Prisons and reformatories; modifying provisions related to inmate earned credits. Effective date.

SB 1213 modifies Oklahoma's inmate earned credit system by removing minimum incarceration time requirements (previously 3 months for Class 3, 8 months for Class 4) for assigning credit levels. It establishes new monthly credit rates based on an inmate's criminal history: inmates without prior felony convictions receive higher credits (Class 3: 45 credits/month, Class 4: 60 credits/month) compared to those with felony histories (Class 3: 33 credits, Class 4: 44 credits). The bill affects all state prison inmates by changing how their sentence reductions are calculated through earned credits. Key provisions include updating credit assignment criteria, requiring gender-neutral language, and specifying that credits cannot be earned for certain offenses like killing law enforcement officers. The changes apply to all inmates assigned to Class Levels 2-4 under the Department of Corrections' updated policies.
