Peer-educators should be allowed space to expand their confidence in their abilities to teach and learn. Leading classes toward the beginning of the semester will jump start their relationships with students so they can make the best impact.
A peer presence in the classroom gives students a sense of comfort and familiarity that could quickly become unproductive. Peer-educators need to feel comfortable saying "no" to students and remember where responsibilities lie when it comes to coursework, attendance, and overall engagement with peers and material.
New peer-educators should build off practices of those prior, but also keep track of new ideas they bring to the role. Compiling small innovations will help the instructor decide what is most productive and help repurpose the role for the future.
