English: Yes, thank you for that question. We are content with the sample, given the size of Wales and the number of secondary schools we have. We went, in total, to 35 secondary settings. We went to at least one school in each local authority area in Wales and where there were more than nine schools, we went to a second secondary school too. So, the sample was a mix of schools where we had some information about safeguarding issues, some schools that were named in the Everyone's Invited report, and then half of them, we had no information on, it was just a sample. In terms of the number of pupils whose parents didn't want them to participate, I would think it was around six to eight children out of 1,300 children. We'd hoped to see around 1,600, but it is important that we note that we did go out in the two weeks when the number of COVID-19 cases was highest among secondary pupils in Wales, which was the last week of September and the first week of October. And I have to say that it is a cause of pride that schools and school headteachers had welcomed our request to attend schools at such a challenging time and had welcomed the work and had seen the importance of the work. So, in terms of the sample of 1,300 children, we think that's a fair sample, it's a far larger sample than the sample taken by our colleagues in Ofsted, for example, who have looked at this in a larger nation, of course. I think it is fair for us to say, Sioned, if we had chosen another 35 different schools, then I'm quite certain that the messages would have been the same in those other 35 schools. And also, the fact - and I think Dyfrig can explain a little more on this - the nature of the training and preparation given to inspectors to go into the schools had meant that we were able to create a comfortable, safe environment for young people to speak openly. And praise is due, therefore, to the inspectors first of all, but more so to the pupils for being so willing to be so open and willing to talk about sensitive and difficult issues. Thank you.
Welsh: Ie, diolch ichi am hynny. Mi ydyn ni'n hapus efo'r sampl, dwi'n meddwl, o ystyried maint Cymru a nifer yr ysgolion uwchradd sydd yna. Mi aethon ni i mewn i 35 o ysgolion i gyd, lle mae yna blant uwchradd. Mi aethon ni i o leiaf un ysgol ym mhob un awdurdod yng Nghymru a lle'r oedd yna fwy na naw ysgol yn yr awdurdod, mi aethon ni i ail ysgol uwchradd. Mi oedd y sampl yn gymysgedd o ysgolion yr oedd gennym ni ychydig o wybodaeth am faterion diogelu yn yr ysgol, ysgolion a oedd wedi'u henwi yn adroddiad Everyone's Invited, ac wedyn hanner ohonyn nhw efo dim gwybodaeth, jest sampl rhydd. O ran niferoedd y disgyblion yr oedd eu rhieni nhw ddim yn dymuno, byddwn i'n meddwl ei fod o gwmpas chwech i wyth o blant allan o 1,300 o blant. Mi oedden ni wedi gobeithio gweld tua 1,600, ond mae'n bwysig ein bod ni'n nodi ein bod ni wedi mynd allan yn y ddwy wythnos pan oedd y nifer fwyaf o achosion o COVID-19 ymysg disgyblion uwchradd yng Nghymru, sef wythnos olaf mis Medi ac wythnos gyntaf mis Hydref. Ac mae'n rhaid imi ddweud ei fod o'n destun balchder bod ysgolion a phenaethiaid wedi croesawu'r cais i ni fynd i'r ysgol mewn amser mor heriol ac wedi croesawu'r gwaith a gweld pwysigrwydd y gwaith. Felly, o ran y sampl o 1,300 o blant, rydyn ni'n meddwl bod hwnna'n sampl teg iawn, mae o'n sampl llawer mwy na sampl ein cyfeillion ni yn Ofsted, er enghraifft, sydd wedi edrych ar hyn mewn gwlad mwy o faint. Dwi'n meddwl bod o'n iawn inni ddweud, Sioned, petaem ni wedi dewis 35 ysgol arall wahanol, dwi'n sicr iawn mai yr un fyddai'r negeseuon wedi bod mewn 35 ysgol arall hefyd. A hefyd, mae'r ffaith bod - a dwi'n meddwl bod Dyfrig efallai yn mynd i egluro ychydig mwy - natur yr hyfforddiant a'r paratoad gafodd arolygwyr i fynd i mewn i'r ysgolion wedi golygu ein bod ni wedi gallu creu awyrgylch gyfforddus, ddiogel i bobl ifanc siarad. Ac mae hynny yn glod, felly, i'r arolygwyr yn y lle cyntaf, ond yn fwy na dim, i ddisgyblion yr ysgol i fod mor barod, i fod mor agored i siarad am faterion sensitif ac anodd. Diolch.
