This study aimed at identifying the relation of organizational climate and its dimensions from the PMCO measuring test for organizational climate (Cardenas & Villamizar, 2008, as cited in Cardenas, Arciniegas y Barrera, 2009) - in knowledge-sharing behavior, which was measured from the psychosocial variables and organizational conditions of knowledge-sharing behavior test (Castañeda y Fernandez, 2007). 100 participants from two types of organizations participated on this study: one of private nature and one public. A correlation of 0.578 between organizational climate and knowledge-sharing behavior was found. When carrying out an analysis of each organization, it was evident that the level of correlation between climate and knowledge-sharing behavior was highly significant in the public organization: There was a reliability level higher to 99%. There was no correlation found between the two variables studied in the private organization -with an r of 0.093 to 95%. As for the dimensions of climate and knowledge-sharing behavior, the results showed that in all public universities (including level of work, which got the lowest relation) these are statistically significant to 99.9%. In the private university only a relation to the personal growth dimension of 95% was found.
