JMU is not rolling, but if you apply academically EA, and audition in the fall at JMU you may find out when you receive your academic acceptance in January whether or not you have also been admitted to the major. We do keep many fall audition, January admit students on Hold until we have completed all auditions, but all EA academic admits hear by late February/very early March if they have also been admitted to the program.
RD applicants find out academic and artistic admission at the same time in late March.
