"It's been very stressful," Jazmyn said.

The year 8 Kingsford Smith School student and her twin brother, Ashton, are in the final group of Canberra's public school students to head back to face-to-face learning as coronavirus measures ease in the ACT.

Their older brother Cody in year 10 went back to campus last Monday, as did years 3 and 4 students. On May 18 kindergarten to year 2, year 7 and college students returned.

On Tuesday, the remaining students in years 5,6,8 and 9 returned.

"I think the staging back has been good," mum Renea Volmari said.

"It's been good for the kids. If they'd all gone back at the same time I think it would have been too chaotic."

Ms Volmari is looking forward to her kids getting back into routine, and is confident the school has cleaning and social distancing measures in place to protect them and staff.

For Justine Lennane, the decision to send her two kids, Josie and Max back to the classroom was more difficult.

The Lennane family are at high-risk for coronavirus and are among students who can opt to continue remote learning, but Ms Lennane worried with teachers focused on face-to-face classes those learning from home would be disadvantaged.

Josie and Max, in year 5 and 8 respectively, are excited to see their friends again but anxious about going back, Ms Lennane said.

"If we get more cases in the ACT, depending on how bad it was I would definitely consider bringing them back home."

Schools have adopted new practices upon reopening to handle the threat of COVID-19. Assemblies are no longer, students are encouraged to bring their own food, lunch breaks, pick up and drop off times are staggered to lessen the amount of adults on campus.

Students don't have to be physically distant from one-another but it is important for staff, Education Minister Yvette Berry told media when on-campus classes resumed.

"Young people are still able to go about as normal, but encouraging social distancing, personal hygiene and respiratory hygiene as well along the way," she said.

On Monday, Ms Berry said the transition back to campus learning had gone well.

"Teachers, cleaners, business service officers, students, P&Cs, parents and community members, unions and transport workers are adapting again to new ways of working in schools to ensure everyone stays safe," she said.

The threat of an outbreak still looms over schools, despite no active cases of COVID-19 detected in the ACT in a month.

If a case is suspected in a school, the student or teacher should be isolated and health officials alerted.

Led by the Chief Health Officer, parents would be notified and students sent home while the campus is thoroughly cleaned and contact tracing is conducted.

The Chief Health Officer would decide when it is safe to reopen the school.

There have been no cases detected in ACT schools since students returned in Term 2.

There have been several cases detected in students in NSW and Victoria. Last week two Sydney colleges were shut down after two cases were detected.
