Willcocks Nursery School, founded in 1964, offers activities for children between ages two and five including poetry, acting, snack time, singing and show and tell.
The duchess' love of repeating outfits makes her one of the more relatable members of the Royal Family, and fans on Twitter have constantly given her praise for it. This is because her nanny Maria Teresa Turrion is a Spanish native, and must sometimes speak to the tiny Princess in her native language.
The young princess is said to have learned Spanish phrases from her Spanish nanny, María Teresa Turríon Borallo.
Princess Charlotte was all smiles before heading off to her first day of preschool. It charges just over 3,000 pounds a term ($4,000) for those who attend mornings Monday to Friday.
"It's right to talk about motherhood as a wonderful thing, but we also need to talk about its stresses and strains", she said at a maternity mental health event past year.
It has also been revealed why Charlotte won't attend the same nursery as her older brother did.
"She's very sweet and very confident - she's always chatting away."
Just two years old, Princess Charlotte was described as a natural tennis player by reports that emerged last month, but it seems that's not all. Online: "She will be spending the day privately".
