There is a raft of new regulations pertaining to schools and education in Indonesia. I do not intend to go into the politics of why or how, rather that they are now signed into law and that schools must comply. (despite the number of people who think that a bribe or work around will suffice, as they have in the past most schools are finding many aspects of these new regulations challenging)
For instance, one of the most obvious changes is that word ‘International’ is no longer permitted, as of Dec 1st 2014, for any school in Indonesia. Jakarta International School and British International School are two of the biggest, or most high profile schools, and they have already changed their names to Jakarta Intercultural School and British School, Jakarta.
In the past many schools identified as National Plus schools, actually National Plus was never a legal designation and these types of schools were either National or after 2009 become International.
The new regulations allow three types of schools in Indonesia.
Embassy Schools: eg: Jakarta Japanese School or Pakistan International School. As far as I understand it, these schools may not teach Indonesian students, and are limited to students of that particular nationality only. (Hence the reason that JIS chose not to become an embassy school, despite having had 3 or 4 founding embassies.
National Schools: Schools such as SMA56 or Sekolah Cikal may be national but may still use an international curriculum, such as Cambridge, however, they must also follow the 2013 Curriculum (or the 2006 Curriculum, but that’s another political story). However, the big implication for these schools is that they will no longer be allowed to hire any expatriates. (Though, I have recently been told, though cannot confirm, a national school is allowed to hire up to 4 expatriates.)
Satu Pendidikan Kerjasama or SPK Schools: This new class of schools sort of translates to Joint Cooperation School. I personally suspect that the officials that came up with this name were thinking of a franchise school, such as Dulwich College have around Asia or a subsidiary institution such as Monash University have. However, I cannot confirm this theory.
Most of the former International and many National Plus schools have chosen or intend to chose this status. As SPK schools may hire expats (within a certain ratio, less than 70%) and may chose their own curriculum to follow, such as IB, AP or CIE) SPK schools are also must allow Indonesian students to enrol if they wish, they must provide Bahasa Indonesian and cultural lessons for expat students, religious or agama lessons, civics lessons to Indonesian students. These Indonesian students must also sit for their Ujian Nasional Examinations.
