How do you feel about the DMA assessments and interventions?

I am so pleased to have this wonderful tool as a resource in my district.  As a Math Coach and the leader of the Math RtI Committee for our district, I am looking for tools to help identify students who struggle with Mathematics and require Intervention.  Not only does this tool give us the ability to identify these students, but the Intervention Handbook then helps us to know how to remediate these students.  The price is very reasonable, and the materials are all there for me.  I don't have to pull from here and dig around to find what I need!  I have also been told by several of the Intervention Specialists that the DMA is a huge asset in the writing of IEP goals for their Special Education students since it pinpoints areas of improvement for these students.                                                                                                                                 ~  District Math Coach
