Specially designed instruction may include changes to the content that will be taught, changes to the methodology or instructional strategies used to support the student, and changes to the delivery of instruction. Explain how understanding the characteristics of disability eligibility categories can assist teachers in planning specially designed instruction to meet the unique needs of students.
