South Dakota IEP Accommodations vs. Modifications: What the Difference Actually Means for Your Child

When your child's IEP lists accommodations or modifications, you're supposed to know what that means. Most parents are given a brief explanation during the meeting and then asked to sign. The distinction matters more than the two-sentence summary suggests — in South Dakota, it has direct consequences for whether your child can earn a regular high school diploma.

The Core Difference

Accommodations change how your child accesses and demonstrates learning. They do not lower the academic bar — your child is still expected to master the same grade-level content as their peers. Accommodations remove barriers caused by the disability so your child can reach the same standard.

Common examples in South Dakota classrooms:

• Extended time on tests and assignments
• Tests in a quiet, separate location
• Preferential seating near the front of the room
• Large print or audiobook versions of text
• Use of a calculator for math computation portions
• Speech-to-text software
• Frequent sensory breaks
• An abacus or multiplication chart for math
• Read-aloud for non-reading assessments

None of these change what is being learned. The grade-level standard stays the same. The accommodation just changes how your child can demonstrate that they've met it.

Modifications change what your child is expected to learn. They reduce, simplify, or alter the actual content or performance standard. A student receiving modifications is working toward different learning targets than their grade-level peers.

Examples:

• A sixth-grader reading a simplified, lower-level version of the assigned text instead of the grade-level text
• Reducing the number of math problems required while also simplifying the problem type
• Replacing a grade-level writing standard with a modified standard tied to the student's current ability level

Modifications are sometimes appropriate and necessary — particularly for students with significant cognitive disabilities who are participating in South Dakota's alternate assessment program. But modifications carry a cost that needs to be understood before they go into the IEP.

The Diploma Problem in South Dakota

South Dakota recognizes only one official high school diploma. It requires a minimum of 22 credits and a personal learning plan. Students with disabilities are held to the same requirements — but the IEP team has authority to specify how the student fulfills them.

Here's the critical rule: if modifications reduce content to the point that it no longer aligns with South Dakota state standards, the student becomes ineligible for a regular diploma.

A student who receives modifications through high school and participates in the alternate assessment (based on Core Content Connectors) is on a pathway toward a localized "Certificate of Completion" — which is not a regular diploma. A Certificate of Completion does not end the school's FAPE obligation (so the student can continue receiving transition services until age 21 or until they earn a regular diploma), but it does create real post-secondary consequences. Many employers, community colleges, and licensing programs require a regular diploma. A Certificate is not the same.

This trajectory can begin much earlier than high school. IEP modifications in elementary or middle school that route a student toward alternate assessment can establish a path that is very difficult to reverse later. Parents need to understand, when modifications are first proposed, what the downstream implications are.

What to Ask When Modifications Are Proposed

When your child's IEP team proposes a modification — not just an accommodation — ask these questions in the meeting and request written answers:

1. Is this change to what my child learns, or just how they access or demonstrate learning? (Establishes whether it's an accommodation or modification)
2. If this is a modification, will it affect my child's alignment with South Dakota state standards in this subject?
3. What is the team's expectation regarding the regular diploma pathway for my child?
4. Is there an accommodation that could achieve the same support without modifying the content standard?
5. If we implement this modification, what data will we collect to determine whether it remains necessary, and how often will we review it?

These questions are not adversarial — they're exactly the kind of substantive engagement the IEP process is designed to support.

Accommodations on State Tests

South Dakota uses the Smarter Balanced Assessment (SBA). If your child needs testing accommodations, they must be documented in the IEP and must be "used regularly during standard classroom instruction" — not just applied on test day. This is South Dakota's consistency requirement under the SD Tools, Supports, and Accommodations (SD-TSA) policy.

Accommodations that require IEP documentation for state testing include:

• American Sign Language (ASL) interpretation
• Braille
• Read-aloud for reading passages (this one requires specific IEP documentation and eligibility criteria)
• Print-on-demand
• Abacus

If your child uses extended time, a calculator, or a text-to-speech tool every day in class, it should be in the IEP and should be the same tool used on the SBA. A discrepancy between classroom practice and testing accommodations is worth flagging.

Section 504 Accommodations: A Different Track

Students who have a disability that "substantially limits a major life activity" but do not require specialized instruction are often placed on a 504 Plan rather than an IEP. A 504 provides accommodations but no modifications — because the student is accessing the standard curriculum and just needs the barrier removed.

Common 504 accommodations in South Dakota schools for students with ADHD, anxiety, or medical conditions include: extended time, frequent breaks, preferential seating, access to water or snacks, reduced-distraction test environments, and advanced notice of schedule changes.

The difference in enforcement matters: IEP implementation failures are handled through the SD DOE Special Education Programs dispute resolution process. Section 504 grievances go to the school's internal 504 Coordinator and ultimately to the federal Office for Civil Rights (OCR). If a school is failing to implement a 504 Plan consistently, you report to the OCR, not the state complaint process.
