Though governmental departments, organizations, and educational institutions are capitalized, the positions or titles of the people who work in or represent those groups are not, unless that person's position in the group is used as a title in front of the person's name (Senator Bob Kerry).
Note: It is only acceptable to capitalize the word "president" when speaking about the President of the United States (and, even then, it is the writer's choice). Do not capitalize it when referring to presidents of universities and organizations.
Note: Do not capitalize common nouns to make them seem important
or to make them stand out, because you will likely confuse
the reader. Use boldface or italics instead.
