The present study investigated the effects of online Community-based Instruction (CBI) training for pre-service special education teachers in Turkey. The training consisted of three knowledge modules and skill application assignments designed to be completed in 4 weeks. Results demonstrated statistically significant difference between control and treatment groups on CBI knowledge. Further, there were significant correlations between application assignment scores and post-assessment scores, as well as on time spent online and post-assessment scores. Maintenance data collected 3 months after the training showed that pre-service teacher participants' maintained their knowledge related to CBI over time. Limitations and future directions are discussed.
