Purpose: The purpose of this study is to augment knowledge of how work environment and personal characteristics affect intention to transfer in a work context. This study aims to investigate the factors that can influence intention to transfer training in a professional development training context. The study examined the predictive capacity of organizational support, supervisor support, training readiness and learning motivation on transfer intention among the study respondents. Design/methodology/approach: Data were collected from teachers in secondary schools in the USA. The structural equation modeling method was adopted to analyze 216 responses using a self-report survey. Findings: We found that (a) organizational support was directly associated with supervisor support for training, (b) supervisor support for training significantly influenced training readiness and motivation to learn, (c) training readiness positively affected motivation to learn, and (d) motivation to learn positively influenced intention to transfer. In addition, supervisor support mediated the relationships between organizational support and training readiness and between organizational support and motivation to learn. Training readiness linked intention to transfer and motivation to learn. Motivation to learn also played a mediating role in the relationship between supervisor support and intention to transfer. Originality/value: Our findings add to the academic work on training transfer by empirically analyzing how both the environment (e.g. organizational support) and individual factors (e.g. learning motivation) influence employees' intention to transfer. In particular, we investigated the potential impact of both organizational support and supervisory support on intentions to transfer, compared to previous studies emphasizing only supervisory support to improve training outcomes.
