Children increasingly interact with police on school grounds. Most research on police in schools focuses on school safety. However, police also question children at school as witnesses, suspects, and victims during a criminal investigation. The current study explores police policies about interviewing and interrogating children at school. We explored how many of the police departments of the largest 100 U.S. cities had policies related to questioning children at school and analyzed the content of these policies. We found that 40% of police departments had a policy of school-based questioning. These policies rarely covered issues related to students' legal rights and largely focused on adult-related issues like notification of the child's parent and permission of school officials.
