Roedd yn galonogol iawn gweld bod mwy o dystiolaeth o gysoni nag a fu ar gyfer y ddau ymarfer blaenorol ar gyfer dyddiadau tymhorau 2016/17 a 2017/18. Roedd tystiolaeth arwyddocaol hefyd o gytundeb rhwng awdurdodau lleol a'u hysgolion gwirfoddol a gynorthwyir ac ysgolion sefydledig wrth i 83 o’r 86 hysbysiad wedi'i lofnodi gan yr ysgolion hyn gytuno i gyd-fynd â'u hawdurdod, gyda'r tair ysgol arall sy’n ysgolion Catholig yn dewis aros ar agor yn ystod yr Wythnos Fawr.
I was very encouraged to see that there was greater evidence of harmonisation than there was for the previous 2 exercises for term dates for 2016/17 and 2017/18 There was also significant evidence of agreement between local authorities and their VA and foundation schools as from 86 signed notices from these schools, 83 agreed to align with their authority, with the other 3 being Roman Catholic schools who chose to remain open during Holy Week.
