South Dakota Learning Disability IEP: Eligibility, Evaluation, and What Parents Should Know

Your child is struggling to read, do math, or write despite trying hard and receiving decent instruction. You've been told there might be a learning disability. Now you're trying to figure out whether your child will qualify for an IEP and what happens if the school says no. Here's how South Dakota's eligibility process for learning disabilities actually works.

What "Specific Learning Disability" Means Under ARSD

South Dakota codifies its 13 special education disability categories under ARSD 24:05:24.01. Specific Learning Disability (SLD) is one of them. Under both federal IDEA and South Dakota's administrative rules, SLD is defined as a disorder in one or more basic psychological processes involved in understanding or using language — spoken or written — that affects a student's ability to listen, think, speak, read, write, spell, or perform mathematical calculations.

Eligible areas include:

• Basic reading skills (decoding)
• Reading fluency
• Reading comprehension
• Written expression
• Math calculation
• Math problem solving
• Oral expression
• Listening comprehension

SLD does not include learning problems primarily caused by visual, hearing, or motor disabilities, intellectual disability, emotional disturbance, cultural factors, limited English proficiency, or insufficient instruction in reading or math.

That last exclusion is critical: a child cannot be found eligible for SLD if the primary cause of their academic difficulty is lack of adequate instruction. South Dakota's rules explicitly require the evaluation team to rule out this possibility before finding a child eligible. If your child attended a school with documented reading instruction failures, the district may use this exclusion — legitimately or not — to deny eligibility.

How Eligibility Is Determined: Two Approaches

South Dakota allows districts to use two methodologies for determining SLD eligibility.

1. Response to Intervention (RTI) / Multi-Tiered System of Supports (MTSS)

Most South Dakota districts use a tiered intervention model. Under this approach:

• Tier 1 is quality general education instruction for all students
• Tier 2 is targeted small-group intervention for students who aren't keeping pace
• Tier 3 is intensive individualized intervention for students who don't respond to Tier 2

SLD eligibility can be determined based on a student's lack of adequate response to scientific, research-based interventions across these tiers, combined with evaluation data in the suspected disability areas.

The risk for parents: An RTI/MTSS process can delay formal evaluation for years if a school frames every struggle as something to address at the next tier. Under IDEA, your child has the right to be referred for a formal evaluation at any point if there are indicators of a suspected disability. Sitting in Tier 2 interventions for a year while waiting to "see how they respond" is not always legally justified. If you believe your child has a disability requiring specially designed instruction, you can request a formal evaluation in writing at any time — that request triggers the 25-school-day evaluation clock regardless of what tier your child is in.

2. Severe Discrepancy

Some districts still use an IQ-achievement discrepancy model, which looks for a statistically significant gap between a student's cognitive ability and their academic performance. South Dakota permits this approach but does not require it. The discrepancy model has well-documented limitations — it tends to identify students later (after they've struggled for years) and can miss students with average or below-average IQ scores who still have a genuine processing disorder.

What the Evaluation Includes

A comprehensive SLD evaluation in South Dakota must include assessments across all areas of suspected disability — not just the one area a parent requested. The evaluation is conducted by a multidisciplinary team and typically includes:

• Cognitive assessment (IQ testing) — measures working memory, processing speed, verbal reasoning, and visual-spatial reasoning
• Academic achievement testing — standardized assessments in reading, math, and writing
• Phonological processing assessment — for suspected reading disabilities
• Observation — at least one team member must observe the student in the general education classroom
• Review of existing data — grades, curriculum-based measures, intervention data, attendance records
• Parent and teacher input — interviews or rating scales

The evaluation team must produce a written report that addresses the exclusionary factors (ruling out vision, hearing, insufficient instruction, etc.) and makes a determination as to whether the student meets SLD criteria.

The Common Denial Scenarios — and How to Push Back

"Your child doesn't show a significant discrepancy." If the district is using a discrepancy model and your child's scores don't show the required gap, ask whether the district also uses RTI-based eligibility criteria. Many districts can use either approach, and RTI criteria don't require the same statistical threshold.

"The evaluation shows average scores." Average overall scores can mask significant processing weaknesses. A student can score in the average range overall but have a working memory index score in the 15th percentile and processing speed in the 10th percentile. Those intra-cognitive discrepancies matter. Request the full subtest data, not just the composite scores.

"Your child just needs more time and intervention." This is often true at Tier 1 or early Tier 2. It is not a legally valid reason to deny an evaluation once a parent has formally requested one in writing. A written evaluation request triggers the district's obligation to either evaluate within 25 school days (after consent) or provide a Prior Written Notice explaining why they are refusing — with your right to contest that refusal.

"Your child's struggles are due to insufficient instruction." Ask the district to provide their documentation for this conclusion. Under ARSD, the exclusion must be supported by specific evidence — data showing that the child received adequate, research-based instruction and that inadequate instruction is the primary cause of the difficulty.

After Eligibility: What Goes in the IEP

If your child is found eligible with SLD, the IEP must address the specific areas of the disability. For a student with a reading-based learning disability, the IEP should include:

• Measurable annual goals tied to reading fluency, comprehension, or decoding — with specific, numeric targets
• Specialized instruction in the form of an evidence-based reading program (structured literacy / phonics-based approaches have the strongest research base for reading disabilities)
• Related services if warranted — for example, speech-language services if there is a co-occurring language processing disorder
• Accommodations aligned to the disability (audiobooks, extended time, read-aloud for non-reading assessments)
• Progress monitoring data at least quarterly, with specific methodology

If the IEP team proposes goals that lack measurable targets, or "specialized instruction" that amounts to the same general education instruction with the teacher sitting closer to your child, those are quality problems worth challenging. You have the right to propose changes and to document your disagreement in writing.
