What does this mean for schools?

[Shakepineapple]

Trying to get my head around what the delay to reopening means for the activities that usually go ahead at the end of the summer term.
Will parents be able to attend sports days? End of term productions? Will transition days go ahead?

Our school has cancelled the year 6-7 transition day. They've said they're acting on DfE guidelines to not mix primary bubbles.
