The comfortable learning atmosphere and small class sizes have helped Nobles excel in the classroom and become a positive force throughout the school.
That included a trip to Hawaii last year with the Young Marines. From Dec. 4-9, Nobles and his classmates traveled with First Sgt. Vivian Price-Butler to Oahu for the 70th anniversary of the Pearl Harbor attacks that brought the U.S. into World War II.
"When I went to Hawaii, I really wasn't thinking about the Naval Academy," said Nobles, who plans to major in engineering and eventually wants to be a Marine officer. "But the trip greatly raised my desire."
A primary mission of the 185-student high school, which opened in 1999, is to help students set and reach goals. The school looks at students' academic and social abilities and makes sure they are as independent as possible when they leave school.
Beth Sahhar, Nobles' educational case manager and a teacher at Kennedy Krieger, feels that he has set realistic goals.
"We knew Bob was exceptional from day one," Sahhar said. "He's the first person to offer assistance to others, and he's actually able to teach some of the concepts to his classmates. He's a special kid."
While Nobles is not shy about showing his leadership skills, he is satisfied to let others share the spotlight.
Asked whether he would like to return as a school ambassador in his senior year, Nobles said, "why take all the glory when you can share it amongst your peers?"
"That's very indicative of Bob's mentality," Sahhar said. "He is extremely gracious and humble. He's very personable and friendly, and he can also be really funny. Bob is just a great role model for all of the kids here."
