Specially Designed Instruction
What it means, what record to check, and what to ask next.
What SDI means in the school record
SDI means Specially Designed Instruction. In an IEP conversation, the practical question is what decision, service, support, or record this term affects for your child.
SDI is instruction adapted in content, methodology, or delivery to address unique needs resulting from a child's disability and to help the child access the general curriculum. It is one key distinction between an IEP and a plan that only provides accommodations.
Why it matters
SDI should name the skill being taught, how instruction is adapted, who provides it, and how progress is measured. If the plan only lists accommodations, ask whether direct instruction is also needed.
What to do when you see SDI
Use this when the team is listing accommodations but your child may need direct teaching adapted to disability-related needs.
Check This Record
- Find where the IEP names special education or specially designed instruction.
- Check what skill is taught, how instruction is adapted, who provides it, and how progress is measured.
- Separate SDI from accommodations, which change access but do not teach the missing skill by themselves.
Red Flags
- The IEP has accommodations but no instruction for the skill gap.
- SDI minutes are listed without a skill, method, or provider.
- The school says support happens generally but will not write it as special education.
Documents to Gather
- IEP service grid
- Present levels
- Goal pages
- Progress reports
- Lesson/intervention notes
Sample Finding
The student has executive-function accommodations, but no instruction in task initiation, planning, or self-monitoring despite ongoing missing work.
What to Write
"Please clarify what specially designed instruction is being provided, which disability-related need it addresses, who provides it, and how progress will be measured."
Who to Contact
Start with the case manager or IEP coordinator. If the term affects a 504 plan, copy the 504 coordinator; if it affects records, copy the records contact.
When to Get Local Help
Get qualified local help if this term affects discipline, safety, placement, graduation, evaluation refusal, service loss, complaint or due-process deadlines, or a state-specific timeline.
Privacy Note
Share only the IEP pages, evaluations, progress data, service logs, or school records needed for this question. Avoid broad medical history, extra student identifiers, or unrelated records when you ask for help.
