Olomouc Summer Institute (Olomoucká letní škola) is a project assembling students from all over the world each year, at the beginning of July, in Olomouc, the Czech Republic. The project began in 1994 and in a time span of 11 years it evolved continuously. Beginning with 1998, the OSI welcomed a broad contingent of international students. All of the participating students are required to take part into different educational activities that are being held in English, the official language of the program. The Classes and Seminars are dedicated to developing young leaders in order to sustain growing democratic societies. At the same time, the Olomouc Summer Institute offers to its participants exciting Special Activities, like the Leadership Challenge, which constitute the memories of a life-time for many alumni.
