In the US companies, 135 billion dollars is allocated each year for training (Patel, 2010) and most of Asian rich countries are also trying to review their educational sytems to make required changes for enrichment of economy (Kayani, 2008:3). Continuity of the training needs to use and apply a uniformed system to promote staff's satisfaction and effectiveness of training process. The aim of this paper is to design and test the Model of Learners' Satisfaction about on-the-job training courses among those staff working in National Iranian Gas Company (NIGC). Statistical population consisted of 40000 staff working in NIGC among which 384 persons were randomly selected based on multi-stage clustering sampling method. Data were obtained via two survey questionnaires (Salanova, 2009; NIGC, 2013) with highly acceptable validity and reliability (α=0.82%). Findings, based on Regression Analysis, showed that the best predictors for learners' satisfaction about OJT courses would respectively be planning and implementation, content, time, goals and priority, executive management, need assessment, way of evaluation, welfare and services, teacher's ability, facilities and equipments. Furthermore, indices of the proposed model represented the goodness fitness of the model. Finally, some required suggestions and ways were delivered. http://pubs.sciepub.com/education/3/3/9/education-3-3-9.pdf Training Courses (TC) On-The-Job Training (OJT) Learners' Satisfaction (LS) National Iranian Gas Company (NIGC)
