What materials will you have available to support student editors in your program? Support for student editors can come in many forms — human (Ambassadors, a Teahouse-like page on-wiki), text (on-wiki trainings and help pages), video (screencasts), or printed materials (brochures, handouts). There's not one right answer for how to best support students in your program; instead, think about what will best help your students and create a plan for developing those resources.
The Education Portal Tips and Resources page contains files used by other programs to support students; review and see if some would be useful for you to translate and use as well.
