I am considering a 3 year project near Liverpool and would be coming with my wife and 14 year old daughter. My biggest issue is schools for my daughter. Since this would be a temporary assignment, I would like her to maintain a somewhat American curriculum. My family are experienced expats and have lived in Ireland, Singapore and Poland in the past. Any advice or assistance in finding information, particularly about schools for my 14 year old would be most appreciated.
