As states are continuing to refine teacher evaluation models, there are opportunities for student learning in the arts to be documented and connected with teacher evaluation. The Tennessee Portfolio of Student Growth in the Arts ("the Portfolio") has provided a new perspective on documenting the relationship between student growth and teacher evaluation in the fine arts. It also offers a reliable and rigorous process for art educators to generate an individual growth score and engage in data-driven reflective teaching practice. The Portfolio allows fine arts educators to document and reflect on the work that students do in a way that previously did not exist. This documentation generates an individual growth score that replaces the previous schoolwide growth measure. The Portfolio uses a purposeful collection of authentic student work artifacts that are grouped into four collections representative of the course load of the educator, based on the state's academic standards, and differentiated based on student proficiency. This White Paper provides a snapshot of a portfolio assessment model and serves as a model for other states and regions to integrate what has been learned from the Tennessee Portfolio of Student Growth in the Arts. Assessment White Papers for Art Education is a collection of essays that teach about current and established assessment practices and theories, and how they are relevant to all of the National Art Education Association's membership. This series offers a starting point for NAEA members--across all levels--as well as parents, administrators, and the general public to understand assessments' applications to art education.
