In 2015, Congress added a provision in the reauthorization of the Elementary and Secondary Education Act of 1965 (ESEA) to help protect students from sexual abuse and misconduct in schools. ESEA Section 85461 requires states to have in place laws or policies that prohibit schools, local school districts, or state education agencies (SEAs) from assisting or "aiding and abetting" school staff in obtaining a new job if they are known or believed with probable cause to have engaged in sexual misconduct with a student or minor in violation of the law. This study examined states' development and implementation of laws and policies to prohibit aiding and abetting educator sexual misconduct in schools. The study also sought to describe the challenges states have encountered in implementing the requirements of Section 8546 and how they have addressed these challenges. The Department sought to understand how states are addressing implementation of the provisions in Section 8546 in order to inform the Department's technical assistance efforts to help SEAs with this section of the law. The study addressed four main questions: (1) To what extent do states have laws, regulations, codes of ethics, and/or policies that prohibit assisting or aiding and abetting the employment of school staff, contractors, or agents who have engaged, or where there is probable cause to believe they have engaged, in sexual misconduct with a student or minor?; (2) How did states develop laws, regulations, codes of ethics, and/or policies to address Section 8546?; (3) How are SEAs implementing laws, regulations, codes of ethics, and/or policies that prohibit aiding and abetting? and (4) What challenges have SEAs faced in implementing state laws or policies required under Section 8546?
