The sub-series provides insight into the Black Theatre Workshop’s (BTW) many initiatives to support young performing artists. A first attempt to install a program to support young artists was the Beginners’ Workshop, which took place in January and February 1984, followed by an 11-week project known as the Summer Theatre, which took place during summer of the same year. The idea was revived with the installation of the Youthworks Program, which existed from 2002 to 2013. This workshop series offered free specialized theatre training for Montreal teenagers from 12 to 25 years old, who envisioned a career in the performing arts. Each spring the workshop series finished with the presentation of a play, as there were, among others, Shakin' the Mess Outta Misery ; Death of the Bourgeois Dream ; What If?, and Urban Legends / The Procrastin8r.

The sub-series contains play scripts, brochures, meeting notes, reports, program outlines, communications, photographs, schedules, photographs, and sound recordings, among other documents.
