NFHS wrote their own rulebook next. In this, as well as similar categories, NFHS wanted to allow for unintentional mistakes, as the players are all youths, and the coaches are often less informed than coaches participating in ASA Championships, may have fewer assistants to help, etc. So, they set a warning in place for the first offense; if it happens again, it is then less an accident, and the more severe penalty applies, restricting the sub. Further, since NFHS does hold coaches accountable for their team, the coach is retricted, too.

High schools also have the added burden of insuring there is always a school "coach/employee" in attendence. Toss the coaches and the game is over.
