Summer schools for pupils at risk of \"going off the rails\" are being promised by the Deputy Prime Minister Nick Clegg. The £50m project, aimed at pupils about to start secondary school in England, is being announced at the Liberal Democrats\' annual conference. Mr Clegg will link this summer\'s riots to educational failure. \"Too many of these young people had simply fallen through the cracks,\" he will tell his party\'s conference. Critical leap\' Secondary schools will be asked to volunteer to hold the summer schools, which could offer a fortnight of catch-up lessons in basic skills such as literacy for 100,000 pupils. The schools could also offer sports-based holiday projects for these 11-year-olds who have just left primary school. The £50m will allow the scheme to be run for one year - with the funding drawn from the pupil premium budget, which will help schools to provide extra support for disadvantaged pupils. Mr Clegg will tell the conference that the summer schools will help children make the transition into secondary school. \"So often the people who have gone off the rails are the ones who were struggling years earlier. Not least in making that critical leap from primary to secondary school. \"We know this is a time when too many children lose their way.\" The National Association of Head Teachers (NAHT) welcomed the camps, but said they must not be seen primarily as an antidote to \"broken Britain\". General secretary Russell Hobby said: \"If what Mr Clegg has in mind are just literacy boot camps for poor children, they will squander the chance of doing something with enormous potential for all. \"Neither should summer camps be seen as \'punishment\' for children that have fallen behind or they will lose the support of the very families they seek to help. \"We\'d like to see residential schemes extended for all children at a range of locations - universities, outdoor centres and so on.\"
