<p>You’re absolutely correct. I was simply pointing out that your list, before you inserted “etc”, was limited to grammar examples and excluded other critical elements of writing proficiency.</p>
<p>I’m not sure if any “set of standards” exist that separate good writing from great (I’m sure many would argue that point). But I still disagree with your assertion “that ‘mastery’ doesn’t have a lot of meaning in the humanities and social science context at a good high school (or good middle school, for that matter).” My experience is that in discussions of K-12 education, “mastery” is usually defined as “full command or understanding of a subject commensurate with grade level standards”.</p>
