This document reports the outcome findings for Phase II of the Georgia Cognitive Skills Experiment. It is the fourth and final report of this project. Both Phase I and Phase II of the Georgia Cognitive Skills Experiment utilized a randomized controlled experimental design to compare outcomes for offenders who participated in the Cognitive Skills Program to those who did not. The central question of the Phase I study concerned the overall effectiveness of the Cognitive Skills Program. Phase II expanded on this inquiry to determine whether: 1) the program was more effective for some types of offenders than for others, and 2) specific program characteristics could improve offender outcomes. The following sets of research questions were addressed in Phase II: 1) What was the overall effectiveness of the Georgia Cognitive Skills Experiment? How did recidivism rates and test scores for offenders participating in the Cognitive Skills Program compare to those who were assigned to the comparison group? 2) Did the program benefit some types of offenders more than others? Did some types of program participants actually do worse than those who did not participate? And, 3) What sorts of program and facilitator characteristics differentiated the most effective cognitive programs from the least effective? Do such factors as group size, program completion, and facilitators' skills impact offender recidivism?
