Over 20 years has passed since the principles of gender-responsive correctional strategies were published in a foundational report in the U.S. These practices acknowledge the unique characteristics and life experiences of justice-involved women, have undergone rigorous empirical testing, and are shown to effectively reduce women's recidivism. In part, they supported the United Nation's adoption of minimum human rights afforded to women serving custodial and non-custodial criminal sentences. This paper presents updated research evidence that continues to amplify the need for gender-responsive principles and practices, including the role of victimization in girls' and women's offending trajectories and the intersection of relationships, relational identity, and trauma as key drivers for justice involvement. Further, because the perinatal needs of justice-involved women are a frequently overlooked area of inquiry among the gender-responsive literature, this scholarship is also summarized using a reproductive justice framework. Finally, we illustrate the impact of gender-responsive scholarship by sharing some of the practice and technology innovations that have emerged, while acknowledging there is much yet to accomplish.
