The research from the Emory University School of Medicine in the United States tested the ability of children and teenagers aged four to 14 to do their own nasal swabs.
It found self-collected positive nasal swabs from 197 symptomatic children agreed with results from healthcare worker-collected swabs in 97.8 per cent of participants.
The study also showed the children's own negative swabs agreed with healthcare worker-collected swabs in 98.1 per cent of participants.
Younger children struggled the most, with 13 of the 24 participants aged four to five having "significant" difficulties doing their own tests.
Children eight or older were more likely to correctly self-perform the rapid tests.
Access to healthcare workers to conduct the tests on children in school settings has been limited, with researchers looking to see if children were capable of self-testing.
Meanwhile, in Australia, this week's jobs and skills summit is hoping to tackle some of the employee shortages sparked by the pandemic.
