There are several sources on "international benchmarking" of standards, which are all exclusively about math and science, not English. There is, however, a whole section on "Disciplinary Literacy Research," from which these standards are clearly drawn.
The question, then, is whether we want to narrow our standards from "English Language Arts" to merely "disciplinary literacy." From what I've gathered so far, no other country finds this sufficient. The idea that this represents raising standards to meet international norms is an utter joke.
