In some places, there have been waves of schools opening only to close again.
As the pandemic persisted, schools in some countries or jurisdictions reopened for in-person teaching, or opened for some students, while elsewhere schools have remained closed ever since with learning to greater or lesser extent taking place online or otherwise remotely. By April, an unprecedented 1.4 billion students were shut out of their pre-primary, primary, and secondary schools in more than 190 countries, in an effort to slow the spread of the novel coronavirus.
Decades of slow but steady progress in educating more children around the world abruptly ended in 2020.
