Interview help please

[CalmerChamaeleon]

I have an interview on Monday for an acting deputy post at my school. One part of the interview is to take something along to show/talk about that shows my qualities as a teacher. I have a couple of ideas, but not sure if I'm on the right track. What do you think?
a) subject leader file to show I keep up-to-date/am organised/have leadership skills
b) childrens' anecdote poems - quite humorous and refer to me (in a good way!)
c) examples of planning and all
d) something else
I'm usually full of ideas for other people, but this one has me stumped! I'd really appreciate some advice.
