The Duchess of Cambridge will visit her old preparatory school today.
Kate will have a trip down memory lane when she returns to St Andrew's School in Pangbourne, Berkshire.
The Duchess attended the private school, where fees are now £4,760 per term, for Years five to right - from 1986 until 1995.
Kate will join pupils for St Andrew's Day, which the school traditionally marks with a day of activities.
The institution takes both boys and girls aged from three to 13 and pupils can also board.
The Duchess, now a future queen, was predominantly a day girl at St Andrew's but in her later years also boarded for part of the week.
A spokesman for the Duchess said: "She was invited to go back and was very keen to do so. It's the first time in many years she has been there."
Kate will meet teachers and students at a private lunch, visit the pre-prep school for under-fives and formally open a new Astroturf playing field.
The Duchess, who played hockey at St Andrew's, will meet the hockey team, tour the school and see pupils competing in the Progressive Games - traditional indoor games marking St Andrew's Day.
She joined the school when her family returned to West Berkshire in 1986 after spending two-and-a-half years in Jordan.
