Prior to October 1995, the amount of time served by inmates sentenced to state prison was dictated by several types of gain time and provisional credits that were in place due to past prison overcrowding. The 1995 legislature passed into law the Truth in Sentencing Act that requires all offenders sentenced to prison to serve a minimum of 85% of their court-imposed sentence.
Any offenders whose crimes were committed on or after October 1, 1995, are now subject to this requirement and these offenders must serve, at minimum, 85% of their sentences. Inmates sentenced prior to this date are not required to serve 85% of their sentences, and will therefore have a lower overall percentage of sentence served.
Inmates released during FY 2014-15 served an average of 85.6% of their court-imposed sentences, the same average as last fiscal year.
