The Basic Education Quality Challenge
In 2008, Ministers of Education from the Iberian and Latin American countries, in a meeting in El Salvador, accepted the project: "Educational Goals for 2021: The Education we want for the Bicentennial generation", which is made up of a set of 11 goals for 2021. Its objective is to offer, in the next decade, good-quality education, able to meet the social demands. Analysing each goal by itself, one can see that having every child and teenager, from 4 to 17, in school, is still a challenge to face. But to make sure they receive proper education is, no doubt, the greatest challenge. Students still learn too little during all their school life. In Brazil, for example, only 9,1% of the students who get to finish High School prove to have learned in Math what they were expected to; concerning Portuguese, this percentage gets to 25%, nothing to be proud of. For no other reason are Latin American countries repeatedly ranked in the lowest positions according to the Programme for International Student Assessment (PISA), which focus on 15-year-old students.
