Category talk:Public education in New York City

Drawing the line
I am confused by the distinction between this category and its child Category:New York City Department of Education. Many articles are in both, which by conventional usage is wrong, and for the ones that are in only one cat I don't see the reasoning behind which ones are in which. Is one of these categories just plain redundant and should be eliminated? Jim.henderson (talk) 02:40, 17 February 2010 (UTC)
