The short answer

The National Clearinghouse on Autism Evidence and Practice (NCAEP) reviewed research published from 1990 to 2017 and identified 28 evidence-based practices for autistic children and youth. They include visual supports, prompting, reinforcement, social narratives, naturalistic intervention, peer-based instruction, video modeling and augmentative and alternative communication. Free AFIRM modules teach many of them.

Key takeaways
  • NCAEP identified 28 evidence-based practices.
  • They include visual supports, prompting, reinforcement and social narratives.
  • Choose practices that fit each student's goals.
  • AFIRM offers free training modules.

Where should a teacher start?

Many classrooms start with three:

  1. Visual supports: schedules, first-then boards, labels
  2. Prompting: giving just enough help, then fading it
  3. Reinforcement: noticing and rewarding what you want to see
