The general advice for the next three weeks is that this is an extended Easter break. For secondary-age students, it would be normal to expect some independent or supported learning to take place during holidays. This is especially so for students in Years 10 and 11 (studying KS4 courses) and in post-16 studies, whether at the Sixth Form or the College of Further Education.
It is reasonable, therefore, to suggest that students should be engaged in some sort of learning activity on a daily basis. Educational research has indicated that children spending time on their school work outside of formal lessons can support their progression and achievement. This is just as true in the period of school breaks, though it is important that students ensure that they do have a rest from the previous school term and spend time with their families.
