The Case Against Single-Gender Classrooms. In 2007, Jefferson Leadership Academies reversed its same-sex curriculum after issues with disappointing test scores and scheduling conflicts arose. Detractors of same-sex classrooms weren’t surprised since one of the biggest challenges to single-sex classrooms is the lack of concrete evidence that they boost achievement. There are plenty of schools to choose from too: More than 500 institutions are counted as members of the National Coalition of Girls Schools and the International Boys’ Schools Coalition. And private schools are not the only avenues for single-sex learning environments, as there are about 850 entirely single-sex public schools.
Although single-sex education was once the norm in the U.S., the practice has largely been confined to private schools for more than a century. However, with the introduction of the final version of the U.S. Department of Education's so-called single-sex regulations in 2006, public schools were allowed greater flexibility to offer single-sex opportunities.Cited by: 17.
