My ds and my niece are both starting secondary school in September and are both going to single sex schools. This is just a coincidence and we both picked the schools for other reasons but I was just wondering IS it better or not to go to a single sex school. A Headmaster at another school we looked round that was also all boys said Yes, boys work in a totally different way to girls and therefore being a all boys school was an advantge, but then he would wouldn't he? What do you think?
