This year group at high school and vocational colleges was the first to resume lessons across the country as part of a progressive reopening of schools.

The education ministry said that the 4% absence rate was in-line with rates recorded in non-pandemic times. It said that the majority were “vulnerable pupils”.

Schools have implemented strict protective measures to prevent the spread of coronavirus. These include social distancing, the wearing of face coverings on public transport, and stringent facility cleaning and hand washing habits. Students and staff have also been strongly encouraged to get tested for coronavirus.

Classes for the remaining years at secondary school are expected to restart on 11 May, with classes split in two and groups alternating weekly half-day attendance to reduce contact.

Primary school classes, crèches and after school facilities are expected to follow on 25 May. Canteens will be closed and sports classes cancelled until the end of the year.

Schools closed to the public from 16 March as part of measures to stop the spread of coronavirus. The reopening of schools has come up against significant resistance among parents. A public petition launched in April calling for them to remain closed until the start of the September school year has over 6,500 signatures.
