Why not instead celebrate the teachers who do pass and offer remedial instruction for those that don’t. Send them back to school to learn, not into the classroom to teach. Stupid to lower standards to meet some diversity goal. Students lose. ...and that is color blind and without regard to ethnicity.
Why should taxpayers have to pay for remedial education for stupid people? Just cull them from the herd and move on. Nationwide, there is a surplus of teachers as it is.
With school choice coming up, there will be even less need for state indoctrination centers.
