This paper attempts to make clear the theory of Durand's architectural education through the analysis of his typical teaching programmes at the Ecole polytechnique on 1800, 1811 and 1832. These programmes show the progress of his ideal architectural education for all engineering students. He systematized the architectural education step by step according to the practical building construction, which emphasized the elements, parties and ensemble rather than the order, the form and the proportion etc. in the former teaching methods. His efforts to accomplish this educational system developed the different point of view which was accounted much of building composition.
