In 1963, at the urging of her mentor, George Balanchine and Barbara Weisberger established the School of Pennsylvania Ballet.  In 1986, Bo Spassoff became Director of the school. After six years of steady growth, The Rock School became an independent, not-for-profit institution focusing intensely on its mission: excellence in dance education. Over the past 30 years, Bo, along with Co-Director Stephanie Wolf Spassoff and the Trustees of The School, have transformed a small regional school into an internationally acclaimed institution.

Throughout it's over 50-year history, the school has developed dancers for most premier dance companies throughout the world. Our faculty includes distinguished dancers, instructors, and choreographers. Additionally, The Rock School owns the best ballet training facilities in the Philadelphia area, with Rock Center in the city and the West Chester branch school, Rock School West, in the suburbs. To compliment The Rock School’s ballet training, Rock Academics provides flexible but rigorous 7-12 grade course work while Residence provides a nurturing and convenient home away from home for elite national and international ballet talent. All told, annual enrollment exceeds 1,200 students, with a budget in excess of $5.8 million. Because the Professional Division students are the dance stars of tomorrow, The Rock School awards more than $900,000 in annual scholarships to its dancers.

Our dancers are consistently awarded the highest ranks at Youth America Grand Prix, the largest ballet competition in the world. For an unprecedented thirteen consecutive years, The Rock School has been awarded “Outstanding School” by Youth America Grand Prix and was the only school asked to perform at the YAGP 15th Anniversary Gala in Lincoln Center, New York City in 2014. Rock students have competed and received honors in the Prix de Lausanne, World Ballet Competitions, USA International Ballet Competition, Moscow IBC, & Berlin Tanzolymp.
