Assessing comprehensive nursing performance: the Objective Structural Clinical Assessment (OSCA). Part 1--Development of the assessment strategy.

Nursing courses in Australia are preparing graduates for comprehensive practice within Universities. The evaluation of safe and effective comprehensive nursing performance requires the consideration of a much broader range of practice competencies than has previously been the case. In particular there is a need to explore integrated assessment approaches that closely resemble the realities of the health care setting. Part 1 of this paper provides an overview of the Objective Structured Clinical Assessment (OSCA) which it is suggested is an effective way of assessing student comprehensive nursing performance. Some theoretical considerations in OSCA development are discussed and then an outline of the processes involved in designing and implementing an OSCA provided. Part 2 describes an evaluation project supported by the NSW Nurses' Registration Board. The aim of the study was to determine the validity and reliability of the use of the OSCA as an integrated assessment tool as a measurement of the extent to which a student nurse can plan and deliver safe and effective comprehensive nursing care.

Assessing comprehensive nursing performance: the objective structured clinical assessment (OSCA). Part 2--Report of the evaluation project.

Part 1 of this paper described the development of an assessment strategy used to measure the clinical performance of student nurses undertaking preparation for practice within the tertiary education sector. The challenge of developing an appropriate technique in assessment to accommodate a comprehensive nursing register was described. Features of the design and implementation were also provided. Part 2 describes an evaluation project developed by the staff and supported by a research grant from the New South Wales (NSW) Nurses Registration Board. The aim of the study was to determine the validity and reliability of the Objective Structured Clinical Assessment (OSCA) technique. The research design incorporated the use of triangulated data: student questionnaires, judgments made by a panel of experts and an analysis of the statistical correlation between the students' results in the OSCA and results in other areas of assessment.
