1. Overview of Split Sentencing Research October 25, 2006 Mark Rubin

2. Presentations given to subcommittee Exploring the Relationship between Split Sentences and Probation Recidivism in Maine - July 27, 2006 Who gets a Split Sentence in Maine? - August 2, 2006 Who is getting revoked on probation? - September 21, 2006

3. Study Parameters/Methodology Examined 2004 and 2005 populations of individuals entering probation via : –Split Sentence (spent some time in jail or prison just before entering probation –Straight Probation (received a sentence of probation without any jail or prison time

4. Exploring the relationship between sentence type, risk, recidivism, and revocations Examined the following variables in the analysis: –Risk Level (LSI-R scores) –Crime type (MEJIS index and Class) –Region –Jail/Prison split –Number of Priors –Demographic variables (gender, age, education, race,et al.) –Criminogenic factors, including criminal histories (number of priors) –Shock Sentence –Probation revocations by type of offense (new crime vs. technical) –Revocations by risk level –Revocation information by sentence type

5. Who gets a Split Sentence?

6. Twice as many split sentenced offenders entered probation in 2004 and 2005 as those with a straight probation sentence

12. Exploring the Relationship between Split Sentences and Probation Recidivism

13. Sentence TypeRecidivism Rate Split Sentence30.4% Straight Probation20.5% Overall26.9% *=Statistically significant difference between recidivism rates Split Sentenced probationers have higher recidivism rates than probationers receiving a straight sentence

14. The data suggests first time/one time offenders may have worse outcomes when receiving a split sentence versus straight probation Number of PriorsStraight Probation R.R.Split Sentence R.R. 0-1*17.7%27.4% 2-427.5%30.8% More than 435.7%42.7% * No statistical difference between recidivism rates, due in part to small samples

15.

16. Offenders convicted of certain crimes appear to have statistically higher recidivism rates when receiving a split sentence Crime (from MEJIS Index)Straight Probation R.R.Split Sentence R.R.

17. Recidivism rates are higher for shock sentences than straight probation, especially after 30 days. Sentence TypeRecidivism Rates Straight Probation20.5% Split - 7 and less27.9% Split - 8-14 days21.0% Split -15-3026.9% Split -31-6035.8% Split -61-9033.7% Split of 90+ days34.8%

18. Concluding Thoughts Split Sentence probationers appear to have higher recidivism rates than straight probationers even after accounting for specific characteristics. However, sentencing practices are at best weakly related to a recidivist outcome. Other factors play a role, such as AFA, Priors, Current Age, Education, Married. It appears that split sentencing has a more profound impact on lower risk offenders as to whether they recidivate.

19. Who is getting revoked?

20. Revocations rise dramatically as risk levels rise LSI Rating (includes overrides)Revocation Rate Administrative14.4% Moderate36.4% High56.0% Maximum82.4% Total33.6%

21. The higher the risk level of the offender the more likely s/he is to be revoked for a technical violation LSI Rating (includes overrides) Revoked for a new crime Revoked for a technical violation Administrative61.2%38.8% Moderate48.7%51.3% High43.7%56.3% Maximum29.0%71.0% Total48.5%51.5%
