quality this, quality that

Do you ever think you know a word, only to be told that a way you've been using it all your life is incorrect?  But then you look it up in the Oxford English Dictionary and think that perhaps you really have been using the word correctly?  I'm speaking of "quality".  More specifically, the phrase "quality education". Or even more specifically,  "to assure a quality education for all students.."  I waded through 13, count them 13, senses of the word "quality" in the OED, and as close as I can tell, "quality education" is perfectly acceptable use of the term (according to a combo of sense 8 and 13).  But not according to a few people around here.   Whom do I believe, my own interpretation of the OED, or some other faculty? Hmm...
