Arts organizations that partner with schools to design, implement, and evaluate arts education programs are rethinking traditional practices of evaluation to more directly engage school partners, artists, and administrators. External arts partners are also being held accountable for learning outcomes that result from their programs. In this article, the authors describe an urban arts organization that is moving toward an institutional culture that engages teachers, artists, students, parents, and administrators in a process of documentation and action research that enhances the ability to evaluate teaching and learning. This layered research approach within an arts organization enables participants to link teaching standards to student work and contributes to the larger dialogue about arts education programs in schools.
