I work as academic coach with students across the country, so I see the curriculum state to state.
While I don’t work w/ K-6, from what I see the indoctrination is most extreme in middle schools, where, it seems teachers are most free to wander off established curricula and bend young minds.
High school teachers tend to mix leftism into their lessons, but the high school curriculum is actually very defined, and, believe it or not, standards keep teachers in line. Schools w/ AP are the least susceptible to the progressive drift. I’ve got a couple kids in the most competitive of San Jose public schools, and while I see politics now and then, it’s mostly about the three RRRs, only straight As, 5s on the AP and 1600s on the SAT or die.
DC, btw, is the worst for progressive b.s., especially in its pasty-white N.W. quarter.

I am a college educator, but also sit on my local School Board as an elected official.
School Board members are not allowed to directly interact with classroom instructors and employees. We must work "through" the Superintendent's office, to gather detailed information.
We are allowed to see aggregate numbers, such as SAT scores, spending per pupil, and so forth. But what is taught on a daily basis in each classroom is not easily accessible. It is not easy to get information on Grade level lesson plans and subject coverage (though I am trying to change that).
In short - if we do not hear from parents - we do not hear much. Parents are the eyes and ears for the School Board. They MUST speak up, either to the Superintendent or directly contact their elected School Board officials, if they see something sketchy in the curriculum that is unacceptable, biased, unethical, etc. Then we contact the Superintendent, and begin a review "process."
