How NWEA measures growth using the end-of-course tests.

The math 6+ and end-of-course math tests use the same RIT scale. The end-of-course math tests in algebra and geometry only measure one goal strand, whereas the 6+ tests measure multiple goal strands depending on which standards alignment your organization uses. Since they are on the same scale, MAP Growth reports measure growth for students who take end-of-course tests the same way as we would with MAP Growth tests in any other subject: by subtracting the RIT score for the test taken at the beginning of the comparison period from the the RIT score for the test taken at the end of the comparison period.

So, if you are comparing fall to spring growth, and the students took the math 6+ test in fall and end-of-course algebra in spring, then their growth will be calculated by subtracting their fall score (in math 6+) from their spring score (in algebra).

Remember that only one test in a subject is considered valid for growth, so if a student takes both the math 6+ test and an end-of-course test, only one of those tests (the test with the lower standard error of measure) will appear valid on reports.
