As you already know, 232 is a strong MAP Reading score for 4th grade winter. At 97 percentile, your DS should qualify for most GT reading classes (except for those which have a strict 98 percentile or higher cut-off). However, remember that MAP is strictly multiple choice and untimed so does not address output and efficiency issues. Furthermore, local percentiles may vary considerably from national ones. You really need to sit down with your school or district to figure out the lay of the land.
