This study compared the experiences of women attending women's colleges with those of women attending coeducational institutions. Analyses of data from the National Survey of Student Engagement (NSSE) from random samples of female first-year and senior students from 26 women's colleges and 264 other four-year institutions were conducted. Women at single-sex institutions were more engaged in effective educational practices and reported higher levels of feelings of support and greater gains in college. With regard to the effect of different backgrounds on college experiences, transfer students at women's colleges were as engaged or more engaged than students who start at and graduate from the same school, and students of color tended to be less engaged than White students.
