There’s many mechanisms by which a school can be influenced and covering them all at a high level is difficult. In trying to set specific process controls, you merely encourage gamesmanship: “this wasn’t done by the board — we voted to outsource our decision to a NGO!”

A more effective mechanism is to define the standard (ie, don’t talk to kids below 9 about sex in schools) — but give enforcement powers when that standard is breached to the people actually impacted by that breach. This law gives people a tool to hold government accountable when it breaches the norms expected by the community, eg when they groom children.
