With the number of students with autism and related developmental disabilities increasing and a lack of trained professionals, solutions are needed to provide training on a large scale. Alternative training approaches need to be developed so that paraprofessionals can access training in an efficient and effective way. One such possibility is online training. A multiple baseline design across participants was used to evaluate the impact of online training videos (OTV) on the implementation of mand training with three paraprofessionals in a public school setting. The three paraprofessionals were of Hawaiian ancestry, ages 32, 34, and 42 years. Three elementary aged students with autism and developmental disabilities also participated in the study. They were ages, 6, 8, and 10 years, and also of Hawaiian ancestry. All participants lived in a rural area of Hawaii. After the OTVs, the percentage of correct implementation of mand training increased for all paraprofessional participants and maintained over time. Improvements in accurate teaching were also accompanied by increases in the rate of spontaneous manding by the students. Results support the use of online training as an effective alternative to inservice training for paraprofessionals.
