The Duchess of Cambridge is due to resume solo royal duties for the first time since her second child, Princess Charlotte, was born in May.
She will see how the Anna Freud Centre in central London treats children and young people with mental health issues.
It is Kate’s first official engagement since the birth and reflects her interest in the charity’s area of work.
The duchess was seen in public at a number of events this summer including Trooping the Colour and Wimbledon.
And Princess Charlotte was christened at a church in Sandringham in July.
The duchess’s visit to the Anna Freud Centre will take her to the site of the charity’s family school, and its planned community campus, both located near King’s Cross.
The centre, which began life in 1941, is named after Anna Freud, a pioneer of child psychoanalysis and daughter of psychoanalyst Sigmund Freud.
The charity’s planned community campus will see experts in mental health, neuroscience and education work with children and families to develop new treatments and approaches.
The family school, which opened on a temporary site in September last year, provides alternative education for children who are at risk of exclusion and are struggling to achieve.
