This study aims to investigate the relationship between organizational socialization and various organizational (type of university, training, work conditions, knowledge sharing) and individual (academic degree, teaching experience, length of employment at current work place, job satisfaction, commitment, self-efficacy) level factors, both factors taken together focusing on the content, context and process dimensions of socialization. For this aim, data from 737 public and private university English language instructors were collected with an inventory consisting of three parts made up of self-developed and pre-developed scales. Taking each dimension of organizational socialization as a criterion variable, three sets of predictors were defined for three separate hierarchical regression analyses. The results revealed that socialization of instructors to the organization, department, and task are significantly predicted by several organizational and individual variables. Knowledge sharing and training are the strongest organizational level predictors while job satisfaction, self efficacy for instructional strategies, and affective commitment are the strongest individual level predictors. The results suggest higher education administrators adapt organizational and individual level managerial strategies to facilitate organizational, department and task socialization in higher education organizations.
