Recidivism is calculated as a percentage of all alleged perpetrators in abuse/neglect investigations closed without services who were a confirmed perpetrator within 12 months after the prior investigation was closed without services.

Calculating this way, for example, the Fiscal Year 2019 rate reflects recidivism of alleged perpetrators in investigations closed without services in Fiscal Year 2018, the Fiscal Year 2018 rate reflects recidivism among alleged perpetrators in investigations closed without services in 2017, and so on.
