The wife of one of my good friends was on the county school board for 12 years. According to her, it was an unspoken secret was that parental involvement was the biggest predictor of / contributor to student success. The reason it was taboo was because you absolutely cannot expect anything from the parents. It was political suicide.
I would put dollars on the table that such is already happening for every parent that is willing and able to do it, because they were already doing it before too.
