Ahh, "show your work" hits again. If she got all the answers correct, then I would be in there arguing that. It's not like it was homework, where she could have asked someone for the answer or looked it up online or in the back of the book. It's a test, which presumably was given in front of a teacher, so if she got the answers right, she obviously knows how to do the problems. She may not do it the same way as what they want in the explanation -- which is a good reason to let her take the class, so she can learn how THEY want things done as well as move ahead.
I can practically guarantee you that 252 MAP score in 4th grade is one of the best in the school, not just top 25%. It would still be above 99th percentile for 6th grade.
