A follow-up study and evaluation were done on the effect of an annual 4-week academically intensive program for 50 St. Louis (Missouri) area high school junior and senior students. The program consists of two summers, the first offering general scientific experience and education, and the second providing students with the chance to conduct research under the direction of a mentor scientist. The study sought information through questionnaires to 64 1992 high school graduates who had attended the program. All students responded to the survey either by mail or by telephone. Results included the following: (1) all respondents enrolled in strong academic programs on returning to high school with 45 percent of their time committed to science and mathematics classes; (2) students reported final grade point averages between 3.7 and 4.6 (honors classes often resulted in grade point averages higher than 4.0); (3) all respondents planned to attend institutions of higher education in the fall of 1993; (4) 36 respondents planned to attend Research Universities I in the Carnegie classification; (5) nearly all participants were awarded significant amounts of financial aid including scholarships from major universities; (6) all respondents indicated that the summer experience helped spark and maintain their interest in science or mathematics; and (7) 90 percent indicated they would be interested in the Institute helping them find summer work in science, mathematics, health care, or engineering.
