I thought the article was terribly biased against public schools. The author takes the experiences that of one district and extrapolates it to the whole.
Just because kindergartners are taught about intercourse in one district in NY or in CA (and who knows what goes in San Francisco) doesn’t mean it happens in every public school in the country.
There is value in the article in that it reminds parents to review materials and make sure they are in line with the student’s personal beliefs - but largely it is nothing more than a scare tactic.
The biggest surprise I had when we started homeschooling was the number of ex-teachers that home school their kids.
You can really never make generalizations, however the public school system is broke. As a whole the standards are the decline as are the graduation rates. Sure there are examples of good schools but the NEA will probably fix those soon.
Note I didn’t say the teachers are the problem, by and large they are not. Its the bureaucracy and the union that is the problem.
