The highest authority concerning school education in Chile is the Chilean Ministry of Education (Ministerio de Educación, MINEDUC). The two organizing levels are Basic Education (with grades 1G to 8G) and Middle Education (from 1M to 4M).
See here for website concerning the general curriculum and its structure.
For specific curricular documents concerning Mathematics throughout 1G-8G and 1M-4M, the basic information is available in Spanish language here.
More particularly, general didactic orientations including issues of Mathematics are available here.
Since the pandemics in 2020, the so-called “Priorización Curricular” program has been implemented all along the country in order to focus on specific aspects of the curriculum pointing toward a genuine educational reactivation.
Since 2024 the celebration of a “National Week of Mathematics” has been officially added to this program.
See this volume of the Bulletin of the Chilean Mathematics Educational Society (SOCHIEM), for a full report on the first version of this initiative here.
