... Overall, most recent studies seem to show that grade retention has a negative effect on repeaters' academic achievement and a positive effect on repeaters' psychosocial functioning, accumulating altogether in a negative effect on repeaters' school career (Goos et al., 2021;Valbuena et al., 2020), the FIRST-GRADE RETENTION AND REPEATERS' SCHOOL CAREER 5 focus of this study. Looking in more detail at effects of grade retention on repeaters' school career, recent studies (Afsa, 2011;Allensworth, 2005;André, 2009;Andrew, 2014;Belot & Vandenberghe, 2014;Cockx, Picchio, & Baert, 2019;Eide & Showalter, 2001;Eren, Depew, & Barnes, 2017;Gary-Bobo, Gousse, & Robin, 2016;Geng & Rockoff, 2017;Glick & Sahn, 2010;Goos, Van Damme, Onghena, Petry, & de Bilde, 2013;Hughes, Cao, West, Smith, & Cerda, 2017;Hughes, West, Kim, & Bauer, 2017;Jacob & Lefgren, 2009;Koppensteiner, 2014;Leighton, Souza, & Straub, 2019;Lorence, 2014;Mahjoub, 2017;Manacorda, 2012;Martorell & Mariano, 2017;Mendez, Kim, Ferron, & Woods, 2015;Moser, West, & Hughes, 2012;Okurut, 2018;Ou & Reynolds, 2010;Ozek, 2015;Peterson & Hughes, 2011;Schwerdt, West, & Winters, 2017;Solis, 2018;Uysal, 2010) seem to indicate that repeaters, overall, as compared to similar non-repeaters, have a higher chance of placement in special education, track downgrading, school absences, school suspensions, school drop-out, non-entry into tertiary education, low income, public aid receipt, etcetera, with effect sizes differing, however, considerably across study characteristics (see Goos et al., 2021, online Appendix A). ...
