This three-part survey of modern foreign language certification requirements and practices, made under a contract with the United States Office of Education authorized under the National Defense Education Act of 1958, utilizes information supplied by Education Department officials on the state and municipal levels. The qualifications here reported and analyzed relate only to the foreign language concentration and do not include academic degree and professional education requirements except in the case of the certification of teachers of foreign languages in the elementary schools (FLES) when the secondary school certificate is especially endorsed for FLES by the addition of training in professional education. Inquiries concerning other information about conditions of certification may be addressed to the Certification Officers listed in this report. The total and wholehearted cooperation which I received from them in conducting this study is gratefully acknowledged.
