Shares the results of a multi-year Department of Education Arts in Education Model Development and Dissemination (AEMDD) project, in which a partnership was developed between Arts Corps and the Highline School District south of Seattle, Washington. The project examined the impact that partnerships between classroom teachers and teaching artists have on 5th and 6th grade students’ academic mindsets and behaviors, school climate, and their transition to middle school. Findings show that the students in the four treatment schools exhibited higher levels of learner behaviors, strengthened their academic mindsets and increased their ELA and math test scores when compared to students at the four control schools.
