A grande école is a specialized top-level educational institution in France and some other previous French colonies such as Morocco or Tunisia. Grandes écoles are part of an alternative educational system that operates alongside the mainstream French public university system, and take the shape of institutes dedicated to teaching, research and professional training in either pure natural and social sciences, or applied sciences such as engineering, architecture, business administration, or public policy and administration.
The Lycée Louis-le-Grand, in Paris, is one of the most famous lycées providing preparatory classes for grandes écoles. (It is on the right side of the rue Saint-Jacques; on the left is the Sorbonne.)
