The Safe Schools Improvement Act (SSIA) would amend the Elementary and Secondary Education Act (ESEA) to require school districts in states that receive ESEA funds to adopt codes of conduct specifically prohibiting bullying and harassment, including on the basis of race, color, national origin, sex, disability, sexual orientation, gender identity, and religion. SSIA would also require that states report data on bullying and harassment to the Department of Education. The Department of Education would then be required to provide Congress with a report on the state reported data every two years.
