This brief highlights some ways teachers can intensify instruction regardless of content domain, grade level, or disability type. It focuses on intervention dosage, opportunities to respond, alignment, and transfer. The brief highlights what teachers need to know about the practice, examples of intensifying instruction for students with disabilities, and how to get started intensifying instruction.
