I am a parent of a 99 percentile reader. These Map scores do flucuate a lot and I have read that one of the problems with these tests is that children sometimes learn in chunks and in no particular pattern. These tests arbitrarily assign difficulty to their questions. I have never been given enough information from the school about these tests and my child tells me that that at the top of the test, she receives the same questions year after year. Does any one know what the top score is. My child received a 265 this year after staying at the 235 to 240 level for 2 years. I was never sucessful at getting proper reading instruction through the school. I buy lots of books and visit the library regularly.
