Other boarding school options have been chosen by the royals including Eton, where both Prince William and Prince Harry studied.
Many royals will also attend all-boys or all-girls private schools.
However, Kate has already shown she is happy to make different decisions when it comes to her children’s education.
Rather than following what is traditional in the family, Kate and William have reportedly been more focused on what is best for their children.
Zoe Bonser, Show Director at The Baby Show, told Express.co.uk: “Kate also values quality family time and has broken some traditions.
“For example, sending George to a mixed school, dropping George off at school herself, or having her mum to help after births rather than an army of staff.”
The Duchess may be more concerned with finding a school that is the right fit for her children rather than following the lead of other royals.
In September 2017, Prince George started his education at Thomas’s School in Battersea.
Last year, Princess Charlotte also joined the same primary school.
Not only was this choice different from other where previous royals have been, it is a mixed primary school.
Speaking to Katie Nichol in Vanity Fair, a source said: “They are part of the school community, they get on well with the head and they have been thrilled with how much George has come on since he started.
“Charlotte has got a real character, she is very excited about starting school.”
