What does a "portfolio" mean?

Question

I have been looking into applying for technical theatre/stage management courses. Many ask you to bring a portfolio to interview. What would this contain, and what form would it take? Particularly for courses for mainly/only stage management...

Answer 1

It would be a collection of your designs, working drawings, floor plans, light plots, etc. Usually contained in a carrying case called a portfolio.  Available at art stores.
