... Standards are minimums, not maximums, in every case
Some may say that in several professional disciplines, there are specified quality control tolerances for an item being +/- the "standard".

Different words and phrases can mean very different things to various individuals depending upon their knowledge base and lived experience. Whereas the Common Core standards do not seem to articulate plainly that they are a floor or minimum, for which there is no suggested corresponding maximum, many do not assume that to be the case. To alleviate any concerns, CCSS could simply add a sentence or two to clarify. Although this has been mentioned over time, they have failed to do so. To some minds, this speaks volumes.
