Because I have only five minutes, I'll jump over to what we were talking about, the proficiency levels. Any kind of grading system is a subjective thing, from elementary school right through to job applications.
My concern about adding a very specific measure in the law is that it will not account for any progress that may be made in the future in terms of language proficiency, skills, and expectations. As the country becomes more and more bilingual, one would hope and expect there would be a higher level of expectation of language proficiency—oral, written, comprehension, interpretation, and there might be something else added.
My fear in adding a limit is that the limit very quickly becomes a lower limit for what is available out there.
