In recent years, arts partnerships have gained increased popularity as a means of delivering arts education and art-in-education in schools. Creating opportunities for both teachers and artists alike, arts partnerships can enhance a shared sense of purpose and mutual respect, while also developing creative skills, knowledge and expertise. Although many studies on both national and international levels have identified the successes and challenges of arts partnerships in schools, a gap in how these partnerships can enhance teachers' professional development regarding arts education still exists. Therefore, this article discusses the potential impact of arts partnerships and whether these collaborations can act as a professional development initiative, to potentially enable and support teachers in their enhancement of arts education. The evidenced impacts, possibilities and indeed, challenges of such arts partnerships in schools are explored while arts partnerships approaches, policies and directions on a both national and international level, are also discussed. Literature is also critically reviewed regarding the facilitation of, and teacher professional development in, arts education.
