The single-sex school originated during the 18th century, when rich families sent their sons to “special” schools. Only later, in the 19th century, when the awareness of the value of education increased, were girls also sent to study. Single-sex schools were very popular in England and now also in Australia.
Today, the single-sex schools are popular among religious populations and even more during high school.
Supporters of single-sex schools believe they help kids concentrate on their academic work and avoid the sexual distractions of adolescence.
Critics believe that some social skills relating to the opposite sex reaches its peak development during teenage and that if teens do not have enough practice, this limit their social skills and their ability to relate later on.
