And many -- perhaps most -- high school teachers have a similar "white list based" policy because they're unable or unwilling to a) admit that any graphing calculator makes cheating basically impossible to prevent without extremely careful proctoring; and/or b) emphasize learning even at the expense of weakening the signaling value of credentials. IMO tests should be designed sot that calculators aren't necessary. I can't ever remember using a calculator in university, and that's really the only place I actually learned any mathematics in a classroom setting.
