Specially Designed Instruction in Pennsylvania IEPs: What It Means and How to Get It

"Specially designed instruction" is the phrase at the center of every IEP, and also one of the most misunderstood. Schools write it into IEP documents. Parents nod along. Then three months later, the parent discovers their child is sitting in the back of a general education classroom with a highlighter and a fidget toy — accommodations, not instruction.

Understanding what SDI actually requires is the difference between a compliant IEP and a paper one.

What Specially Designed Instruction Actually Means

Under IDEA and Pennsylvania's Chapter 14, specially designed instruction (SDI) means adapting the content, methodology, or delivery of instruction to address the unique needs of the student and to ensure access to the general curriculum. The key word is "adapting" — not accommodating, not modifying the environment, but actually changing how instruction is delivered to meet the student's specific learning profile.

Accommodations (like extended time, preferential seating, or copies of notes) do not constitute SDI. They are supplementary aids and services that help a student access the existing curriculum. SDI changes the instructional approach itself — the way the student is taught, not just the conditions under which they learn.

This matters because a student who truly requires SDI should be receiving an IEP under Chapter 14. A student who only needs accommodations may appropriately be served by a Chapter 15 Service Agreement (504 plan). If your child has an IEP, the document should identify what specialized instruction they are receiving, by whom, how often, and in what setting.

SDI Requirements in Pennsylvania

Pennsylvania's Chapter 14 requires that the IEP describe:

• The amount of time the student spends in specially designed instruction
• The specific service (e.g., reading instruction, math instruction, behavioral instruction)
• The setting (general education with support, resource room, self-contained)
• The frequency and duration

The IEP must also identify who is responsible for delivering the SDI. Paraprofessionals alone cannot deliver SDI — it must be provided by or under the supervision of a certified special education teacher.

PaTTAN, Pennsylvania's Training and Technical Assistance Network, specifies that SDI be derived directly from the student's Present Levels of Academic Achievement and Functional Performance (PLAAFP). If the PLAAFP says a student reads at a 2nd-grade level in 5th grade, the IEP should include SDI targeting the specific reading deficits identified — not just a notation that the student attends a reading group.

SDI Examples by Area of Need

What SDI looks like in practice varies by the student's disability and area of need. Here are concrete examples:

Reading (Specific Learning Disability / Dyslexia)

• Explicit, systematic phonics instruction using an Orton-Gillingham approach or equivalent structured literacy program (Wilson Reading, SPIRE, RAVE-O)
• Daily small-group decoding instruction with immediate corrective feedback
• Multisensory reading instruction incorporating visual, auditory, and kinesthetic techniques

Math (Specific Learning Disability / Dyscalculia)

• Instruction using concrete-representational-abstract (CRA) sequence
• Explicit teaching of math vocabulary and problem-solving strategies using think-alouds
• Modified pacing and targeted re-teaching of foundational number sense concepts

Written Expression (Dysgraphia / SLD)

• Explicit instruction in sentence combining and paragraph structure
• Graphic organizer scaffolding with gradual release to independent writing
• Keyboarding instruction when handwriting impairment is documented

Behavior and Social-Emotional Learning (Emotional Disturbance / Autism)

• Direct instruction in social skills using structured protocols (Social Thinking, PEERS)
• Self-regulation strategy instruction (zones of regulation, cognitive behavioral techniques)
• Behavioral instruction embedded in the IEP as SDI, separate from a BIP

Communication (Autism / Speech-Language Impairment)

• Augmentative and alternative communication (AAC) device instruction
• Direct instruction in requesting, commenting, and turn-taking in structured and unstructured settings
• Language expansion techniques used consistently by trained staff across settings

Writing IEP Goals That Reflect the SDI

The goals in the IEP must connect directly to the SDI being provided. PaTTAN's standard for a measurable IEP goal in Pennsylvania includes four required components:

1. Condition: the context in which the skill will be performed ("Given a decodable first-grade text...")
2. Name: the student
3. Behavior: the specific, observable action ("...will read aloud at 90 words per minute with fewer than 3 errors...")
4. Criteria: the mastery standard ("...on 3 of 4 consecutive weekly progress monitoring probes")

A goal that says "Student will improve reading skills" is not measurable and does not reflect SDI. A goal that specifies the grade level of the text, the target fluency rate, the error threshold, and the number of consecutive trials is measurable, and it connects directly to the structured literacy instruction that should be happening.

If the goals in your child's IEP are vague, unmeasurable, or unconnected to identifiable instructional strategies, the IEP likely does not adequately reflect SDI. That is a basis for requesting an IEP team meeting to revise the document.

When the School Offers Accommodations Instead of SDI

The most common inadequacy parents encounter: the school proposes a set of accommodations — extended time, a quiet testing environment, preferential seating — and frames this as the educational plan. For a student who only needs accommodations, this is appropriate (under a 504 plan). For a student who requires specially designed instruction, it is insufficient.

If your child has an IEP and the only services listed are accommodations, ask specifically: "What specially designed instruction is my child receiving? Who delivers it? How many minutes per week? What does that instruction look like differently from what a general education student receives?"

The answers to those questions will tell you whether your child is receiving an IEP in name only, or one that actually addresses their disability-related learning needs.

The Pennsylvania IEP & 504 Advocacy Playbook includes IEP review checklists, goal quality evaluation tools, and templates for requesting revisions when the IEP doesn't reflect meaningful specially designed instruction. Get the complete toolkit at /us/pennsylvania/advocacy/.
