A report from the Heritage Foundation objects to the increasing number of Chief Diversity Officers (CDOs) emerging on public school districts’ administrative teams, and claims that districts with CDOs have failed to close student achievement gaps in standardized testing outcomes. The report also promotes test-driven accountability at the expense of the learning needs of pre-K-12 public school students. The conclusions drawn by the report are based on flawed research, and thus it fails to provide valuable guidance for policy or add to the research base on closing achievement gaps or on diversity, equity, and inclusion in K-12 settings.
