 Phase 2 of the study was completed in February 2013. This phase of the study included full product development of the online course and a randomized controlled trial comparing the online course with face-to-face CTI training provided by our partners at the Center for Urban Community Services or CUCS. Specifically, the study included 179 service providers from 19 agencies across the United States and Canada. We randomly assigned each agency to one of two study conditions: 1 online training community of practice, or 2 face-to-face training telephone coaching. After they completed the training, we examined satisfaction with the training modalities, knowledge gains and knowledge retention. We then followed agencies CTI implementation process and assessed CTI implementation readiness, experiences in implementing CTI, fidelity to the CTI model over time, and the impact of CTI implementation on the clients served by these agencies.
