While MAP testing may not be an indicator of "giftedness" per se, it can be a reliable indicator of a child's mastery in a given subject area. In some cases the MAP score may reveal that the child has the readiness and ability for advanced curriculum.

The readiness and ability for advanced curriculum, the need for more academic and intellectual challenge in order to keep learning and growing, is what schools may increasingly rely on (as opposed to a "gifted" designation or label). This may be related, in part, to lowered standards which may result in 15-45% of students working one or more grade levels ahead beyond the standard curriculum, although a much smaller number may have an IQ in the "gifted" range. Thinking along those lines, this old post may be of interest.
