Purpose: The purpose of this study was to examine the relationships among supervisor support, awareness of employees' developmental needs, motivation to learn, training readiness, motivation to transfer and job performance. Design/methodology/approach: A total of 216 responses from educational organizations in the USA were analyzed using the structural equation modeling method. Findings: The findings indicate that supervisor support for training directly affected motivation to learn; both developmental needs awareness and motivation to learn had direct and significant effects on training readiness, motivation to transfer and job performance; developmental needs awareness directly affected motivation to learn; training readiness directly affected motivation to transfer. Research limitations/implications: This study investigated how supervisor support contributes to motivation, training and job performance. In addition, this study attempted to bridge the gap in the literature by investigating the relationships among supervisor support, developmental needs awareness, learning motivation, training readiness, transfer motivation and job performance. Practical implications: By conducting an initial needs assessment of participants, human resource development (HRD) practitioners can reflect on what participants want and need when designing and implementing professional development programs. HRD practitioners can also collaborate with participants' supervisors to prepare for interventions to improve the quality and practicality of existing professional development programs. Originality/value: Although the extant literature suggests that organizational support, motivation and training transfer are distinct but highly interrelated constructs; little is known about the predictive properties of a supervisor's role in the training literature. Supervisors play a crucial role in that they can influence their subordinates on whether to participate in training programs. The ability of supervisors to provide adequate support and engage in comfortable communication about training programs may lead to enhanced motivation to learn and to greater training transfer. These potentially desirable effects motivate the researchers to further explore the nature of this component and its relationship with other training outcome variables.
