During her initial run, JoJo was consistently listed as a 9- to 10-year-old dancer in press materials and episode credits. The Abby Lee Dance Company was led by choreographer Abby Lee Miller, who managed the team's competition schedule across multiple states. Dance Moms episodes typically followed rehearsal, costume fittings, and live competition footage, with on-screen graphics often confirming the dancers' ages each season. The show's format relied on weekly scoring, parental interviews, and solo routines that highlighted individual dancer profiles. Lifetime
