Abstract
Staff development educators use many sources of information to conduct educational needs assessments to improve existing educational programs and to develop new ones. Staffing effectiveness evaluation information targets patient care and staffing outcomes. The overall objective of this article is to familiarize staff development educators with the staffing effectiveness evaluation process, events that have led to organizational efforts to measure it, Joint Commission on Accreditation of Healthcare Organizations' (JCAHO) expectations, methods for assessing variation and relationships of indicators, and implications for staff development educators.
