Višnjan School of Astronomy is a international program aimed for high school students (grades 8-12). Because of often foreign participants, the activities at VSA take place in English language. The selection of students is made by reviewing of their motivation letters, results achieved in competitions and letters of recommendation of their teachers. The school usually takes 8-10 days, and for the difference of similar Višnjan’s educational programs, it includes also night work and outdoor data collection (astronomical observations). To maintain high level of individual work between mentors and team members, the program is planned for 15-20 high school students in average, divided into 4-5 groups, working on interesting projects in the fields of astronomy and astrophysics.
