The Duke and Duchess of Cambridge have announced which school Prince George will attend in September.
The prince, who turns four in July, will go to Thomas's Battersea when the new school year begins, according to Kensington Palace.
In a statement, the Palace said: "Their Royal Highnesses are delighted to have found a school where they are confident George will have a happy and successful start to his education."
The school, just a few miles from the family's main residence at Kensington Palace in London, educates 540 boys and girls between the ages of four and 13, according to its website.
Day fees cost £6,110, according to last year's Tatler Schools Guide, which noted the school's particular success in sport and drama.
The guide added: "Entrance at 4+ is selective, with 60 places up for grabs (they close the list at 180 registrations).
"Lots of Chelsea and South Ken families here, who get very stuck into the community."
Headmaster Ben Thomas said: "We are honoured and delighted that Their Royal Highnesses The Duke and Duchess of Cambridge have chosen Thomas's Battersea for Prince George.
"We greatly look forward to welcoming him and all of our new pupils to the school in September."
Writing about the school on its website, Mr Thomas said: "Whilst we are proud of our record of senior school entrance and scholarship successes, we place a greater emphasis on a set of core values, which include kindness, courtesy, confidence, humility and learning to be givers, not takers.
"We hope that our pupils will leave this school with a strong sense of social responsibility, set on a path to become net contributors to society and to flourish as conscientious and caring citizens of the world."
The school's website said it was "receiving a very high volume of traffic" on Friday afternoon.
Prince George has been attending Westacre Montessori School nursery school near the family's home in Norfolk since January 2016.
But they plan to spend more time at Kensington Palace as the Duke of Cambridge concentrates on his royal duties.
Despite his young age, the third in line to the throne has already toured places such as Australia and New Zealand and met world leaders including Canada's prime minister Justin Trudeau and former US president Barack Obama.
The choice of schools is a departure from Wetherby School in Notting Hill, where both George's father William and uncle Prince Harry attended as youngsters.
Prince George's younger sister Princess Charlotte, two, is expected to start nursery school in May.
