Professional development can help to ensure teaching artists have the requisite knowledge and skills to lead effective instruction. However, the specific format of professional development can vary. One organization that provides professional development for their teaching artists is the Youth Orchestra Los Angeles (YOLA) program, which is an El Sistema-inspired program. In many communities there is a lack of access to a quality music education, and El Sistema-inspired programs attempt to provide opportunities for access to musical experiences through private lessons and large ensemble settings. Grecia Serrano Navarro provides a unique perspective concerning El Sistema-inspired programs, as well as the backgrounds, preparation, and professional development of teaching artists. Her story outlines her experiences of pursuing classical music study in high school, earning a degree in music education, her public school teaching experience, and her current role as a provider of professional development for teaching artists at YOLA. Through examining Grecia's experiences, along with related literature providing contextual support for her perspective, the role of El Sistema-inspired programs is considered, including the structures of support that these programs provide aspiring musicians. The varied paths of preparation and professional development for teaching artists who work for El Sistema-inspired programs are also examined, including the impact of music teacher education on the field of teaching artistry.
