CLIL (Content and Language Integrated Learning) teaching began in Italy through bilingual education programs in the Val d'Aosta region for Italian and French. The development of CLIL was later encouraged by education laws and ministerial projects in the 1990s and 2000s, which aimed to introduce the teaching of non-linguistic subjects through a foreign language. Currently, there are many ongoing CLIL programs in Italian schools, especially at the secondary level, where networks have been formed between schools and universities to conduct research and train teachers in CLIL methods.
