"Those SCAT scores seem to pretty accurately mirror the MAP scores from this spring, so unless you have additional data, I'd have to think that they are accurate."

HowlerKarma, these may be the same percentile, but the SCAT is normed 2-3 years out of grade level. I would assume the 77%ile on the SCAT reflects a much higher score than the SCAT. However, my understanding is that the SCAT is a mix of aptitude/achievment, while the MAP is strictly an achievement test.
