And I think a portfolio just means a few samples of a kid doing something as good as a kid a few years older. But they want something the kid does, not something you told them to do so they know they weren't just following directions. Some common items I've seen mentioned are things like original writings or a video of a kid describing their favorite subject.
Eta: I googled. A portfolio needs 4 pieces of something 2-3 years advanced and it can include assigned work as long as they did it theirself.
