Hi, I emailed excelsior a few days ago asking this question this is what they responded with:
The Clinical Performance in Nursing Exam sites are as follows:
Albany, Schenectady, Utica, Queens and Syracuse, New York
Plano, Lubbock and Amarillo, Texas
Atlanta, Lawrenceville, Riverdale and Savannah, Georgia
Madison, Janesville, Milwaukee and Racine, Wisconsin
Chambersburg and York, Pennsylvania
I've heard its simulation to ensure you can properly do the tasks but I've also read that some people had real pt's. Hope the locations help.
