DIBELS Thoughts?

I am attaching a Research Paper I am using for part of my literature review for my Masters Program and I got to tell you that this has really got me worried about if DIBELS is the way to go when identifying future at risk students. I have always thought the Retell Fluency is not a true indicator of comprehension and this study seems to suggest not only that, but the PSF and the NWF are not good indicators of issues either.

I would love to have a discussion with you all to see how you feel about DIBELS
