These are super simple, but really important for a photography class in high school.
Since so many photo shoots are done outside the classroom (in the halls/outside on school properly) these are really helpful for students to have on hand.
I laminate them and put them on laniards, and every time the students are shooting outside the class, I get them to take these to clarify for any admin/anyone else who they are and why they're out of class.
It also makes students take more responsibility for their actions when outside the class.
Just an easy way to track as well.
Enjoy! Hope it helps.
