The École normale supérieure is one of the most selective and prestigious French grandes écoles and a constituent college of Université PSL.
It was initially conceived during the French Revolution and was intended to provide the Republic with a new body of professors, trained in the critical spirit and secular values of the Enlightenment. It has since developed into an institution which has become a platform for a select few of France's students to pursue careers in government and academia. Founded in 1794 and reorganised by Napoleon, ENS has two main sections and a competitive selection process consisting of written and oral examinations.
