Data were gathered from members of a large professional training organization regarding their practices for supporting training transfer. Transfer factor categories grounded in the literature were used to code the data using content analysis procedures. Commensurate with the transfer literature, results suggest that trainers reported strategies used within the training setting and in the work environment as having the most influence on training transfer. Transfer practices that do not have a firm grounding in the research but that emerged in the data, trainer characteristics and evaluation practices, were reported by trainers as being important influences on training transfer. This study extends previous work on training transfer practices by elucidating the specific transfer influences perceived by training professionals as critical for supporting transfer in organizations. Implications for practice and research are offered that focus on building trainer proficiency for training transfer in organizational settings. (Contains 1 table.)
