Section 6 of the U.S. Flag Code addresses the Time and Occasions for Display. In this section the Flag Code names the particular days the flag is to be flown—New Year’s Day, Washington’s Birthday, and others. I wrote about that in Designated Flag Flying Day from the US Flag Code.
It also gives details on other locations that should display the United States flag daily. Sub-sections (e), (f), and (g) tell us the flag is to appear at public institutions, polling places, and schools.
(e) The flag should be displayed daily on or near the main
administration building of every public institution.
(f) The flag should be displayed in or near every polling place on
(g) The flag should be displayed during school days in or near every
On or near the main administration building would include City, County, and State offices, as well as the administrative offices for school districts. This includes all tax funded facilities, and in Texas, the flag is always flying at these buildings.
Every polling place on election days is easy in Texas. I don’t know about other states, but elections are almost always conducted in offices that fit the above description. Elementary schools are very popular because of their locations in neighborhoods.
In my experience every school, in our state, flies the American and Texas flag. Most have fantastic flag poles soaring above the entrances with flags flying as the students arrive for the day.
