Do you have her actual scores? Hopefully you are in a school that will utilize the data and place her with kids scoring in the same RIT bands as her! What MAP tells us , is what the child already knows with a 75% accuracy rate. It is not based on a childs current grade. It is an adaptive test. If the child answers correctly, the next question becomes a bit harder. If the child answers incorrectly the score goes down.
You can check out the bands on this site
