Definition of a shot from behind the backboard- High School

[Nevadaref]

The US high school rules, NFHS, are the same for correctable error, aussie, except that we also have a fifth: shooting the FTs at the wrong basket.
Also you should know that not all correctable errors happen during a dead ball. Erroneously counting or canceling a score may happen during a live ball. Think of judging whether a shot is worth 2 or 3.
The NFHS case book specifically points this one out as a correctable error if it was observed by an official.
