Cuban education continues to arouse interest and controversy not because it has been a total failure but because it can lay serious claim to considerable success. The Cuban government, of course, is in no doubt that the educational advances made since 1959 represent one of the major triumphs of the regime; indeed, Cuba's educational achievements are being used to advertise the Revolution as a whole. The success of Cuba's educational revolution is seen as an especially clear illustration of the success of the Cuban Revolution as a whole, which is regarded as a continuing, unfinished process. The Cuban educational model is a representation at one and the same time of an educational system, a set of educational principles and practices, and a strategy of educational change. Grenada and Nicaragua offer the clearest illustrations of the influence of the Cuban educational model upon socialist developing states in the Caribbean region.
