Question
Why do I see the same growth projection for all my students?

Answer
While we would typically expect to see that lower starting scores have a higher growth projection, this is not always the case. Where the growth projections for students are the same or very similar across the achievement levels, this is not an error. This flattening of growth is a commonly observed pattern, not only for MAP Growth tests but for other tests as well. We first saw this pattern of flat growth in the 2008 norms, and it was also present in the 2011 and 2015 norms. These norms studies use different methodologies, but the pattern of flat growth is still found within the data.

NWEA does not have an explanation for this behavior, only that it is what we have observed. For specific information about flat growth for 5th grade mathematics, see Why do I see the same math growth projection for all of my 5th grade students?
