How could the shift away from death row affect the COMPAS risk assessment model?
The COMPAS model's predictive validity may be challenged by California's operational changes. Governor Gavin Newsom's policies have driven significant operational changes within the California correctional system, including the suspension of the death penalty in 2019 and the subsequent dismantling of the condemned housing unit at San Quentin. These changes have led to death row residents being gradually transferred to general population facilities, such as a section of California State Prison-Sacramento. This fundamental shift alters the population profile and the range of risk factors used by the California Department of Corrections and Rehabilitation. Consequently, the predictive accuracy of tools like COMPAS, which relies on specific risk variables tied to the severity of incarceration, could be affected.

How it reaches COMPAS
-
Wesley Shermantine died in prison on September 17, 2026, at California State Prison in Sacramento, while on death row. Governor Gavin Newsom placed a moratorium on executions in 2019. Separately, Governor Gavin Newsom directed officials to block Tina Peters' parole transfer to Shasta County, criticizing her hiring as a felon convicted of tampering with voting machines.
The full event3independent outlets -
The California Department of Corrections and Rehabilitation is responsible for managing these operational changes, moving inmates from severely isolated death row settings to general population. This shift fundamentally changes the demographic and risk profile of the population being assessed by risk prediction tools.

Why it matters
COMPAS is a critical tool used by the California Department of Corrections and Rehabilitation for functions like recidivism prediction and post-release behavior analysis. The tool's effectiveness relies on consistent data inputs and a stable understanding of the risk factors associated with different levels of incarceration. Any major shift in the population being assessed or the severity of the potential outcomes directly impacts the reliability of the model.
This change reflects a broader philosophical shift in California's approach to incarceration, moving away from harsh punitive conditions and extreme isolation toward environments that allow for general population status and self-improvement. The success of this new approach, and the integrity of the tools used to manage it, are key questions for the state's criminal justice system.
What we don't know yet
- How will the CDCR adjust its risk assessment protocols to account for the shift from death row to general population?
- Will the new operational protocols require recalibration or replacement of the COMPAS model?
