Pupils are due to head back to school over the coming days, but now it seems that some of them might not. Yesterday, the government told schools to prepare evacuation plans for buildings made with RAAC concrete. This morning, schools were instructed to close these buildings altogether. This has caused immense disruption to at least 156 schools who now have to arrange alternative provision a mere couple of days, or in some cases, hours, before their students were due to crowd their corridors.
