What do you expect the student editors participating in your program to do? Student editors may or may not follow patterns commonly seen among other new editors. Many will do essentially the bare minimum for what they've been asked to do, and will not do any significant editing until a few days before the deadline their instructors set. A few student editors might take to Wikipedia and start making copy edits or other contributions outside of what they're being asked to do for class — and these may be potential long-term Wikipedians and future Ambassadors. But don't have unrealistic expectations about what student editors will contribute — remember, they're busy with school and may or may not have any interest in contributing beyond what they're being asked to do for class.
