Corrections officials adopted new criminal sentencing rules on Friday that aim to trim the California prison population by 9,500 inmates after four years, reported Fox News.

GovXThey include steps like reducing inmates’ sentences up to six months for earning a college degree and by up to a month each year for participating in self-help programs such as alcohol and substance abuse support groups and counseling, anger management, life skills, victim awareness, restorative justice, and parenting classes.


Virtually any inmate except those on death row or those serving life-without-parole sentences are eligible to earn the credits and lower their sentences.

It’s the latest step in a years-long drive to dramatically lower the state’s prison population in response to federal court orders stemming from lawsuits by prison advocates and pressure to turn away from mass incarceration.
