Prince William and Kate Middleton have decided to have Princess Charlotte be educated at a different school from Prince George once they reach high school age, according to insiders.

Charlotte is said to be following in her mother’s footsteps by eyeing up Marlborough College in Wiltshire, England, the Daily Mail reports.

The Princess of Wales, 43, studied at the school before meeting William at St. Andrews University years later.

Marlborough College, also attended by Princess Eugenie and Pippa Middleton, was always a strong frontrunner for both children, as well as Prince Louis, 7.

For his part, the future king, 11, is set to enroll at the prestigious Eton College — William and his estranged brother Prince Harry’s former school, which has long been a popular choice among royals, politicians and aristocrats.

Prince George, Princess Charlotte and Prince Louis are all currently enrolled at Lambrook School in Berkshire, England, which sits nearby their Adelaide Cottage home.

Once George turns 12 in July, however, he will be moving to the $82,000-per-year college in September.

According to sources, the decision to send George to Eton has already been finalized and the school’s staffers have displayed a certain “smugness” about the impending announcement.

“I know something and the people at Eton know something, but I’m not going to tell you,” an insider told the outlet. “That was after William and Kate visited Eton.”

The outlet previously reported that George was registered to enroll at Eton “several years ago,” with one insider saying, “All roads lead to Eton.”

The Post has reached out to Kensington Palace for comment.

William, the heir to the throne, had a great experience at the school, but Harry, 40, detailed a completely different experience in his bombshell 2023 memoir, “Spare.”

The former working royal, who now lives in Montecito, Calif., with his wife, Meghan Markle, and their two children, admitted he struggled with poor grades when he attended.

His disappointing academic experience prompted him to skip university and head straight to the Royal Military Academy Sandhurst.

The Duke of Sussex wrote that Eton was “heaven for brilliant boys, it could thus only be purgatory for one very unbrilliant boy.”

Eton College is located a short stroll away from William, 42, and Kate’s family home at Adelaide Cottage in Windsor Home Park.

Prior to committing to Eton, the young royal had toured two other schools in North London, including Highgate School.

Despite the report, Kensington Palace has yet to formally announce the future of George, Charlotte and Louis’ education.
