In the LACHSA Theatre Department, all first-year students are required to participate in the junior varsity DTASC competition. After their first year, second- through fourth-year students have the opportunity to compete in varsity DTASC if they choose to (with approval from the department). DTASC, which stands for the Drama Teachers Association of Southern California, brings together thousands of high school students from across Southern California to compete in a wide variety of theatrical categories, including monologues, large group comedy, musicals, small group performances, and many others. Performances are evaluated by professional adjudicators through multiple rounds of competition, beginning with preliminaries and advancing to the semi-finals and finals. The event is a fun, full-day experience where students not only compete, but also make connections with like-minded performers from other schools.

During her second year at LACHSA, Belle chose to participate in the varsity musical category as a performer, playing the Emcee in an abridged production of Cabaret directed by her classmate and friend, Ava Espinosa.

For her third year of DTASC eligibility, Belle decided to try her hand at directing, entering a scene in the drama category. During her time at LACHSA, she has read many plays that have inspired her, but one script in particular stayed with her because it perfectly encapsulated the type of stories she hopes to tell through Brunette Productions. The Sweet Science of Bruising by Joy Wilkinson tells the story of an unlikely group of women who defy the odds by finding empowerment and freedom in the underground world of female boxing in 1869 London. Inspired by its themes of resilience and female empowerment, Belle cast a group of close friends and classmates to portray these powerful women and carefully crafted a version of the play that fit within the competition's eight-minute time limit. The group's performance advanced to the semi-finals in the drama category.
