   Risk-needs assessments (RNAs) assist correctional staff in assigning  Received 7 June 2023

   Unfortunately, females are frequently overclassified, relegated to a  Juvenile justice; risk-need
   category higher than their risks indicate. Using ridge and mixed assessment; recidivism;

   accuracy of the  Modified Positive Achievement  Change  Tool
   (MPACT)  comparing  three  common   assessment  development
   methods via a 10-state sample of youth (N-241,596) across multi-
   ple justice settings. Findings demonstrated recidivism rates vary
   substantially by gender and bias/overclassification is likely for
   assessments using a gender-neutral approach. Tools that oversam-
   ple females, or attempt equally weighting, have similar issues.
   However, gender-specific methods create prediction parity, root-
   ing out overclassification. Study takeaways include the need to
   evaluate tools for overcdassification, methods of eliminating gender
   bias, while achieving strong predictive validity in development of
   the MPACT





Introduction

Risk-needs  assessments  (RNAs) are tools commonly used by justice agencies to stan-
dardize  intervention provision, wherein  individuals with the same   risk score possess
the same  probability of recidivism and  hence, should  receive a similar level of super-
vision  and   programming. RNAs traditionally gather offense history and use
semi-structured  interviews  to score  individuals risks of recidivism, which  are then
summed to create a composite risk score.   Thresholds  (or cut points) are then set to
divide the  scale's distribution to form  risk level categories (RLCs). The  Risk-Need-
Responsivity  (RNR) model  outlines the  use of RLCs, where  higher  risk individuals are
to receive  a greater  intensity of supervision  and   programming,   while  lower  risk
