Bydd cyfnod o hyblygrwydd o ran cydnabod y bydd ysgolion o bosibl am ganolbwyntio ar grwpiau blwyddyn blaenoriaeth, megis y rhai sy'n newydd i ysgolion uwchradd, y rhai sy'n sefyll arholiadau yr haf nesaf neu'r rhai mewn dosbarthiadau derbyn. Bydd hyn hefyd yn caniatáu amser, hyd at bythefnos, ar gyfer unrhyw gynllunio ac ad-drefnu.
There will be a period of flexibility in recognition that schools may want to focus on priority year groups, such as those new to secondary schools, those sitting exams next summer or those in reception classes. This will also allow time, up to a fortnight, for any planning and reorganisation.
