With the exception of English language instruction, our schools are authorized to teach the national curriculum in its three portions, primary, intermediate, and secondary. To this aim, they rely on Ministry of Education publications and general education curricula. With permission and license from the Ministry of Education, the corporation substituted a curriculum and unique books for the elementary and middle levels that were provided by The University of Cambridge. The ministry books were also updated. For primary school pupils, the schools also provide enrichment science and computing curriculum in English. The common general track is used in the secondary stage, followed by the general track for the remaining years.
