Sure Prince George and Princess Charlotte are born into royalty and enjoy several perks that elite kids have. But as they enter school, their stature comes with a price.

The little princess just started her formal education at Thomas’s Battersea school, the same institution where her big brother currently attends, and the place seems to have a rather unique policy. Journalist Jane Moore explained that best friends are not encouraged because it is expected of the students to “be kind” to all of their classmates.

“There’s a policy that if your child is having a party, unless every child in the class is invited you don’t give out the invites in class, which I think is quite a good thing as you don’t feel excluded,” Moore expounded. “There are signs everywhere saying be kind, that’s the ethos of the school,” she revealed.

Both Kate Middleton and Prince William took the time to drop off both kids at school, at which her dad noticed that little Charlotte was “very excited.” George started attending Thomas’s Battersea two years ago when Kate missed his first day due to morning sickness while pregnant with Prince Louis.

The London public school’s curriculum also boasts some pretty fancy subjects. According to their website, year 1 and 2 students cover these subjects: Literacy, Numeracy, Science, History and Geography, RS, French, PSHCE (Personal, Social, Health and Economic Education), Art, Computing, Music, Swimming, Ballet, PE and Games.

“A stimulating environment, including a multisensory outdoor play area, supports the teachers’ planned activities and the children’s own initiatives for learning,” the website explained. It’s easy to see why the school was chosen for the princess.

Additionally, George has been reported to be “doing very well” at school. He is being treated like other five-year-olds, so much so that either Kate or William can drop him off without any fuss.

Before she entered Thomas’s Battersea, the 4-year-old Charlotte had attended Willcocks Nursery since January. She will be donning her surname, “Cambridge,” which is based on her parents’ house. She is registered as Charlotte Cambridge, while George is known as George Cambridge.
