One way for students with disabilities to receive instructional support from someone other than the lead classroom teacher is through paraprofessionals. Paraprofessionals who are not trained properly, however, can negatively impact student success rates. One intervention that has been explored has been the use of video modeling to train staff on various instructional and behavior management strategies. The purpose of this study was to evaluate the effectiveness of using video training to teach paraprofessionals how to implement errorless learning strategies with students. The participants within this study were three female paraprofessionals that were of Caucasian, Latino, and Ukranian descent and had worked in a classroom for at least one year. The dependent variables within this study were evaluated by use of a single subject, multiple baseline design across participants. Results of this study revealed that video training with a focus on errorless learning was effective in increasing paraprofessional percent correct implementation of the strategy, as indicated by an increase in exhibition of the strategy throughout observation and generalization sessions. Paraprofessional implementation of errorless learning procedures increased from a mean of 12.5% accuracy during baseline to 84% accuracy during intervention sessions. Generalization probes maintained high accuracy rates as well, with a mean of 88% accuracy across all three participants. The social validity results provided to the participants at the end of the study indicated that all participants prefer video training over in person training.
