Without having to deal with gender socialization issues on a daily basis, students can continue their studies, class discussions, and school activities. Additionally, studies have shown that after switching to single-sex teaching, many schools found that student achievement increased. At Stetson University, researchers compared test scores from a single-sex class and a co-ed class at Woodward Avenue Elementary School in Florida. After the fourth year of the study in January 2008, 55 percent of boys in co-ed classes scored satisfactorily on the FCAT, compared to 85 percent of boys in all-boys classes (Cable and Spradlin 5). A single-sex environment has the ability to enhance students' academic careers and maximize intellectual performance. Additionally, Heather McRae, headteacher of the Diocesan Girls' School, said the NCEA results showed single-sex girls' schools gave Kiwi teenage girls the best chance of achieving the best academic results. “In 2014, 55.9 per cent of those who completed NCEA level one in decile ten school achieved an excellent grade, compared to the national average of 17.7 per cent. Meanwhile, 34.2 percent of girls in all single-sex schools in decile ten achieved excellence at level one, compared to 24.1 percent of girls in mixed schools in the same decile.”
