Brian A. Jacob and Joseph Ryan:

This report presents findings from a unique partnership between the University of Michigan and the State that allowed us to match the universe of child maltreatment records in Michigan with educational data on all public school children in the state. We find that roughly 18 percent of third-grade students have been subject to at least one formal investigation for child maltreatment. In some schools, more than fifty percent of third graders have experienced an investigation for maltreatment. These estimates indicate that child abuse and neglect cannot simply be treated like a secondary issue, but must be a central concern of school personnel.
