The Sequential Intercept Model (SIM)

The SIM details how individuals with mental and substance use disorders come into contact with and move through the criminal justice system. The model helps communities identify resources and gaps in services at each intercept and develop local strategic action plans. The SIM mapping process brings together leaders and different agencies and systems to work together to identify strategies to divert people with mental and substance use disorders away from the justice system into treatment.
