Racial and ethnic disparities in criminal justice have received increasing scrutiny recently. Little attention, however, has been directed toward understanding inequality in the area of probation. The current study addresses this dearth through two analyses of 14,365 probation cases. The first involves a logistic regression analysis, which examines race/ ethnicity against probation failure. Using probation success as a control outcome, the second analysis uses a multinomial regression to examine the effects of race and ethnicity across four types of probation failure-administrative failure and revocations resulting from technical violations, new felonies, and new misdemeanors. Across both models, racial/ethnic categorization were found to be significantly and positively associated with probation failure outcomes. In addition, the standardized coefficients indicate that Black and Hispanic racial/ethnic categorization presented a moderate to strong effect sizes across outcomes studied. The strongest effect sizes for these two variables were found in the multinomial model within the administrative failure outcome. Across both models, other racial categorization (Asian/Pacific Islander or Native American/ Alaskan Native) was statistically significant but consistently produced some of the weakest effect sizes. Potential explanations for these findings are offered along with a discussion of study limitations, future research suggestions, and policy implications.
