Yn seiliedig ar ein dealltwriaeth o ble mae'r risg o drosglwyddo fwyaf, rhaid dilyn cyfyngiadau y tu allan i'r ysgol sy'n union yr un fath â'r gofynion 'Aros Gartref' sy’n berthnasol i’r boblogaeth gyffredinol yn drylwyr. Rhaid cael dealltwriaeth glir mai dim ond yn yr ysgol y mae grwpiau cyswllt ("swigod ysgol") yn berthnasol. Dylid pwysleisio pwysigrwydd osgoi trosglwyddo rhwng athrawon, yn ogystal â rhwng staff a disgyblion.
Based on our understanding of where transmission risk is greatest, out of school restrictions identical to those ‘Stay at Home’ requirements imposed on the general population, must be applied rigorously. There must be a clear understanding that contact groups ('school bubbles') only apply within the school setting. The importance of avoiding transmission between teachers, as well as between staff and pupils should be emphasised.
