We are relocating to London from Chicago in January 2012, so I am very new to the organization of the school system in the UK. My daughter is 11-years-old and starting 6th grade here in the United States. Would it be better for her to attend a primary school that goes up to 13-years-old (she could then attend the same school as her 8-year-old brother), or should I place her in an independent secondary school apart from her brother? We expect to be in the UK only 2-3 years, and then return to the US for high school. (I am not very interested in sending my children to ASL.)
