The authors evaluate and advocate the need for comprehensive sexuality education that meets the unique needs of youth who are deaf or hard of hearing, while calling for the expansion of teacher preparation in this critical area. Effective comprehensive sexuality education is designed to prepare young people to become more comfortable with, and informed about, their sexuality. Teachers and parents are key adults in this process. However, the responsibility for preparing teachers to handle sexuality education lies with both the postsecondary teacher preparation program and the administrative team at the individual school; their willingness to provide comprehensive training, current resources, and continued support are crucial to the success of any comprehensive sexuality program. In the individual school, effective guidance of youth who are deaf or hard of hearing in making appropriate decisions about their sexuality is built upon a team that includes not only school staff, but also parents and deaf adults in the community.
