SB 36: What Does Tool Validation Involve?
June 10, 2025
California Senate Bill 36 requires agencies conducting pretrial risk assessments to complete a validation at least once every three years.
Local validation studies are not just a requirement of SB 36 but an opportunity for your agency to improve your pretrial practices while ensuring equitable, safe, and timely release of eligible defendants.
The validation process is multi-pronged and unique for every agency. In short, effective validation involves a combination of technical statistical analysis and collaborative problem solving. Specific areas of expertise are needed to approach the complex requirements of SB 36:
- Strategizing: Creating a custom plan to address your agency’s unique needs and resources
- Qualitative learning: Understanding your local pretrial practices to ensure alignment with evidence-based best practices
- Rigorous analyses: Utilizing proven statistical methods to assess predictive accuracy
- Equity: Verifying that your agency’s chosen tool is working effectively for all populations
- Data security: Ensuring the confidentiality and integrity of sensitive information
- Sustainability: Building protocols and expertise within your agency
