The main objective searched through this scientific contribution consists to remove certain ambiguities surrounding the concept of the performance of the public service in the Moroccan university context. The methodology adopted in this respect joins in an exploratory approach, based essentially on a thorough reading of a rich theoretical corpus relating to the higher education sector, thing which allowed us to create anastomoses between some academic writings. In this respect, our article focuses on two main axes: the first identifies certain writings relating to the term of the "performance". Indeed, this concept has flowed a lot of ink in the field of organization sciences. However, it remains complex and difficult to define, this is explained essentially by its contingent, relative, multidimensional, encompassing and integrating aspect. As for the second, we try there to elucidate the significance of the performance under its multidimensional character in the Moroccan public university. Consequently, twenty-one facets of university performance are put forward, namely: finance and economy, organization, reputation and brand image, internationalization, governance, employability- insertion, partnership, innovation and creativity, scientific research, identity, teaching and training, environment and ecology, diversification, societal performance, communication, technology, university size, entrepreneurship, conformity, extracurricular and democratization. To evaluate these performances, some performance indicators are highlighted.
