“…School turnaround is part of a broader accountability policy system. Most peer-reviewed research studies address one stage of accountability or turnaround policy at a time: when and how accountability systems identify schools as low performing (Hansen, 2012;Hochbein et al, 2013); when schools are developing school improvement plans (Fernandez, 2011;Mintrop and MacLellan, 2002;VanGronigen et al, 2017); leadership and schoolwide implementation of turnaround strategies (Ainscow et al, 2006;Cosner and Jones, 2016;Giles, 2007;Hamilton et al, 2007;Herman et al, 2008); and post hoc examinations of changes in performance (Brinson and Rhim, 2009;Dragoset et al, 2017;Hamilton et al, 2013). Longitudinal studies of turnaround that examine how schools sustain or lose ground on improvements are rare (exceptions include Bellei et al, 2016;Duke and Landahl, 2010;Earl et al, 2006;Finnigan and Gross, 2007).…”
