Projections of educational attainment are complementary to projections of enrolment. They give somehow the translation of projections of enrolment rates into educational levels of attainment. Population projections by level of education allow us to have a precise knowledge not only about the combined momentum of population growth and education spread but also on the actual number of in-school or potentially in-school population by levels of education and this according to some interesting scenarios. This paper shows an application of educational attainment projections at the level of thirteen world regions. It shows the challenges that will face governments and international organizations because of increasing school-age population and increases in enrollment rates. On the contrary, for those regions that are already very advanced in the demographic transition and education levels, the task of maintaining enrolment rates ore even increasing them will not be so daunting
