This study evaluated the effects of a staff training package on the frequency (rate) of trial presentations to children diagnosed with autism. The training consisted of a combination of repeated timings, modeling plus frequency building, and modeling in vivo with the client plus frequency building. The experimenters implemented 20-min training sessions or frequency-building sessions with staff that used 1-min timings for trial presentation in each phase. Training resulted in a higher frequency of trials across all 3 participants in the modeling and feedback phase.
