For schools to reopen fully there needs to be no more small bubbles. It would need to be back to full classes, full time with normal staffing.
We are a 3 form intake infant school in an old Victorian school, with little flexibility regarding classroom use, no spare capacity and a concrete playground in a slope - so can't fit any more portacabins out there either, nor is it suitable for teaching outdoors.
From u June we have invited reception back, plus the KW/vulnerable children. To do this we need double the same we'd normally have.
We have 9 classrooms and 1 spare room, plus the hall - which also doubles up, as the dining room. Previously it was also used for assemblies, PE, etc too.
From the 8th we will have 6 'half' classes of reception, using 6 rooms plus 2 rooms for KW/vulnerable. Each will have two members of staff as part of the bubble, to allow for staff to take their breaks for lunch, toilet breaks, etc. This will be for 4.5 days a week. Friday afternoons will be for PPA and cleaning.
To invite the rest of key stage 1 back we will need 18 classrooms- so 8 more than we have. Ideally, so that staff can have a break at some point, we'd need a minimum of 18 staff too. Whilst we do have more TAs than many schools not every class normally has one FT and some of our teaching staff are themselves PT. we also have 7-9 staff who,are in either the clinically vulnerable group, or have dependants at home who are shielding - so they can't yet return.
