Princess Charlotte will soon attend the "kind and gentle" Willcocks Nursery School, which sits barely half a mile from Kensington Palace.
A spokeswoman for Kensington Palace opened up about the couple's choice, saying: "They felt it was ideal as a first step for Princess Charlotte's early education and they were impressed by the team that work there."
A spokesperson for the school added: "We are delighted that The Duke and Duchess of Cambridge have chosen the Willcocks Nursery School for Princess Charlotte. We look forward to welcoming Charlotte to our nursery in January."
The two-year-old will be enrolled in the morning school, lunchtime club and afternoon school, attending from 9am until 4pm. She will be required to take in her own packed lunch and will join a range of activities including cooking, music and acting.
The "traditional" school describes the educational environment as "fun and structured" with lots of "free play where children embark on the first stages of learning to read, write and to understand simple numbers with the minimum of pressure."
It's expected to set the beloved family back an eye-watering sum of £19,770 (A$34,481) for three terms.
The choice will likely come as a surprise to royal watchers, who speculated the royal tot would follow her brother Prince George, four, to Thomas's Battersea, where he started in September.
What's more, the prestigious school is significant departure from the way in which George was first introduced to his schooling years - attending a modestly-priced Montessori nursery school in Norfolk.

The announcement accompanied an adorable new family portrait (see above), released just in time for Christmas.
The shot, taken by royal pro Chris Jackson from Getty, shows the foursome impeccably coordinated in blue hues and beaming grins.
"The Duke and Duchess of Cambridge are pleased to share a new photograph of their family. The image features on Their Royal Highnesses' Christmas card this year. The photograph shows The Duke and Duchess of Cambridge with their two children at Kensington Palace. It was taken earlier this year by ChrisJacksonGetty," the caption reads.
While Kate and William are obviously well versed in smiling for photos, and George and Charlotte are sporting the kind of almost-grins that could melt even the coldest of hearts.

But that wasn't the only new picture the palace shared today. Charles and Camilla's 2017 Christmas cards were also revealed via the official Royal Family Instagram.
"Here is this year's official @clarencehouse Christmas card from The Prince of Wales and The Duchess of Cornwall," the caption simply states.
"The photograph was taken by @hugoburnand at Highgrove in July during the private 70th Birthday party of The Duchess of Cornwall."
Christmas has well and truly come early this year!
