Jo Duncan became a headmistress at 34 with no senior leadership experience because someone saw something in her she hadn't seen herself. Now leading Wycombe Abbey, one of the UK's top girls' boarding schools, Jo shares what makes their mixed-age dormitories unique, why she's sceptical of boys' schools taking girls in sixth form and what a delayed flight from Delhi taught her about leadership. Plus: her thoughts on "sharenting", the smartphone debate and where the independent sector goes from here.
