With the 2 year groups out of 6 returning in June, we are dividing up the year groups, spreading one class between 4 rooms, providing handwashing, material packs, planning safe movement around school. Plus simultaneously providing online learning for the other year groups, and overseeing children of key workers and vulnerable students.
A September return for all year groups will not be possible if we are to meet 2 meter distancing guidelines.
Only a small proportion of students can be in school at any one time safely.
Timetabling is going to be a massive challenge.
To safely social distance in schools with old buildings and 1300+ students is not possible.
There cannot be a safe return to 31 students in a room, 5 changeovers, breaks, lunches plus the vast numbers using public transport.
There is no easy answer.
