Random Thought

Random thought of the day: last year, NYC implemented a new policy that requires every restaurant to display prominently in the front window the letter grade it receives on its sanitary inspection, based on unannounced visits (see: www.nyc.gov/html/doh/html/rii/index.shtml and www.huffingtonpost.com/2011/02/09/nyc-restaurant-grades_n_820918.html).  Why isn't school in America evaluated and the grade posted on the wall outside the front door???
