Britain’s royal family touts the Duke of Edinburgh’s Award in U.S. PHILADELPHIA — His Royal Highness Prince Edward, Earl of Wessex, is apparently a “really cool dude.” That’s according to Maya Bridges, a 15-year-old who last week met the British prince

youngest child of Queen Elizabeth II, meaning he was once third in the line of succession to the throne, behind his two brothers, Princes Charles and Andrew. But Edward got leapfrogged because his brothers had children and his nephew, Prince William, had children, too. Now, he’s 10th in line.

And so Edward, 54, has become the face of the Duke of Edinburgh’s Award, a prestigious program started in 1956 by his father, Prince Philip, the 97-year-old husband of the queen. The awards are given to young people ages 14 to 24 who dedicate six months or more to developing skills and giving back to their communities, and it’s since become the United Kingdom’s version of becoming an Eagle Scout, though it’s open to boys and girls.

Over its 60-year history, the international awards have drawn relatively little attention in the United States — about 700 young people nationwide take part now — but the program is beefing up its presence here with the lofty goal of one day enrolling 1 percent of boys and girls in the age bracket. That’s more than 400,000 young adults, according to Buffy Higgins-Beard, the CEO of the program’s outpost in the U.S.

So it’s partnering with groups like Philadelphia’s Outward Bound School, a nonprofit outdoor adventure program that every year serves about 5,000 kids and teens representing a range of socio-economic backgrounds. So far, about 15 Outward Bound participants have committed to choosing skills they want to develop in pursuit of the DOE Award.

The partnership is how kids like Maya were invited to take part in the DOE Award. A sophomore at Central High School, she has gone on two outdoor excursions with Outward Bound and now hopes to study environmental science. To earn her medal, she’ll work at least an hour per week for six months on a handful of goals, including improving publicspeaking skills.

Outward Bound’s connection is also how Ushriya Davis, 17, got involved with the DOE Award and became one of a handful of young people who met the prince on Wednesday at the Racquet Club of Philadelphia for a lesson in court tennis, a rarefied sport also known as “real tennis” that he mastered as part of his own Duke of Edinburgh Award process.

Prince Edward’s Philadelphia stop was part of a 12-day East Coast tour to play court tennis — which was played by King Henry VIII and can best be described as a mix of tennis, volleyball and chess — while also courting donations to support young people who want to get involved in the award program.

“He was funny and very humble,” she said after her court tennis lesson. “Honestly, though, I had no idea who he was until he was talking to us. Then in the moment, I was like, ‘Oh my goodness.’”

Nonetheless, a prince wearing all white and playing an odd form of tennis in one of the city’s most exclusive sports clubs doesn’t exactly scream accessibility. Outward Bound’s local interim executive director, Dan Hoffman, said he understands that to some Americans, the idea of British royalty can feel “standoffish.”

Prince Edward’s handlers wouldn’t make him available for an interview.

But Mr. Hoffman said that’s not what the award program is about. In fact, some participants weren’t even aware there was a British connection.

“Once we explain this is a pretty incredible network and looks amazing on your college resume, it makes sense,” Mr. Hoffman said. “Even I laugh when I say ‘his royal highness.’ I can’t not giggle.”
