No doubt bringing back memories from her own schooldays, the Duchess of Cambridge was guest of honour at the Place2Be Headteacher Conference to discuss the ongoing work on the mental health of schoolchildren across the UK.
Headteachers from around the country joined her at the event, to talk about tackling mental health in the classroom and share their success stories. There were also presentations by child psychologists and young people.
Kate is a Royal Patron of Place2Be because of her personal interest in the mental health and emotional wellbeing of children. She recorded a special video message for the organisation in February this year.
Kate's appearance at the headteachers' conference came the morning after she attended The Fostering Network's Excellence Awards in London, which were hosted by Holly Willoughby.
The 33-year-old duchess presented a special awards to three youths for their work in the fostering community.
Earlier that day, she joined husband Prince William to sign a book of condolences for victims of the Paris terror attacks.
