The purpose of this study is to investigate the effective factors on motivation of training transfer and its prioritization using group AHP. This research has descriptive-surveying methodology. Statistical population of this study includes 360official staff of the National Petrochemical Company.186 people were selected as samples of the study by random sampling method. Data collecting instruments include 3 discrete questionnaires including effective factors on training transfer with 45 items, Holton motivations of training transfer with 4 items, and paired comparison questionnaire with 15 factors. Obtained results from Pearson test showed that there is significant relationship among self-efficacy, locus of control, opportunity to use, support of peer/supervisor, transfer climate, learners readiness, affective reactions, openness to experience, content relevance, cognitive ability, worked samples, accountability, questioning, organizational commitment, and motivation of training transfer. Obtained data from step by step regression showed that among 15 aspects of effective factors on motivation of training transfer, variables of support of supervisor predicts 0.213, opportunity to use, affective reactions, work samples presentation, openness to experience, transfer climate, and questioning predict 0.567 of motivations to training transfer. Finally, obtained results of using group AHP technique showed that support of supervisor, transfer climate, worked samples, accountability, questioning, organizational commitment, opportunity to use, learners readiness, affective reactions to training, openness to experience, self-efficacy, cognitive ability, locus of control, content relevance, and peer’s support have priorities from the first to the fiftieth on motivation of training transfer, respectively.
