She was baptized in the Chapel Royal at St. James's Palace on 20 December 1988, her godparents being:
- Viscount Linley (her father's cousin)
- The Duchess of Roxburghe (now Lady Jane Dawnay)
- The Hon Mrs John Greenall

She was named after The Princess Beatrice (youngest daughter of Queen Victoria), after Queen Mary (The Queen's grandmother) and after the Duchess' mother's second name.
She began attending school in 1991, at the Upton House School. She then moved onto Coworth Park School, before attending St. George's School. She was diagnosed with dyslexia as a youngster, so she delyayed her GCSE Exams a year as a result. She remained at St. Georges for her A-Levels, where she gained grades: A in drama, and B grades in history and film studies. Upon completing her A-Levels, she undertook a gap year, where she spent time in Argentina, Brazil, Spain, Belgium, Switzerland, the US, and St Barts in the Caribbean. In September 2008, Beatrice began studying History at Goldsmiths, University of London., and graduated in 2011 with a 2:1 degree (BA) in History and History of Ideas.
In 2006, to mark her 18th birthday, she gave an interview, in which she stated that she wanted to use her position to assist others through charity work; she had already undertaken charitable duties alongside her mother through the various organisations the Duchess supported. In 2002, Beatrice visited HIV-infected children in Russia, and, in Britain, she supported Springboard for Children and The Teenage Cancer Trust. During the summer of 2008, Beatrice volunteered as a sales clerk at Selfridges. In April 2010, running to raise money for Children in Crisis, she became the first member of the Royal Family to complete the London Marathon.
Over the years, she has taken part of numerous official funtions. She has attended the annual Trooping of Colour and annual Christmas services since childhood. Along with her sister, she represented her father at the 2007 Concert For Diana and Thanksgiving Service. She has attended all of her cousins recent weddings-Peter Phillips to Autumn Kelly in 2008, Prince William to Catherine Middleton and Zara Phillips to Mike Tindall in 2011. In May 2011, the hat she wore to her cousin Prince William's wedding in April was offered for sale on the internet auction site eBay with the proceeds going to charity; it was sold for £81,000 ($123,325), with the money split between Unicef and Children in Crisis. Her highest profile Royal Duty to date has been when she attended the Maundy Thursday services atYork Minster with her grandparents where she mingled among parishioners, received flowers from the public, and assisted the Queen as she passed out the official Maundy money to the pensioners. Her next highest profile duty to date was when she received (along with the Earl and Countess of Harewood) the Olympic flame on the steps of Harewood House near Leeds.
