Oh, yes there is!  There are at least three times it happens:

1. Students do it in school, albeit privately, right before a test;
2. The school community does whenever there’s a tragedy – a death, a shooting, an act of terrorism, etc.; and
3. Teachers do it every day, since, oftentimes, it’s all they can do for some of the parents of the children they teach who refuse to realize that their little ones may have behavioral issues or other diagnoses, or put  children AND teachers at risk by not wanting their children to have to wear masks.

Can you think of more?

At least more and more states think our nation’s public schools should remind students about trusting in God: https://www.washingtonpost.com/local/education/does-in-god-we-trust-belong-in-schools-more-and-more-states-say-yes/2018/12/01/d846f870-e863-11e8-b8dc-66cca409c180_story.html
