Earlier quoted context omitted.
Ridiculous amounts of standardized testing and curriculums designed to optimize for that was the main thing we hated. Seems to be a thing everywhere. When I was a kid teachers had a bit more freedom to decide what to teach but now you teach to the test or lose your funding.
Teachers absolutely should teach to the test. And individual teachers really shouldn't be in the business of deciding what to teach, either. Why is there an assumption that what is on the test is inherently worthless but every individual teacher is qualified to design an entire curriculum?
Because my mother went to school for six years for exactly that purpose? Some states have pretty high requirements for teachers, and they tend to do well.
Also, the "teach to test" BS is extremely locality dependent. There are zero things you can generalize across all public schools in the US.
