An awareness of gender can help explain how and why girls behave in different ways and what, if any, misperceptions of girls’ behavior—rooted in race and/or gender biases—may exist among system actors or within girls’ families. It also empowers stakeholders to analyze how policies and practices may be negatively or differently impacting girls and to address disparities that are missed when systems assessment and reform do not include a targeted gender lens. This guide, which supplements Vera’s Toolkit for Status Offense System Reform, aims to help system leaders and staff do just that.
