Developments in crew resource management (CRM) have progressed from the int
roduction of training programs to the evaluation of CRM skills, particularl
y for multicrew cockpits. European regulators responsible for flight operat
ions and flight crew licensing (Joint Aviation Authorities, 1996, 1997) are
introducing requirements for the training and assessment of pilots' nontec
hnical skills. This article reports a review of the literature and a survey
of current practice in the development and use of behavioral marker system
s for training and assessing nontechnical CRM skills in international and d
omestic (UK) airlines. In general, there appears to be a wide range of prac
tice in the design and implementation of behavioral. markers systems within
CRM programs. Emerging issues relating to content validity of marker syste
ms and rater reliability are likely to become the focus of both researchers
' and pilots' interest.
