So Arizona education officials want to reassign teachers with heavy accents so that they aren't teaching students who are learning English.  The story's here and the first comment on the story is this:

Have you spoken with any college aged students lately? The number of functional illiterates in our primary and secondary school system is disheartening. Unless these students can hear English spoken correctly at home and on the street, yet alone taught it correctly in our schools we should all start calling it "bassetball" or say "ax" instead of ask, or perhaps we can all "boat" instead of "vote"??? how much further down do we have to lower our standards to allow for "the acceptable " lever of mediocrity?

"Lever of mediocrity?" "Yet alone?" 

Pot, meet kettle.
