That sounds simple but first you have to define what you mean by "neglect" and then, you are allowing the government to intrude on family affairs to an unprecedented degree.
What do you do if you have a single mother working a series of low wage jobs where missing work might mean losing your job? You going to put her in jail because she can't attend PTA meetings?
I see your point - but no way it can be done forcefully.
The only way it is done at all is in private schools by making it a REQUIREMENT of acceptance. In other words, the school has choice as to who they will accept.
I do believe in school choice in the public school sector...the schools should be able to choose what students they will accept, just like private schools already do.
I jest about jail, although the THREAT or the SHAME of going to jail esp. in cases of truancy, might add a little incentive to get Johnny on the bus in the morning.
I don't know about other states, but NJ has outlawed expulsion. We are required by law to educate every child until the age of 19; 21 if they are classified. Rapists, drug dealers, arsonists, etc. are entitled to a free and appropriate education. The kids know this. The parents know this. So hands are tied. The charter schools (and private schools) can dump every troublemaker they have on the public school and the public school has no where to dump them except maybe jail. They need the parents help. And if that requires a kick in the ass, so be it. But it would be best to start when they are young.
At my kids school, parents must pick up the report card at conferences. No mailing. Not a bad idea in my opinion.
