On September 8, 2003, Castro said, "In all countries, big or small, rich or poor, Cuba ranks among the best in the field of education". Cuba did reach this level at that time. In September, 2002, statistics released by international organizations such as UNESCO showed that among the seven education surveys, except one item 1 which was slightly lower than the other two countries, all other projects in Cuba ranked first, or were in the same best position as other developed countries. It is worth mentioning that Cuba has the largest number of teachers in the world, with one teacher for every 42.23 people. Denmark is second, with 53.6 people. However, in recent years, due to the poor national economic situation and insufficient education funds, education has also been adversely affected.

Education in Cuba started not too late, but it is highly concentrated in the rich. As far as the whole society is concerned, 1959 education before the revolution was very backward, and it began to develop greatly after the revolution. As early as the late19th century, Jose Marti pointed out the importance of education to national liberation and national prosperity. Castro inherited and developed Marty's educational thought. It can be seen from a series of important historical documents published by him, such as "History will acquit me", that he not only raised the development of ethnic education to the strategic height of rejuvenating the nation, but also put forward the ways and steps of educational reform and development. This has made theoretical preparations for the great development of Cuban education after the revolution.
