CLIL has a long history in Luxembourg dating back to 1844 when it was first introduced. It begins at age eight with subjects first taught in German and later also in French, making it common practice rather than an exception. CLIL is offered for all students and used to teach all science and social science subjects, except at the International School and European School where only English is taught as a foreign language. Recently the Ministry of Education proposed teaching science in English but teachers were reluctant because their English proficiency is usually not as strong as their German or French. Currently, the national curriculum allows use of English documents in some classes but they are discussed in French or German.
