The content of these units explores many sensitive topics, such as prostitution, sexual-based violence, gender-based violence, and slavery. Many of the units also contain explicit, mature language and ideas. Your students and their parents will have varying degrees of comfort with these issues. Your class may include victims or family members of victims as well. We have found it helpful to set a tone from the beginning of a class regarding the types of mature, complex, and potentially explicit issues that you will be discussing, and clarify that you expect the class to explore these issues in a mature fashion.
