A few years later, Cuyjet began sending Jamison to other teachers to advance her dance education. She learned the Cechetti method from Antony Tudor, founder of the Philadelphia Ballet Guild, and studied with Delores Brown Abelson, a graduate of Judimar who pursued a performance career in New York City before returning to Philadelphia to teach. Throughout high school, Jamison was also member of numerous sports organizations, the Glee Club, and the Philadelphia String Ensemble. She studied Dalcroze Eurhythmics, a system that teaches rhythm through movement.
