Usage Note: The use of the participle credentialed to refer to certified teachers and other professionals is well established (She became credentialed through a graduate program at a local college), but its more general use to mean "possessing professional or expert credentials" is still widely considered jargon. The sentence The board heard testimony from a number of credentialed witnesses was unacceptable to 85 percent of the Usage Panel.
