A STUDY WAS MADE OF SEVEN NDEA INSTITUTES, GIVEN IN THE SUMMERS OF 1965 AND 1966 FOR UNDERGRADUATES PREPARING TO BE FOREIGN LANGUAGE TEACHERS, TO DETERMINE IF THESE INSTITUTES ARE AN EFFECTIVE SUPPLEMENT TO COLLEGE LANGUAGE PROGRAMS. INFORMATION SOURCES FOR THE STUDY WERE INSTITUTE DIRECTORS AND THEIR STAFF, VISITORS' OBSERVATIONS, AND QUESTIONNAIRES. A SUMMARY OF THE QUESTIONNAIRE DATA, RELATED TO THE INSTITUTES AND HOME CAMPUSES, IS PRESENTED UNDER THE HEADINGS LANGUAGE SKILLS, FOREIGN CULTURE, LINGUISTICS, AND METHODOLOGY. THE DATA AND THEIR IMPLICATIONS ARE ASSESSED. A SAMPLE OF THE QUESTIONNAIRE, DETAILED RESPONSE DATA, AND 22 PAGES OF FREE COMMENTS FROM THE RESPONDENTS ARE INCLUDED IN THE APPENDIXES. (SS)
