Abstract: A study to determine the content validity of an education instrument to assess the clinical competence of Comprehensive Nursing Students and the reliability of the Nursing Teachers using the evaluation instrument to assess student Nurses performance depicted on videotapes of simulated clinical situations. 24 of the Nursing Teachers in a school of Nursing rated student Nurses clinical performance in simulated videotaped clinical settings. One half of these Teachers assessed the students without a specific evaluation instrument and their assessments were compared with the Teachers using the existing evaluation for assessing Nursing students' clinical competence. The evaluation instrument was judged to be valid in terms of content by the Nursing Teachers taking part in the study. Rated reliability of observer agreement was not demonstrated with 24 Nursing Teachers rating 3 Nursing Students' clinical performance as videotaped in simulated clinical settings. The usefulness of videotapes for determining observer agreement and as a tool for use in staff training workshops, in relation to assessing clinical competence of Nursing Students is established
