The Academic Progress Rate is a hammer the NCAA has used to ban schools from Post Season competition. UCONN for example was banned from the 2013 NCAA tourney and penalized 2 scholarships.
APR is a joke. UConn has to be a complete failure to be penalized. In order to be in "good standing" a player only has to be passing his classes. It only takes 50% in good standing to not be in violation. The last three players on an NCAA basketball bench came in as top scholarship, top academic students who are only on the team for practice and APR reasons.** Any player who leaves to turn pro or transfers in good academic standing does not count in APR. So it six player go pro or transfer you're left with nine players for the NCAA to evaluate for APR. You need five in good standing to be in compliance. Three of them are sitting in the end of the bench and not on scholarship. Therefore, two of six legit players have to be in good standing for the program to be ok. And UConn screwed this up.
