I'd like my portfolio back, please.

We turned in our portfolio and evaluation June 18. Today, I went to the school to turn in our affidavit for the coming school year. I asked about the portfolio. The secretary asked "Didn't he call you yet?" I told her he didn't. She said he will when he looks through it. I'm wondering how long schools usually keep these things. I would like to officially wrap up the school year, and I'm feeling antsy about not having posession of it. I copied the essentials, but not everything.
