Criterion-referenced competency assessment and the national certification examination in nurse-midwifery

The paper presents an overview of the recent change from norm-referenced to criterion-referenced score interpretation for the ACNM certification examination for entry level practice in nurse-midwifery. The advantages of criterion-referenced interpretation are presented. A successful adaptation of the Nedelsky method for the calculation of the minimum pass index, based on the identification of acceptable error, is discussed. Implications for the nurse-midwifery profession and for the national certification examination in nurse-midwifery are considered.
