To the secondary teachers on here, please can I ask are your schools using different entrances for year groups and staggered start/finish times? Also stopping breaks and reducing length of lunch time? Both my kid's schools are but they are relatively small schools with no year 12/13 provision. I'm not saying these measures are going to be effective at all but just interested to know if they are unusual. I can already see problems with siblings in different year groups waiting for each other etc.
Not a teacher
School my ds goes to, around 1700 pupils, 2 ways in/out of the building. No staggering as yet, but expect more updates as they receive them.
Realistically one person positive and the whole school is at risk. Old building and the school will be one bubble. Like many secondary schools teachers teach different years. Only HoY teach their own year. Block of toilets on each floor with 4 toilets, several urinals and 5 sinks. Staff toilet every other floor. Classrooms with sinks - Art, Science, Cooking, there's a 4 or 5 each iirc. Small classroom, halls etc single file only. They at least have 2 staircases so one for up and one for down. To get to classes either on the first floor of the main building, or have to go through that to get to classes. Ground floor is admin, hall etc. First aid room is an old broom cupboard !!
Secondary I worked in - 1 entrance, around 50 pupils, and around 40 staff - admin, head, assistants, ta's, lunchtime, tech, nhs, teachers. Plus around various passenger escorts and parents/carers collecting/dropping off. Students come from several boroughs and passenger escorts and drivers drop and pick up several pupils and can realistically have pupils from 2 years all the way to 19 from at least one school.The same bus can also have students from mainstream who have sn. They stayed opened for most of the school closure, but they had no-where near even half of their students.
Even with all the extra precautions they have in place to begin with, and strict control of the bubbles, they still had to close. Once someone sneezes or coughs, that's it, it's in the air.
It school. We all know how quickly things spread in schools. They were dropping like flies closing down before the closure was announced.
