The Department of Basic Education says the learning losses as a result of Covid-19 will be felt in the sector until 2030.
Department spokesperson Elijah Mhlanga said it was now mulling a decision to have all primary school pupils back at school full-time.
Currently, most schools are using the rotational system where pupils come to school a few times a week. For the days they do not attend physical classes, schools with resources use online learning platforms.
