The Marble Collection (TMC) is a nonprofit organization that cultivates creativity and excellence in the arts by engaging teen artists and writers in a publication process that affirms their voices and deepens their learning. To fulfill our mission, TMC publishes the Massachusetts High School Magazine of the Arts—the only statewide, juried print and online magazine that features artwork, photography, poetry, and creative writing by teens in grades 8-12. We also offer Massachusetts teen artists and writers our Mentoring for Publication Workshops. The 6-week workshops are free for teens and available both online or in-person. Teens are paired one-to-one with college student mentors who provide editorial feedback to help them refine their voices and revise their work for publication.
