QUESTIONNAIRE DATA FROM A STUDY OF THE IMPACT OF NDEA LANGUAGE INSTITUTES ON PARTICIPANTS WERE SUMMARIZED. INCLUDED WERE THE RATINGS GIVEN BY THE PARTICIPANTS FOR THE INSTITUTE INSTRUCTION AND FOR THEIR PREVIOUS COLLEGE TRAINING, AND REPORTED STRENGTHS AND WEAKNESSES OF THE INSTITUTE PROGRAM. RATINGS FOR INSTRUCTION IN LISTENING COMPREHENSION, SPEAKING, READING, WRITING, LINGUISTICS, CULTURE, LABORATORY, AND METHODS WERE SUMMARIZED IN STATISTICAL TABLES AND WERE INTERPRETED. ALSO REPORTED WERE THE WAYS IN WHICH THE INSTITUTE EXPERIENCE RESULTED IN THE PROFESSIONAL ADVANCEMENT OF THE PARTICIPANTS.
