Education Minister Yvette Berry visited the school on Tuesday and said she received further advice that the situation did not pose a major health risk.

"The Education Directorate has responded to this situation in line with expert advice," she said.

Ms Berry said there were no plans to demolish any buildings and no plans to install transportable buildings.

A WorkSafe spokesperson said removal of lead-painted windows in eight classrooms in the July school holidays did not constitute a lead process as per Work Health and Safety regulations.

The spokesperson said WorkSafe was not asked for advice in this project and was not investigating any aspect of handling of lead paint at the school.

"WorkSafe ACT has received an air monitoring report from the workplace. WorkSafe is satisfied that workers were not exposed, as the air monitoring in place while the activity was being conducted, indicated dust levels were below the relevant exposure standard. As such, the work is not considered Lead Risk Work and therefore is not notifiable," the spokesperson said.

Students and staff have been barred from the affected rooms since the start of Term 3 and dozens of students have been blood-tested for lead poisoning.

Students in preschool, the Montessori school, kindergarten and year 3/4 will not be allowed into their classrooms until lead levels have been reduced by environmental cleaning.

The YWCA and Aeon Academy after school care programs have also been relocated.

The ACT Health Directorate has been contacted for comment.
