To run a school system?? Have you been following the Michael Bloomberg/Cathleen Black/David Steiner saga in New York City? Bloomberg wants a long-time media exec with no public educational experience and no apparent interest to “manage” (read slash costs) in the city schools. State educational commissioner David Steiner initially refused to grant Black an exemption from required credentialing – with apparent good reason – and Bloomberg, to his surprise, couldn’t garner enough political support to pressure Steiner. So the accommodation is a “chief pedagogical officer” to support (challenge?) Black’s lack of understanding.
