Granted, a supervisory staff does evaluate the principals after they are in the position. The principals evaluate teachers after they are in the position. By that time the person already has the position and it is more difficult to remove them after they already have the job.

The job of distinguishing good from poor educational personnel should have been done way before they were given the job. Otherwise administrators will face justificable blame them for weak performance.

In many cases teachers fail because of a mismatch. A good administrator would have prevented this problem from occurring in the first place.

Imagine the feelings of the teacher who is required to move like a pawn to a different position. She will feel justifiably wronged by the incompetent placement officer. Should she now start her new job with frustrating uncertainty, knowing that she may be moved again because of an unfair placement, whereas the placement officer himself will remain in the position to mislead others?
