At any level of the Public Administration, the management must be efficient and transparent, so, the general objective of this research is to verify the level of transparency of websites of the federal universities in the South of Brazil in the year of 2014 based on what the Brazilian legislation determines. Through adaptation and application of the model proposed by Nunes (2013) for measurement of the level of transparency based on the Brazilian legislation, this work seeks to providing contribution to the researches about transparency in the public sector. In the evaluation the information content, usability of the websites and data availability were considered, distributed in a set of 25 descriptors based on the Brazilian legislation. Based on the analysis made, it has been possible to find out that the group of universities analyzed showed good transparency practices. Globally three universities showed excellent transparency level; yet most universities have improvements to be made in their websites. Federal University of Santa Catarina stood out for reaching the highest transparency level among federal universities in the south. To enable the construction of a transparency map, for future works is recommended the use of the model in universities from other regions of the country.
