In 1991, four more universities were created in the suburbs of Paris, reaching a total of seventeen public universities for the Paris (Île-de-France) région. These new universities were given names (based on the name of the suburb in which they are located) and not numbers like the previous thirteen: University of Cergy-Pontoise, University of Évry Val d'Essonne, University of Marne-la-Vallée, Ecole supérieure Robert De Sorbon and University of Versailles Saint-Quentin-en-Yvelines.
• Grandes écoles
The Paris region hosts France's highest concentration of the prestigious grandes écoles – specialised centres of higher-education outside the public university structure. The prestigious public universities are usually considered grands établissements. Most of the grandes écoles were relocated to the suburbs of Paris in the 1960s and 1970s, in new campuses much larger than the old campuses within the crowded city of Paris, though the École Normale Supérieure has remained on rue d'Ulm in the 5th arrondissement. The Paris area has a high number of engineering schools, led by the prestigious Paris Institute of Technology (ParisTech) which comprises several colleges such as École Polytechnique, École des Mines, Télécom Paris, Arts et Métiers, and École des Ponts et Chaussées. There are also many business schools, including INSEAD, ESSEC, HEC and ESCP Europe. Although the elite administrative school ENA has been relocated to Strasbourg, the political science school Sciences-Po is still located in Paris' Left bank 7th arrondissement.
The grandes écoles system is supported by a number of preparatory schools that offer courses of two to three years' duration called Classes Préparatoires, also known as classes prépas or simply prépas. These courses provide entry to the grandes écoles. Many of the best prépas are located in Paris, including Lycée Louis-le-Grand, Lycée Henri-IV, Lycée Saint-Louis, Lycée Janson de Sailly, and Lycée Stanislas. Two other top-ranking prépas (Lycée Hoche and Lycée privé Sainte-Geneviève) are located in Versailles, near Paris. Student selection is based on school grades and teacher remarks. Prépas are known to be very demanding in terms of work load and psychological stress.
