Which sentencing method is often described as "20 years to life"?

Indeterminate sentencing is a method where a range of time is given for a sentence, such as "20 years to life." This approach provides flexibility in sentencing, allowing for the possibility of parole based on the behavior and rehabilitation of the offender while they are incarcerated. The minimum term ensures that the offender serves at least a certain amount of time, while the maximum term reflects the seriousness of the crime, allowing for release if the individual shows signs of rehabilitation before reaching the maximum sentence.

This method contrasts sharply with determinate sentencing, which involves fixed sentences without the possibility of parole, and with mandatory sentencing, which enforces minimum sentences for certain crimes regardless of circumstances. Discretionary sentencing grants judges the ability to choose a sentence within a range but does not typically involve a broad range like "20 years to life" that is characteristic of indeterminate sentencing.
