If I were on the school board, in this day and age of litigation, yes, I would require demonstrated proficiency with a firearm before allowing staff to carry. Don't like it, don't carry on the job or take a job somewhere else.
I have been around ranges long enough (35+ years) and people who think they know how to shoot well enough to know... There are a lot of people out there that should not have firearms. Or, more precisely, who are in desperate need of training and regular practice. Someone who has sat through all of 4 hours of classroom training and made a couple of trips to the range, fired a grand total of a thousand rounds and got their CC permit? They are not safe in a crowded, stressful situation.
So yes, the right to keep and bear arms is fundamental. I'm not advocating the government infringe on that at all. An employer - ie. the school district - in a voluntary situation (your employment) yeah, I have no problem with that. Employees routinely sign NDAs giving up free speech as a condition of employment. Empoloyees routinely consent to random drug screens or personal searches giving up 4th amendment protections as a condition of employment. If a company is going to spend a hundred million on R&D, yeah, they should be able to keep that to themselves. If you're going to be piloting a few hundred people around the sky, yeah, you better be drug-free. You going to be shooting in a tense situation around a hall/room full of kids? You better be a good shot.
You can read how Texas does it by clicking on the link on post 14. It speaks to the training of employees in school allowed to carry.
I do.
If you worry more about lawyers and litigation than children, I will question it.
So, hero from the range... who gets to have firearms?
Here's a hint.... if anyone is shooting at a school, it's an unsafe situation.
Who is going to require your standards? Government schools.
