While going through his lesson plans, Iruka realizes that his students could use some practical experience with basic shinobi skills. So he comes up with a lesson on infiltration and observational skills.
The entire class is given an infiltration mission. The place they are supposed to infiltrate: Their own class. For one month, every day, at the end of school, each student is given sealed orders. The next morning, the students go to school, break away from their classmates, henge into the student their orders designated, and go to class. For the duration of the day, they must act like that student, and treat other students the way that the person they are impersonating would treat them. They are also instructed to watch the rest of their classmates and figure out who is impersonating who. At the end of the day, the students turn in reports in which they state who they think is who and why (And just to confuse things, roughly once a week, one randomly selected student is ordered to impersonate him/herself).
In theory, since these kids have been taking classes together for years, they should know each other well enough to make this possible. In practice, that's not the case. Instead of acting like the people they are impersonating, they act like their perception of that person. As such, the various kids are given a harsh lesson in what other people really think of them.
While the point of the lesson is to learn about how to disguise themselves and spot disguises, Naruto and the rest of the gang are going to learn a great deal more about themselves.
This is meant to mostly be psychological, there is potential for humor involved (Such as Hinata trying to act like a Sasuke fangirl, or Hinata being Sasuke and realizing that one of the 'fangirls' is Naruto).
