It's understood that education is primarily directed toward kids. That's where the money is in publishing.
Certainly, all ages are in school, but generally, 6 to 22-year-olds are the market. Content is created with that age group in mind: from first grade through the fourth year of college.
Sometimes the content given to teachers is not far enough Left, so they supplement other materials, with approval, of course.
This is what happened in an elite private school.
Be informed, not misled.
