During the past several years, there have been growing concerns regarding the effectiveness of school discipline policies, as well as their disproportionate impact on African American and Latino students. For at least a decade, questions have been raised about district-level "zero tolerance" policies that have contributed to larger numbers of students being suspended or expelled for non-violent offences. Attempts to reform school discipline policies in California have gained momentum in recent months, most prominently in a series of bills that have been approved by the state Legislature and are currently awaiting Governor Jerry Brown's signature. Yet little is known about how school discipline policies are actually being implemented in individual districts across the state. To find out, EdSource conducted a survey in the spring of 2012 of administrators in charge of school discipline policies of all California districts with a student enrollment of more than 1,000 students. It is the first such survey to be conducted of California school districts. Responses were received from 315 school districts--a 56 percent response rate. These districts, with enrollments totaling 4.1 million, educate two-thirds of all students in California schools. This report sheds light on a wide range of issues related to school discipline, including school administrators' views on the adequacy of state laws and regulations, the costs of imposing school discipline policies, the extent to which districts are relying on alternative approaches to school discipline, the use of data to improve student discipline outcomes, and the average length of suspensions.
