Typically, children in the royal family were educated by a governess in the palace, but Diana made sure that Prince William would be the first heir to the British throne to be enrolled in public school as soon as he was of age. At 3 years old, William began attending nursery school, and when his own son George was just 2 1/2, he and wife Kate had him start at the Westacre Montessori School. William and Kate's 5-year-old daughter Charlotte and 6-year-old son George both attend Thomas's Battersea School, a private school in South London.
