That is the logic of a standards-driven system. Age and time in the saddle is no longer relevant. Social promotion must end. Routine and mindless teacher and administrator evaluations must be replaced with finely calibrated procedures that enjoy the confidence of educators and the community. Articulation between high school and life after high school must be rationalized and streamlined.
Talk is cheap.
It is easy to spin out a scenario of school reform and improvement on paper, but hard to execute in practice. For the initiator has the enmity of all who would profit by the preservation of the old institution and merely lukewarm defenders in those who would gain by the new one. For this reason it is nearly impossible for lasting reform to appear spontaneously, from within the institution itself. Outside stimulus is necessary. They change because they feel the heat.
