The way this article puts it, it's that only roughly a quarter of kids reached "proficient."
There's a difference between "proficient" and "excellent," I think, or at least an implied distinction.
After all, you can be proficient in French without being the next Jean-Paul Sartre...the next Sartre would be "excellent," having a grasp of most of the language and words to a pretty good and workable degree would be "proficient," and then "basic"--what it says 54% or so of students tested into--would seem to be analogous to having a high school French I understanding of the language--
Namely, sure, you might know a few scattered sayings, and the structure, but try to communicate in any meaningful or (more importantly) business-savvy way with it, and you'll run into problems, as to succeed in business linguistically, undeniably, one must be proficient AT LEAST--
You can't very well just have a very, very basic understanding of the language of business and expect to pull of complex trade negotiations, after all.
A lucky few MAY squeak by, but not the majority.
