Without the need to deal with male-female socialization problems on a daily basis, students can continue their studies, class discussions and school activities. Additionally, studies have shown that after the transition to single-sex education, many schools found that students' scores increased. At Stetson University, researchers compared test scores from a single-sex class and a coed class at Woodward Avenue Elementary School in Florida. After the fourth year of study, in January 2008, 55% of boys in coeducational classes scored advanced on the FCAT compared to 85% 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 achievement. Additionally, Heather McRae, principal of the Diocesan School for Girls, said NCEA findings show that single-sex girls' schools give New Zealand teenagers the best chance of achieving the best academic results. “In 2014, 55.9% of those who completed NCEA Level 1 at the K-10 school achieved an A-level, compared to the national average of 17.7%. Meanwhile, 34.2% of girls from all schools in the same decile achieved excellence at first level, compared to 24.1% of girls from mixed schools in the same decile.”
