Almost 69 million teachers need to
be recruited around the world by 2030 if international pledges on
education are to be kept.
The biggest gaps in staffing are in sub-Saharan Africa and southern Asia.
At present, the report from the Unesco Institute for Statistic says there are about 263 million children without a primary or secondary school to attend. This includes about 25 million children who will never set foot inside a school of any kind.
Niger, South Sudan, Burkina Faso, Afghanistan, Mali and Chad were among the nations whose children were likely to spend the least time in education.
