Reviewer(s) - Jeff MacSwan, Arizona State University
In this review, MacSwan indicates that the report is riddled with flaws. He points out that neither the data presented nor could the author's analysis of that data support the conclusions drawn in the report. MacSwan indicates that the report suffers from poorly sampled data, inaccurate descriptions of district-level policies, failure to account for alternative explanations of observed changes in district testing data, and lack of any serious analysis of the data presented.
