Bilingual and multilingual education can have significant benefits for improving education quality and reducing repetition and dropout, but key implementation challenges remain: countries must ensure that there are enough trained teachers proficient in the learners’ mother tongue and that learning resources in various languages are widely available (UNESCO, 2008: 133).
