A study investigated the effectiveness of the Pennsylvania Governor's School for the Agricultural Sciences (PGSAS) in stimulating high school students' interest in agriculture. It explored whether PGSAS provided participants with experiences and information that expanded their knowledge of educational and career opportunities related to the science, technology, and policy of food, agriculture, and natural resources. It also studied whether the PGSAS experience provided participants with an opportunity to explore scientific concepts, interact with professional scientists, and use research techniques. A questionnaire was mailed to 313 past program participants; a 75.1 percent usable response was received. Participants rated PGSAS, father, and mother as having some influence on choice of college major; they rated psychological determinants as having a strong influence. Participants rated a person employed in the profession, PGSAS, father, and mother as having the most influence on their choice of a career. Their current perceptions of educational and career opportunities in or related to food, agriculture, and natural resources were for the most part very positive. One-fifth classified choice of majors and future career as being in or related to food, agriculture, and natural resources. Overall, participants perceived they benefited from and were satisfied with their research experience. (Appendixes include a list of 38 references, PGSAS program description, and questionnaires.)
