100 female college students attending a small Catholic college in the Northeast were surveyed in order to find the relationship between attending single-sex high school and the females’ level of self esteem, motivation in the academic and career life, and gender role beliefs. Of the 100 female college students surveyed sixty attended coeducational high schools and forty attended single-sex schools. The survey questions were organized in a way which would ultimately help decide whether attending single-sex high school was more beneficial for high school girls than attending coeducational schools. The findings revealed that girls who attended single-sex high school have less traditional views about gender roles, a more positive self-concept, and put a greater emphasis on academic/career success than girls who attended coeducational high schools. These findings were not extremely significant and can only be applied to the sample population. Future research regarding the topic is necessary.
