Maltreated children frequently experience academic difficulties. In the past, this has been attributed to placement instability, length of involvement with the child welfare system, and numerous other factors that disproportionately affect maltreated children. Maltreated children are also prone to emotion regulation (ER) difficulties and patterns of emotion dysregulation. Resilience (i.e., normative functioning despite having experienced maltreatment) among maltreated children is rare, particularly across multiple domains. ER has been found to predict academic performance in non-maltreated samples. In this study, the relationship between emotion dysregulation and academic performance was analyzed in a sample already at risk for academic difficulties (maltreated children). Measures of emotion dysregulation and academic performance were analyzed in a sample of maltreated children (n = 158). Linear regression analysis indicated that the absence of emotion dysregulation was significantly related to academic resilience. Late adolescence, race, and placement stability were also significantly related to academic resilience. Implications for child welfare professionals and educators of maltreated children are discussed.
