“…Because this chapter refers throughout to the US (or American) and the UK (or British) models of school librarianship, therefore it will be useful to define these terms at the outset. The US model of school librarianship is one in which school librarians are dualqualified as teachers and librarians, have clerical support staff, and benefit from strong professional associations and robust professional standards (AASL, 2012;Callison, 2006;Knuth, 1995;Maatta, 2008;Michie & Holton, 2005;Thomas & Perritt, 2003). A significant body of research collectively called the Lance studies indicates that the US model of school librarianship improves educational outcomes: American school libraries contribute positively to student learning and attainment (Barrett, 2010;Callison, 2006;Lance, 2006;Lance & Hofschire, 2011;Lance, Welborn, & Hamilton-Pennell 1993;Lance, Rodney, & Russell 2007;Lance, Rodney, & Hamilton-Pennell 2000;Library Research Service, 2008;Lonsdale, 2003;Sinclair-Tarr & Tarr, 2007;Williams, Wavell, & Coles 2001).…”
