An interesting New York Times article on the challenges in rating and evaluating teacher effectiveness.  Evaluating teacher performance to provide greater accountability and to retain the most effective teachers has been a major push of late by the Gates Foundation, the Race to the Top, and experimental policies in many public school districts.

Though few if any Catholic school systems are using similar teacher ranking systems, this may be the way of the future for measuring and ensuring academic quality for schools in the U.S.  It is worth staying up to speed on the challenges and innovations in this policy area.
