This directory provides data concerning teaching staff and language programs in Illinois' schools. The publication is presented in two parts: Public Schools, and Independent, Parochial and Private Schools. Both sections present data concerning: (1) county, school and district number, name of teacher, and language(s); and (2) name of teacher, school and district number, code, county, and language(s). The "Illinois Foreign Language Directory" was compiled from a survey-questionnaire, prepared and mailed to all superintendents and principals in the Illinois' schools. (RL)
