Ask a current middle or high schooler if they have. Probably, the answer will be yes. Source: I know an awful lot of teachers. IMO the drills are dumb as hell and indefensible considering how traumatic they are (reports of teachers breaking down crying afterward, let alone students) and how unlikely mass indiscriminate shooting[0] is at a school, even in the US. The old less-insane and less "real" teacher-only drills were probably enough, considering how harmful this alternative is. [0] A distressingly large percentage of students will be near some kind of gunfire while at school, yes—a whole lot smaller percentage will experience the sort that these drills address. The more common variety that way more will hear or see are targeted (gang, grudge, whatever) shootings on or near school property, not the mass shootings these drills are designed to prepare them for.
