI as delay tactic: A student is kept in intervention for an extended period — sometimes years — without ever being referred for evaluation, despite clear non-responsiveness, parent concern, and teacher documentation of significant difficulties. The child falls further behind while the district defers the question of whether a disability exists.

Under IDEA's Child Find obligations, if a disability is suspected, the district must evaluate. "Suspected" doesn't require certainty — it means there's reason to believe a disability may be present. A child who has been in Tier 2 or Tier 3 intervention for more than a year without meaningful progress and whose parent has expressed concerns is a Child Find case.

If your child has been in intervention tiers for an extended period without an evaluation, submit a written evaluation request. Cite IDEA's Child Find requirements and state that you suspect a disability. The clock starts running from your signed consent.

What a Complete SLD Evaluation Looks Like

Idaho's current SLD evaluation should include:

Cognitive processing assessment. Not just an IQ score — a comprehensive evaluation of processing speed, working memory, phonological awareness, rapid automatized naming, and executive function using validated instruments such as the Woodcock-Johnson Tests of Cognitive Abilities, WISC-V, KTEA-3, or equivalent.

Academic achievement testing. Standardized tests across reading (decoding, fluency, comprehension), written expression, and mathematics (calculation, fluency, problem solving). The WJ-IV Achievement, WIAT-4, or equivalent.

RTI/MTSS documentation review. The evaluation team should review all intervention documentation: what interventions were used, fidelity of implementation, and the student's response trajectory.

Observation. A qualified professional must observe the student in a relevant educational setting.

PSW analysis. Identifying where the student shows cognitive processing weaknesses relative to their own strengths, and connecting those weaknesses to the academic difficulties.

If the district's evaluation addressed only some of these areas, request an IEE covering the areas that were omitted or inadequate.

Dyslexia, Dyscalculia, and Dysgraphia in Idaho

Idaho recently strengthened its dyslexia screening and intervention requirements. "Dyslexia" is recognized as a type of SLD involving deficits in accurate and fluent word recognition and decoding, typically attributable to phonological processing differences.

If your child is being evaluated for reading difficulties and the evaluation doesn't include phonological awareness testing (such as the CTOPP-2 or PAST) and a specific assessment of phonological processing as a cognitive ability, the evaluation may be insufficient to capture a dyslexia profile. Request that the evaluation include phonological processing assessment in addition to general reading achievement.

The Idaho IEP & 504 Advocacy Playbook includes a guide to understanding SLD evaluation reports, a list of the cognitive processing domains that should be assessed, and templates for requesting re-evaluation under Idaho's revised SLD criteria — designed for families navigating the updated rules without specialized knowledge.
