In the field I work in I read a lot standards, have contributed to a couple, very minor changes though. A standard how I perceive it and I think many others is a number of clearly defined conditions that something must meet to be compliant with the standards. Something can usually fulfill more than what is prescribed in the standard, that is going beyond the standard while still complying with it. I haven’t read Common Core, you’re right on that, but I can read a summary of what is taught in different topics to comply with it, and those things I was taught long before graduating.

AP and IB cover standards more deeply, but the standards are the same.

And this is where I disagree, looking at summaries of what is prescribed in common core, much of what I was taught is never mentioned. Of course it’s not precluded, but an elementary school math standard doesn’t preclude teaching calculus- but calculus is beyond the standard.

Also I’ve never insulted you.

An insult doesn’t need to be, “you’re dumb”. Think about it like this, if you were telling your friend a story about how you personally witnessed someone do something ridiculous and you’re friend insisted that no one would do that so you are clearly wrong- would you feel insulted?
