Mae’r Swyddfa Diogelwch Gwrthderfysgaeth Genedlaethol wedi paratoi cyngor ar gyfer ysgolion a sefydliadau addysg eraill yn y DU, ac anfonwyd y cyngor hwnnw i holl ysgolion Cymru ar 3 Chwefror 2016. Yn sgil achosion a gododd yr wythnos ddiwethaf mewn nifer bach o ysgolion yng Nghymru, aethom ati i ailddosbarthu’r canllawiau ar 26 Mai 2016 er mwyn eu hatgoffa’r ysgolion o’r angen i adolygu eu cynlluniau diogelwch i gadarnhau bod eu trefniadau yn parhau’n briodol, a’u bod wedi eu profi er mwyn sicrhau bod y staff a’r myfyrwyr yn teimlo’n barod ac yn hyderus.
The National Counter Terrorism Security Office (NaCTSO) has produced advice to schools and other educational establishments in the UK which was circulated to all schools in Wales on 3 February 2016. Following malicious hoax communications to a few Welsh schools last week, we re-issued this guidance on 26 May 2016 reminding them of the need to review their security plans to confirm that the arrangements they should already have in place are still current and have been tested to ensure staff and students are prepared and confident.
