The Université Paris-Saclay is community of universities and institutions.

The decision to create the Université Paris-Saclay is the culmination of a process of collaboration between its members, begun at the time of planning its installation on the Saclay Plateau site. The process benefited from fresh momentum in 2007 when topical networks of advanced research (RTRA), Triangle de la Physique and Digiteo, were created. This momentum was strengthened in 2011 by the creation of the Jacques Hadamard Mathematics Foundation and the establishment of the Paris-Saclay Campus Foundation for Scientific Cooperation. This latter institution brings together most of the members of the Université Paris-Saclay and holds the contracts of collective projects carried out within the context of the Future Investment Program (PIA), in particular, that of the Paris-Saclay Excellence Initiative (Idex) unveiled in April 2012.

Thanks to Idex, cooperation among the members, which initially mainly focused on research, gradually extended to all the fields of activity of a university: training, technology transfer, international reach, and interaction with society. Institutions that include the Paris-Saclay Idex now want to go further in cooperating and collaborating in a shared project; they are convinced that this project must be shared by a new institution, that of a community of universities and institutions, as defined in Article L. 711-2 of the Education Code.

Université Paris-Saclay brings together in a unique model a combination of independent research and educational institutions and research organizations, who have their own identity and resources and agree to coordinate their actions and to pool certain resources as part of a shared project defined and implemented jointly.

Governance model

Located in the South/South-West area sector of the Ile-de-France region, Université Paris-Saclay organizes the regional coordination of higher education and research institutions and research centers who wish it, in terms of in terms of academic provision, research and transfer strategy, as set out in Article L. 718-2 of the Education Code, in the form of the Paris-Saclay regional group comprising the member institutions of Université Paris-Saclay and associated institutions.

The creation of Université Paris-Saclay also benefited from a financial contribution for the development of the campus, located on the land of the Urban Community of the Saclay Plateau (CAPS), and the completion of a real estate project allowing the influx of new member institutions, the relocation of many research teams, and accommodation and catering for students and personnel.
