This quantitative study used descriptive statistics to evaluate data obtained from 179 middle grade teachers, grades 5-9, currently working in a single-gender environment, including public, private, and charter schools, with regard to the academic and behavioral benefits of single-gender education. The study used a survey created by Dr. John Fry in 2009 for his doctoral dissertation, "Single-Gender Education: Teachers' Perspective," and sought to confirm or refute his conclusions regarding the efficacy of single-gender education as recommended in his section for future research. The results of this study confirm his conclusions and indicate the teachers have positive perceptions regarding single-gender education, particularly in relation to academic achievement and behavioral change.
