Does the MAP Growth test measure a student's ability level, or their achievement? What's the difference?

MAP Growth tests measure a student's academic achievement, not his or her ability. Achievement on the NWEA tests is evidence of what a student has learned and can do with approximately 50 percent accuracy within a subject area. NWEA calls this the student's instructional level. Another way of understanding instructional level is parallel to a student's zone of proximal development which states that a student has acquired a body of knowledge that prepares them for the next concept that will be introduced. This should not be confused with mastery level.

Ability describes a student's capacity to learn, independent of what has been achieved. NWEA's tests and reports do not measure or report a student's capacity or ability to learn. NWEA tests are primarily designed to inform the teacher where to begin instruction, or what the student is ready to learn. You can use the learning continuum to see what topics the student is ready to learn based on their RIT score.
