No, I don't think MAP is a measure of IQ. It's a measure of achievement. That being said, both of my DYS have always had very high MAP scores, often spiking RIT scores well, well over the minimum 99% mark. I believe that MAP itself talks about scores above the 95th percentile as being an indicator of giftedness. I believe that many gifted students who are sufficiently exposed to higher-level material, and who are not struggling with a LD, also demonstrate this type of achievement.
It sounds like your DD attends a school with a least one teacher trained in teaching gifted students, which is wonderful! It may not be necessary to further ability test her to confirm that she needs something different to help her grow. I would not bother with further testing, unless she needs it.
