I'm not a homeschooler either but I use the MAP information for afterschooling. One of the things that's helped me is to understand the MAP results are presented with a range of skills and concepts to enhance, develop, and introduce. The skills and concepts to enhance means there's a 73% probability the students would correctly answer items measuring these concepts and skills, develop is 50% probability, and introduce is 27% probability. Since many of us deal with perfectionism, our typical expectation is set to operate around 95-100% probability. I think this may explain some of the disconnect between what we think our children are ready to learn and what the MAP results indicate they're ready to learn.
