Also, if they were so worried about test questions becoming "unusable" in the future, they should have thought about what would happen when the news media reported on their mistakes.
It all adds up to a disturbing wall that keeps parents out of their own children’s lives. It’s a whole culture rather than just a one off thing about this incident or others.
Also, while they may lack a teacher's credential, they may have other (and in many cases, at least around here) more rigorous advanced degrees. It is fairly well-known that education majors enter college with the lowest average SAT scores and exit with the highest GPAs.
Parents who are volunteering in the classroom are not there "to audit" the teacher's performance. They are there to help. If they notice the teacher is incompetent, they would be crazy to ignore that fact.
I have seen so many ELA handouts with typos come home with my kid. And a teacher recently multiplied 5 x 7 in class and got 30. If my basic skills were this bad, I wouldn't want anyone but children (who might not know the difference) around to judge me.
The school also erred in taking an adversarial tone over the photos the family took.
