The on-going staff training is one of critical components for the effective programming for adolescents and adults with autism, although it is often overlooked. The available technology can be useful to improve not only productivity and organization of our daily life, but also the work performance. The purpose of this study was to examine the effectiveness of technology on performance of instructors who are working with adolescents and adults with autism. The multiple baseline treatment design was used across instructors with the age between 26-34 who had been trained on basic knowledge and extensive application of ABA principles. The data were collected 3 to 5 times per week via Bluetooth[R] and self monitoring data collection system over 2 months. The results show that Bluetooth[R] technology can be utilized for data collection effectively, and the intervention package, including immediate feedback, self monitoring, delayed feedback with video clips and graphs significantly improved staff performance across all participants. However, the videotaping sessions and the presence of supervisor have affected staff performance and the videotaped sessions were used for positive feedback instead of corrective feedback as the author indented initially.
