Northeastern University and Boston Ballet are partners in a novel initiative that allows dancers to earn a college degree while they dance, a challenge for dancers who practice and perform for up to 12 hours a day.

Boston Ballet is not the only professional ballet company to collaborate with a university, but it is the only one that allows dancers to choose from an array of degrees.

Classes will be conducted online, on campus, or at the Ballet’s Clarendon Street headquarters, such as this one was.

Dancer Brittany Stone is one of those taking advantage of the on-site classes. She observed a sociology class recently being taught at the dance company.
