Pyramidal training involves a staff training approach that includes three tiers of individuals. Tier one includes a trainer with expertise and knowledge about effective training procedures. This expert may include someone internal (e.g., supervisor and training director) or external (e.g., behavioral consultant and experimenter) to an organization. Tier-one trainers prepare a subset of staff to serve as tier-two trainers. Individuals who serve as tier-two trainers are then responsible for implementing the practices taught by the expert trainer to train tier-three employees (e.g., direct care/human service staff, teachers, and paraeducators). Organizations adopting this approach can experience numerous benefits, ultimately enhancing service quality and staff performance to support individuals with autism. Nearly five decades of published research supports this model for training human service employees. This chapter highlights the relevant research supporting pyramidal staff training, discusses the benefits, and describes potential considerations—training practices, resources, conducting quality checks, and programming for sustainability—for adopting this training model.
