The pilot study to demonstrate the utility of the CBRDM in the practice setting was successful. Using a matrix evaluation tool based on the model's competencies, evaluators were able to observe specific performance behaviors of senior nursing students and new graduates at either the novice or competent levels. The study faced the usual perils of pilot studies, including small sample size, a limited number of items from the total CBRDM, restricted financial resources, inexperienced researchers, unexpected barriers, and untested evaluation tools. It was understood from the beginning of the study that the research would be based on a program evaluation model, analyzing both processes and outcomes. However, the meager data findings led to the desire to continue to study use of the model for practice setting job expectations, career planning for nurses, and curriculum development for educators. Although the California Strategic Planning Committee for Nursing no longer has funding, we hope that others interested in role differentiation issues will take the results of this study and test the model in other practice settings. Its ability to measure higher levels of competency as well as novice and competent should be studied, i.e., proficient, expert, and advanced practice. The CBRDM may be useful in evaluating student and nurse performance, defining role expectations, and identifying the preparation necessary for the roles. The initial findings related to the two functions as leader and teacher in the care provider and care coordinator roles led to much discussion about helping students and nurses develop competence. Additional discussion focused on the roles as they apply to settings such as critical care or primary health care. The model is useful for all of nursing as it continues to define its levels of practice and their relationship to on-the-job performance, curriculum development, and career planning.
