Applying Evidence to Sex Offender
Management
• A subset of sex offenders is a particularly high
risk to sexually re-offend
– CDCR supervised 1,906 High Risk Sex Offender
(HRSO) parolees as of January 1, 2005
• These offenders may commit extremely
damaging crimes of particular concern to the
public
• Global Positioning System (GPS) monitoring is a
fast-proliferating but little evaluated tool for sex
offender supervision
CDCR Will Have 500 GPS Units in
Place Statewide by July, 2006
Program Goals
1. Reduce sexual and violent criminal behavior of
HRSO parolees
2. Improve detection of violations of parole conditions
and patterns of risky behavior through enhanced
supervision of HRSO parolees
3. Increase HRSO parolee compliance with conditions
of parole
4. Identify or eliminate parolees as suspects in new
crimes by sharing GPS information with law
enforcement agencies
5. Develop partnerships with local law enforcement to
reduce crime
CDCR Will Have 500 GPS Units in
Place Statewide by July, 2006
Program Components
• Reduction of caseloads for GPS agents to 20:1
• Screening of HRSO parolees to determine their risk to
re-offend, and targeting GPS monitoring to the highest
risk parolees
• Enrollment and orientation of parolees into the
parameters of GPS monitoring
• Integration of active GPS monitoring information into the
intensive supervision regime
• Synthesis of parolee GPS and law enforcement crime
data
CEBC Evaluating the GPS San
Diego County Pilot
• San Diego pilot placed the first California
parolees on GPS in June of 2005
• 80 GPS-monitored HRSO parolees in San
Diego County
• Research team meets regularly with the
San Diego GPS implementation team
Research Questions
• What motivated the GPS HRSO program/what is
the program design?
• What are the characteristics of the offenders
who participated in the pilot/how do they
compare with other HRSO offenders in San
Diego and the statewide sex offender parolee
population?
• What were the implementation experiences?
• What impact did GPS have on system and
offender behavior?
• What were the costs of the pilot program?
The Center Will Produce Three
Research Products
1. Program Model Description
2. Implementation Analysis
3. Outcome Analysis

• Descriptive analysis of parolees placed on GPS
compared to San Diego County and California
sex offender parolees
Outcomes for GPS Group Will Be
Compared with Outcomes for Non-GPS
Parolees
• Treatment Group
– 94 HRSO parolees placed on GPS monitoring in San
Diego County from June through November of 2005
• Control Group
– 116 parolees on HRSO caseloads in San Diego
County from June-November of 2005, but not placed
on GPS monitoring during that interval
• One year observation period, concluding
December 1, 2006
Preliminary GPS Pilot
Implementation Observations
• GPS information is labor-intensive to
utilize
• Program effectiveness is impeded by
shortcomings of ancillary technologies
• Bargaining unit participation preserves
programmatic flexibility
Evaluation Next Steps Involve
Answering Two Key Data
Questions
1. Can the data on the relevant parolee
characteristics and outcomes be
abstracted from existing data?
2. Are the identified treatment and
comparison groups sufficiently similar?
