There are also several federal statutes for which the EOS has enforcement authority, although only after a referral from another government agency. Those statutes, generally, prohibit the recipients of federal financial assistance from discriminating on several bases (Title VI, Title IX, Section 504, Title II of ADA, and IDEA).
You should tell the School to Careers coordinator at your school, along with anyone else who has authority to make changes to this program (such as the principal of your school). Check your school's policy for addressing complaints for sex discrimination, which every school must have.
Your school must either help fix the problem at your internship site, or end their partnership with the local business.
The Department of Education's Office for Civil Rights ("OCR") has primary responsibility for investigating Title II complaints.
Title III of the ADA prohibits discrimination on the basis of disability in public accommodations, such as schools, operated by private entities. The Department of Justice has primary responsibility for enforcing Title III as it relates to education.
The EEOA also requires school districts to take action to overcome students' language barriers that impede equal participation in educational programs.
The Department of Education's Office for Civil Rights ("OCR") has primary responsibility for enforcing Title IX's provisions with respect to recipients of federal education funds.
