While being a “Prior Felony Offender” changes who sentences you, reaching “Persistent Offender” status changes the actual length of time you can spend in prison. Under RSMo 556.016.3, Missouri law mandates a “step up” in sentencing, requiring the court to treat a lower-level felony as a more serious crime for punishment purposes.

1. Defining the “Persistent Offender”

A person is classified as a “Persistent Felony Offender” if they meet either of the following criteria:

• They have been found guilty of two or more felonies committed at different times.
• They have been previously found guilty of a “dangerous felony” as defined in RSMo 556.061 (there are 30 such “dangerous felonies“)

Like the prior offender status, these previous findings of guilt must have occurred before the date of the current offense. (RSMo 556.016.6)

If someone who was facing changes for possessing drugs on Jan 1, 2026, and while that case is pending gets arrested and changed again for possessing drugs on March 1, 2026, that first case can’t be counted as a “prior offense”

2. The “+1” enhanced sentence

The most critical impact of a “persistent felony offender” status is found in RSMo 558.016.7 – the sentencing range for imprisonment in the Department of Corrections (DOC) is one class higher than the actual charge.

This applies to Class B, C, D, and E felonies:

• Class E Felony (normal range of 1-4 years in DOC): Sentenced within the Class D range (1 to 7 years).
• Class D Felony (normal range of 1-7 years in DOC): Sentenced within the Class C range (3 to 10 years).
• Class C Felony (normal range of 3-10 years in DOC): Sentenced within the Class B range (5 to 15 years).
• Class B Felony (normal range of 5-15 years in DOC): Sentenced within the Class A range (10 to 30 years or Life).

3. Loss of Jury Sentencing

In addition to the increased prison range, a persistent felony offender loses the right to jury sentencing. Under RSMo 558.016.7, the court “shall sentence” the defendant. This means the jury decides guilt or innocence, but the judge determines the specific number of years within the enhanced range.
