The Clery Act is a federal statute that requires colleges and universities that participate in federal aid programs to maintain and disclose campus crime statistics, to put it briefly, Title IX cases, because schools to be in compliance with Title IX need to report certain statistics to the federal government and also just in an overall sense need to comply with Title IX to continue to receive federal funding from the government. This is the reason why Title IX and the Clery Act are intertwined.
Title IX itself in part is a federal law that's intended to prevent and address campus sexual misconduct. Campus sexual misconduct can include various forms of misconduct, nonconsensual sex, sexual assault, sexual harassment, crimes of a different nature also, or at least for the school policies. That's why there's the overlap between Title IX and the Clery Act where the college or university would have to report certain information to the government at the given time. An experienced attorney advisor can help if you're accused of a Title IX offense, they can help protect your rights and interest through the process.
