This is related to the "what to say in a diversity statement" question, but I'm asking something slightly different:
Who reads a Diversity Statement in a faculty application (exact sciences/CS/math) at an R1 institute?
Anticipating answers like "anyone on the department can read it", let me be more specific: Who usually reads diversity statements and takes relevant decisions on their basis? Is it faculty members? Is it administrators? Are they generally used as a first screen, as an appendix to the teaching statement, or as a tiebreaker?
