  • The organization employs providers who maintain the proper credentials, training, and experience to deliver a given service.
  • The organization delivers services under an educational, behavioral, or medical model.
  • The organization does NOT promote or implement unestablished services for ASD.

Components of established evidence-based services include, but are not limited to, the following:1

  • The delivery of services is guided by published research in peer-reviewed journals and in keeping with the general consensus of the related field.
  • Ongoing services are adapted as new findings are published in peer-reviewed journals.
  • Objective data are collected and used to measure progress and guide clinical decision-making for the purpose of providing effective intervention and meaningful outcomes.
