Abstract:Given the mixed results of previous studies on the benefits of single-sex schooling, scholars have called for research on differences in the effects of single-sex schooling based on student and school characteristics. We sought to examine the associations of a range of student characteristics with attitudes and achievement among students attending an all-girls public middle school in the southwestern United States. Predictor variables included demographic factors (i.e., race, family income), prior academic achievement, gender stereotyping, and gender identity (i.e., gender typicality, peer preferences). Prior academic achievement predicted later achievement and persistence in the single-sex school. School-related stereotyping was associated with success in and connection to the single-sex school; school connection was also a significant moderator of the relation between stereotyping and academic performance. Gendertyped peer preferences were associated with school connection and persistence. Overall, results indicate that student characteristics, as well as issues of "fit" with the specific school, are associated with students' connection to and success in single-sex educational environments. .
