School turnaround--a reform strategy that strives for quick and dramatic transformation of low-performing schools--has gained prominence in recent years. This study uses interviews and focus groups conducted with 86 teachers in 13 schools during the early stages of school turnaround in a large urban district to examine teachers' perceptions of the social and organizational conditions within their schools. The study shows that some turnaround schools provided more positive working conditions than others, particularly with respect to organizational function and culture. It further finds a strong association between teachers' perceptions of school-level working conditions and support for school turnaround.
