Isn't it interesting, that after many principals in many locations have shown themselves to be limited-thinkers, lacking vision, and out-of-touch with today's classrooms --  there are still some who would give them even more authority than they already have? (second to the district, perhaps, but above the trained and experienced teaching staff.) One columnist has suggested that schools follow the business and medical model -- where an "administrator" is just that, and the doctors (or other workers) do the job they are trained for without judgement from one trained and experienced in a different and conflicting mode (that of PR, bottom line, and group-think)? As it is, a great teacher can easily be defamed  and black-listed by the evaluation of an administrator with an agenda.  Thnk of Thoreau marching to the beat of a different drummer, Ghandi overthrowing colonialism, or Sojourner "Ain't I a Woman?" Truth, all of whom challenged the status quo. Today, they'd probably be unemployed. Labelled "not team players," I guess.
