This document tabulates and summarizes the professional qualifications, activities, and interests of applicants to institutes for high school science and mathematics teachers sponsored by the National Science Foundation in the summer of 1957 and the academic year 1958-59. All participants, all applicants who were accepted but later withdrew, and a random sample of rejected applicants approximately equal to the number of participants are included. The data are organized in 13 tables covering the following areas: academic preparation, credits and grades, major teaching fields, courses now taught, areas of professional interest, employment record, extra-curricular activities, membership in organizations, and journals read. Each area also has a brief summary and analysis. (Author/BB)
