Specially Designed Instruction (SDI)

Specially Designed Instruction (SDI) refers to customizing the content, methodology and/or delivery of instruction to meet the unique needs of a student with a disability.

Elements of Specially Designed Instruction

SDI involves adapting what is taught, how it’s taught, and by whom, where, and when instruction takes place to help students with disabilities access the general education curriculum. Teachers may adjust lessons, materials, or teaching methods—such as using songs, videos, or pre-teaching key vocabulary—to build understanding. These adaptations support comprehension, memory, and skill development so every student can participate and succeed in learning.
