Administrative Experience?

[AlphaO]

I am going after some HR jobs and I graduated with a degree in Psychology. I don't want to go into social work or counseling, I really want to break into the corprate world.

All of the positions I am interested in are entry level but require "administrative expreience" (1 to 3 years). I have work in an office enviornment and have 3 years expreience doing various things throughout the comapny. I feel like "administrative expreience" is such a broad term and I do not know how to change my resume so it looks like I have that experience. Can anyone help me with key words or help clue me in on what a potential employmer my be looking for with that term?

Thanks!
