It is an HS rule and I believe it works this way in NCAA -as afar as I know, self pass is an NBA rule only. In HS rules, once a shot is attempted, anybody, including the shooter, can rebound it regardless of whether or not it touches anything. The key is whether or not the official judges it to be an attempt.
Of course, in pick-up, you have no official, so you get a split ballot on this issue of shot or self-pass. We always played in pick-up that you had to hit something because it saved arguments, not because it was a HS rule. It works better that way. And it evens out, unless you happen to do this more than most players, in which case I advise you to work on your shot, and not this rules interpretation
