Whilst it is recognised that walking routes to schools are increasing, it is not practical to undertake salting on footways, or roads, to all schools in the county. Those schools serving the highest numbers of pupils are those most likely to be serviced by scheduled bus services or high usage footways so are likely to receive pre or post salting.
Where it is felt that untreated roads or footways leading to a school (or indeed the untreated areas within the school itself) pose a significant risk to pupils, the headteacher may decide that it is a safer option to close the school during severe weather.
The headteacher will also be considering other pressures effecting the operation of the school such as advice from police or motoring organisations that journeys should not be made which will effect availability of teaching staff and other services at the school should it remain open.
