I think MAP "typical" growth is around 6 or 7 points a year - it should say on her NWEA progress report that the school should send home. If not, they can easily print it out and give it to you if you ask. I think even with just typical growth, she should be further along unless she is not taught anything at her level. I would be concerned if she was not making steady growth in each year. If she does not test well, that may explain it too, but MAPs are not timed so she should be allowed all the time she needs. You might also want to see how she did in the subtests of the reading portion to see if you can pinpoint any issues.
