The authors discuss a study that examined the relationship of prenursing admission variables to success on the National Council Licensure Examination-Registered Nurse (NCLEX-RN). The sample included 325 associate degree graduates from 1997-2001. Statistical analyses revealed that grade point average at admission is the strongest predictor of success. Course grades on psychology and natural sciences are also positively related to success. The results will help nurse educators to select applicants with greatest potential for success and identify "at risk" students early.
