The Delphi technique is a useful method of obtaining group consensus. However, "consensus" is not usually defined when this technique is used. This paper describes a study in which two panels of experts (registered nurses who were nurse managers or involved in management education) were asked to identify the competencies expected of first-line nurse managers using the Delphi technique. The results from both panels are compared. Prior to the commencement of the Delphi rounds a baseline mean of 3.00 ("agree" on the Likert scale used) was set for the inclusion of items. The level at which consensus was achieved was defined as the point at which 10% or less of the 168 competencies provided to the panel moved above or below this point of inclusion. A total of 156 of the 168 competencies (93%) presented to the two panels were either retained or rejected by both.
