“…The evidence put forward has been drawn from research studies of children's behaviour such as Meltzer et al (2000), McCulloch et al (2000), McLeod and Kaiser (2004), McLeod and Fettes (2007) and Ermisch (2008), from research into how schools can be successful in disadvantaged areas (Mongon and Chapman 2008b;Leadbetter 2008), from analysis of administrative attainment and exclusion data (NAO 2003;DCSF 2008bDCSF , 2008cDCSF , 2008dHansard 2007), and from studies showing how groups of learners may be affected by behaviour in a number of learning contexts (Willis 1977;Banks et al 1992;Gates, Coward, and Byrom 2007;Dunne and Gazeley 2008;Hempel-Jorgensen 2009). There can be little doubt that average educational attainment is lower in areas of concentrated disadvantage, that difficult behaviour can affect others' learning, and that behavioural and mental disorders are more common amongst the socio-economically disadvantaged.…”
