There is a global teacher shortage: UNESCO.

For instance, according to UNESCO, 4.4 crore additional instructors are needed to educate all of the world's children. According to the research, 9 percent of primary school teachers will abandon their employment by 2022. In 2015, the rate was only 4.5 percent. Sub-Saharan Africa accounts for one-third of the worldwide teacher shortage. If the aim of universal primary and secondary school education is to be met by 2030, 1.5 crore more teachers will be required.
