Three classes at Mont a l'Abbe school and 'a small number' of Beaulieu students are currently isolating because a staff member at each school has tested positive for coronavirus.
They're isolating until the track and trace process is finished.
A student at Mont Nicolle and another at Grainville have also tested positive, but as they haven't been at school 'for a number of days', no-one else at those schools has been told to isolate.
A member of staff at De Le Salle and St Clement's have also tested positive, but they also hadn't been in school for several days, so others at those schools are also unaffected.
St Luke's School Nursery will be closed next week (Monday 14 December-Friday 18 December) because so many of its support staff are absent.
