Other The ISU Faculty Senate unanimously approved the following resolution on November 8, 2016:
That the Faculty of the Iowa State University Senate stand united for the ideals of diversity and inclusion at our university. We welcome all students to learn to the best of their abilities on our campus in an environment free from racism, sexism, bigotry, harassment, and oppression. We uphold these ideals ourselves, and strongly encourage our colleagues across the university both to uphold these ideals, and to teach them when appropriate to our students as a way to move human society forward.
