Prince George will not be starting secondary school in September, despite turning 11 this summer.
He presently attends Lambrook School in Berkshire, alongside his siblings Princess Charlotte, nine, and Prince Louis, six. Unlike many public schools, Lambrook accepts pupils up to the age of 13, or Year 8.
Seward stated, "They will have their choice of colleges, and they may look at as many as they want, and they do not have to make a decision nearly as soon as anybody else would. So they have the advantage."
The three most active royal dynasties attended a variety of prestigious institutions, including Eton College in Windsor, Marlborough College in Wiltshire, and Gordonstoun in Moray, Scotland.
According to Seward, the Prince and Princess of Wales have "looked at Eton".
However, the editor of Majesty Magazine said that Kate "probably doesn't want him to go to boarding school at all, and it's possible that he won't".
She then on, "But that's what makes Eton appear quite plausible, since it's so close to where they live.
"Prince Louis and Princess Charlotte will still be at their current school, and when and if George gets into Eton, which of course he will, he will just be down the road from them."
William and Kate have also been spotted visiting the latter's former haunt Marlborough twice in the last two months, and rumors have circulated about St Edward's School in Oxford.
Though Seward claimed "the world is their oyster" when it comes to picking a school, adding that no institution in the country would dare to turn down the royals.
However, in order to get admission to any conceivable private educational institution, George will be required to sit for selective entrance tests.
