The aim of this work is to analyze the Gender Equality issue within the context of Intellectual capital and performances with specific reference to knowledge organizations. The final purpose of the article is to investigate the relevance of gender issues in knowledge-based organizations including universities and firms and to provide a complete mapping of IC, gender equality and performance by identifying a rich set of indicators which integrate the existing literature both published in international peer-reviewed papers and in the grey literature, e.g. practical-based reports, produced within knowledge- intensive firms. We propose a map of the indicators grouped according to the three dimensions of the IC (human capital, structural capital, relational capital).
