This is an odd characterization of the Stop the Bleed program. Largely I’ve seen it targeted at adult and people in industries at particular risk, rather than children in particular.
That said I could get behind a CPR/AED/StB program being standardized for a high school course level. These types of programs tend to take a little amount of time to teach and can buy enough time for EMS to arrive. Although 8-9 yr olds seems like a bit young.
