We use comprehensive data on student teaching placements from 14 teacher education programs (TEPs) in Washington State to explore the sorting of teacher candidates to the teachers who supervise their student teaching ("cooperating teachers") and the schools in which student teaching occurs. We find that, all else equal, teachers with more experience, higher degree levels, and higher value added in math are more likely to serve as cooperating teachers, as are schools with lower levels of historical teacher turnover but with more open positions the following year. We also find that teacher candidates are more likely to be placed with cooperating teachers of the same gender and race/ethnicity, and are more likely to work with cooperating teachers and in schools with administrators who graduated from the candidate's TEP.
