“…Studies have generally shown that grade retention is more likely to occur in male (e.g., Jimerson et al, 1997 ; Chen et al, 2010 ; Huang, 2014 ; Klapproth and Schaltz, 2015 ; Davoudzadeh et al, 2015 ), young-for-grade children (see Huang, 2014 ), from low socioeconomic status (e.g., Davoudzadeh et al, 2015 ; Klapproth and Schaltz, 2015 ), and being from an ethnic minority (e.g., Klapproth and Schaltz, 2015 ). Retention is also more likely when the students’ parental education level is low, mothers have a lower IQ (e.g., Jimerson et al, 1997 ; Jimerson et al, 2006 ) and parents are less involved in school life (e.g., Jimerson et al, 1997 ).…”
