Using national survey data, the present study investigated whether adolescents living with parents of their same gender fare better on academic achievement than their peers living with opposite-gender parents. Multiple analyses of covariance (MANCOVA) procedures were employed to examine the effects of the children's gender in single-father and single-mother families on students' academic achievement, as measured by four dependent variables (reading test score, mathematics test score, English teachers' evaluation, and mathematics teachers' evaluation) while controlling the covariate, socioeconomic status. The results indicated that there were no benefits in same-gender single-parent households. Furthermore, daughters in single-father homes performed better than other parent and child combinations on academic achievement. Implications of these findings are discussed. (Contains 1 table.)
