After reading the modified version of "The Giver" in my self-contained English Literature class, I had students take a visually based exam to answer basic questions about the book. This is a great data point for students with IEP goals that focus on answering factual questions about a book and identifying story elements. For the story arc, you can google one that works for you. There are a ton of free ones out there.
