The European School is one of nine schools in Costa Rica accredited by the International Baccalaureate Organization (IBO), a nonprofit educational foundation, based in Switzerland that has developed a academically challenging and balanced program of education stressing cultural awareness, physical well-being and moral responsibility. Its strong emphasis on the ideals of international understanding and responsible citizenship encourage IB students to become critical and compassionate thinkers, lifelong learners and informed participants in local and world affairs.
In addition to being individually guided and evaluated by their local instructors, IB students are also submitted to a series of written and oral examinations by a panel of special IB examiners selected from over 90 countries. Students achieving IB diplomas are accepted at hundreds of universities throughout the world, including some of the world's most prestigious, often on a preferential basis and with advanced standing.
Under this program, eleventh and twelfth-grade students at The European School complete studies in at least two languages, social studies (geography or history), experimental sciences (biology o chemistry), mathematics, and visual arts. To earn their diplomas, they must complete an extended essay, and two-year courses on the theory of knowledge (TOK) and Creativity, Action and Service (CAS) component.
