Actually, you can. I know of 2 guys who changed schools after they got D.

Two different outcomes though:

One was given a lecture by his new school’s principal on his first day at the new school and was told that teachers who get D would continue to get D in the new school. The next 3 years was hell for him. He was treated badly in school and given D every year after that. In the third year that he got D, the principal even told him that they would observe his lesson every week and were considering giving him an E. He quit.

The next guy had a new lease of life in his new school. He excelled and got A for his appraisal.

So everything depends on the SLs. If they want to give you hell, there’s no way you can get out of it.
