This document provides a formative and outcome evaluation report of the El Sistema Mitchell Music Program pilot conducted from October 2013 to April 2014. The program was a partnership between the University of Michigan schools of Music, Social Work, and Education with Ann Arbor Public Schools to provide string instrument instruction to 22 fifth-grade students at Mitchell Elementary. Data collected through surveys, interviews, videos, and academic records found that students significantly improved in feelings of acceptance and school engagement. Students also exceeded academic growth benchmarks in reading and math. Challenges included attendance, balancing individual/group instruction, and expanding opportunities to all students. The program provided benefits to both students and University instructors.
