The École Supérieure des Sciences Economiques et Commerciales (more commonly ESSEC Business School or ESSEC) is a French business and management school, with non-profit association status (French association law of 1901), founded in 1907, with its principal campus located in Cergy. It also has locations in La Défense, Rabat and Singapore, which are used in particular for the ESSEC Global BBA and ESSEC Executive MBA programs. Founded by Jesuits in response to the creation of HEC Paris, it remained independent of any chamber of commerce and industry for a long time before passing it in 1981 under the control of the Versailles, which became the CCI of Paris Île-de-France in 2013. Today, ESSEC is a member of the CY Alliance, formerly Université Paris-Seine. The ESSEC group delivers numerous training courses in administration and management, in particular through its post-preparatory class course called the "Grande École Program" conferring the master's degree. It also delivers a "BBA" (Bachelor in Business Administration), specialized masters (SM), a master's degree in business administration (MBA) and doctorates. Historical rival of HEC Paris and of ESCP Business School, it forms with the latters the group of "three Parisians", which designates the three most prestigious business schools in France. ESSEC is also regularly cited among the best business schools in France and in Europe. Source: Wikipedia (en)
