Out of curiosity, when you've fired all of these teachers, who replaces them? There aren't legions of teachers to replace them just waiting in the wings, who have a magic wand and turn students around who have failed to perform because of a lazy teacher.

Also, who then would want to work with students with disabilities, English language learners, and schools with a high level of poverty that continually do poorly on testing? Why would any teacher want to subject themselves to that risk of being fired when they inevitably "fail" to meet the standard you've created?

Let's fire a doctor when they have a patient gets sick or dies, and fire lawyers when they lose a case. To hell with the context and other circumstances, or even personal responsibility of students and parents, let's fire everyone! We can raise your taxes to help pay for their welfare since they won't  have jobs any longer.
