Learning in and through the arts develops the essential knowledge, skills, and creative capacities all students need to succeed in school, work, and life. As the top building-level leaders, school principals play a key role in ensuring every student receives a high-quality arts education as part of a complete education. In a time of shrinking budgets and shifting priorities, what can school principals do to make and keep the arts strong in their schools? This guide offers three concrete actions school principals can take to increase arts education in their schools: (A) establish a school-wide commitment to arts learning; (B) create an arts-rich learning environment; and (C) rethink the use of time and resources. Each action is supported with several low-cost or no-cost strategies that other school leaders have used and found to be effective--whether it's beginning an arts program where none exists, making an existing program stronger, or preserving an arts program against future cuts. School principals and other leaders interested in increasing arts education in America's schools can adopt any of these actions and strategies one at a time or implement several at once. When taken together as part of an overall approach, however, their effects are more likely to be cumulative, mutually reinforcing, and more sustainable over time. (Contains 1 footnote.)
