Ddydd Llun, 4 Medi, cadarnhawyd y byddai dwy ysgol ar Ynys Môn, sydd â RAAC yn eu hadeiladau, yn cau dros dro er mwyn gallu cynnal archwiliadau diogelwch pellach. Yn dilyn camau rhagweithiol ar ran y ddau bennaeth, mae Ysgol David Hughes wedi ailagor yn ddiogel i bob dysgwr, ac mae Ysgol Uwchradd Caergybi wedi gallu agor yn rhannol i ddisgyblion, gan ddarparu gwersi wyneb yn wyneb i bedwar grŵp blwyddyn ar y tro, am yn ail â’i gilydd, ochr yn ochr â thri grŵp ysgol a a fydd yn cael gwersi ar-lein.
On Monday 4 September, we confirmed that two schools in Ynys Mon, which have RAAC present in their buildings, would close temporarily to enable further safety inspections to be carried out. Following proactive management by both headteachers, Ysgol David Hughes has safely reopened to all learners and Ysgol Uwchradd Caergybi has been able to partially open for pupils with face-to-face lessons for four school year groups, alternating with three school groups, with the group not at school on any one day receiving online learning.
