Where UNICEF works in 135 program countries, as they're called, or low- or middle-income countries, we do invest in strengthening the capacity of teachers and in hiring local teachers from the area to provide learning materials in a variety of languages, depending on the location, to enable children to learn in their mother tongue and then transition over time.
It is very challenging in some countries when you're dealing with 45 to 50 languages, but, indeed, it's absolutely critical for us to continue to strive for younger children, in particular, to learn in their mother tongue around the world.
