Current structure
From birth until the age of 3, Indonesian children do not generally have access to formal education. From the age of 3 to 4 or 5, they attend kindergarten (Taman Kanak-kanak). This education is not compulsory for Indonesian citizens, as the aim of this is to prepare them for primary school. The majority of kindergartens are private schools, with more than forty-nine thousand kindergartens, 99.35% of the total kindergartens in Indonesia, privately operated. The kindergarten years are usually divided into "Class A" and "Class B" students spending a year in each class.
Children ages 6–11 attend Sekolah Dasar (SD) (literally Elementary School). This level of education is compulsory for all Indonesian citizens, based on the national constitution. In contrast to the majority of privately run kindergartens, most elementary schools are government operated public schools, accounting for 93% of all elementary schools in Indonesia. Similar to education systems in the U.S. and Australia, students must study for six years to complete this level. Some schools offer an accelerated learning program, where students who perform well can finish elementary school in five years.
