Training ROI, last stage in the training evaluation methodology, that also includes reaction, learning, behavior and results, is the object of study of this research that investigated the existing systems to measure it in the Brazilian organizations, as well as the importance of the theme. A broad revision of the literature about the existing methods to calculate Training ROI was made and resorted mainly to authors in the United States. The theoretical reference and the realization of a pretest in 2002, contributed as basis to formulate a questionnaire that evaluated the conditions and perceptions for the calculation of Training ROI in a sample of 75 Brazilian companies from various states. The qualitative analysis together with the quantitative analysis using statistical software SPSS (t test, factor reduction, clusters formation, MANOVA), concluded that few Brazilian companies apply measurement systems in Training ROI, but the perception of its importance is high. A possible example of application was identified in the Call Center of Vésper, described at the end of the research, with the interview made.
