An École Supérieure de Commerce or ESC is a French business school at the university level.
In most instances, such a school is a private Grande École de Commerce (an elite business school) operated by a local chamber of commerce and industry, also abbreviated as Sup de Co'.
Grande Écoles de Commerce are traditionally known for producing many, if not most, of the leading French business executives and government officials.
[2] Unlike French public universities which have an obligation to accept all candidates of the same region who hold a baccalauréat, the selection criteria of grandes écoles rests mainly on competitive written and oral exams, usually undertaken by students from dedicated preparatory classes, although this is not always the case.
Some schools use an adapted version of ESC e.g. ESSEC (École supérieure des sciences économiques et commerciales).
