By the end of the 1960-61 school year, the National Science Foundation had provided some 75,000 opportunities for secondary mathematics and science teachers to study in its Teacher Training Programs. A study was designed in July 1961, involving questionnaires and interviews, to obtain information on non-applicants for these programs and to compare applicant-rejectees and applicant-attendees. Data were obtained concerning biographical information; professional activities, needs, attitudes, and motivations; training and education; and relevant school and community characteristics. This preliminary report was written when 1,684 questionnaires and 606 interviews (half of the expected totals) were received. The preliminary questionnaire and interview results are summarized, a description of the non-applicant population is given, and experimental and analytical procedures are described. An appendix presents the classification system used to analyze the interview summaries. (Author/BB)
