The "secondary school in the country" is a concept becoming a reality in revolutionary Cuba. The concept is based on Cuba's need to feed itself and on the pedagogic and ideological premises that productive work molds man, that responsible participation by youth in building a new society is achieved by association with economic and social development plans, and that education and the school have a place in the accomplishment of Cuba's modernization. The secondary school in the country is described from its initiatory phases to the present day reality of 50 existing and 83 planned schools. The curriculum, as in the other secondary schools, is both general and polytechnic. The difference is that all the "country school" pupils, mainly from urban districts, are boarders; they combine study and work systematically during the whole school year, and their basically agricultural activities always form part of an economic development plan. The principles on which these schools were founded, the school's place in the whole educational system, their internal and external governance, their curricula, the time schedule for both teachers and students, and attempts at their evaluation are all described. In conclusion, the secondary school in the country is characterized as a lever for social, economic, technological, and educational progress. (JH)
