The society expanded slowly during the next fifteen years but enjoyed renewed interest after World War II. In 1949 the American Association of Teachers of French (AATF) endorsed the Society officially as the only collegiate French honor society in the United States. The society was admitted to membership in the Association of College Honor Societies in 1967. It currently numbers more than 380 chapters established at representative public and private colleges and universities in almost every state, as well as chapters in Paris and Aix-en-Provence.
