“…While it has been extensively researched in the United States (Canon & Lipscomb, 2011;Hong & Raudenbush, 2005;Hong & Yu, 2008;Hughes, Chen, Thoemmes, & Kwok, 2010;Jimerson, 2001aJimerson, , 2004, it has drawn little research attention in Australia, despite it being, as McGrath (2006) suggests, 'widely accepted in Australian schools ' (p. 39). Its wide acceptance in Australian schools is of considerable concern as research has shown that it offers limited benefits for students (Canon & Lipscomb, 2011;Choi, Gil Izquierdo, Mediavilla, & Valbuena, 2018;Hatte, 2017;Hong & Raudenbush, 2005;Hong & Yu, 2006;Martin, 2011;McGrath, 2006) and may be harmful (Jimerson, 2001a(Jimerson, , 2001b(Jimerson, , 2004. To demonstrate 'the efficacy of grade retention during the past century', Jimerson in 2001 conducted a meta-analyses of three metaanalyses (Holmes, 1989;Holmes & Matthews, 1984;Jimerson, 2001a) that provided outcomes of 83 published studies between 1925-1999 (Jimerson, 2001b, p. 48).…”
