Higher education students, formally adults, are nevertheless subject to adultism. The co-authors of this article--the director of the Students as Teachers and Learners (SaLT) program and three undergraduates who have worked in pedagogical partnership with faculty through SaLT--discuss how this program counters adultism on three levels: conceptually, structurally, and personally/interpersonally. We conclude with implications of this work for others interested in creating structures, practices, and relationships that counter adultism in higher education.
