This report addresses the unstable and unsatisfactory performance of Chicago, Illinois' Olive-Harvey College's (OHC) associate degree nursing (ADN) graduates on the National Council Licensure Examination for Registered Nurses (NCLEX-RN). An ex post facto correlation study was designed to determine the worthiness of pre-nursing admission course grades, test scores, support course grades, nursing course grades, and the number of repeated nursing courses as predictive variables for NCLEX-RN performance. Study results revealed that there were significant correlations between the grades in several nursing courses; the score on the OHC comprehensive examination; and number of repeated nursing courses and the NCLEX-RN score. It was determined that nursing students who were experiencing difficulties in passing nursing courses at both levels of the nursing program were likely to fail the NCLEX-RN. Suggestions included: (1) that programs and services such as counseling, individualized academic assistance, and NCLEX review be offered to help the individual student better prepare for the NCLEX-RN examination; and (2) that faculty should reevaluate the program's pre-nursing and support course requirements and be given administrative support in implementing changes. The appendix contains the program guide for the Olive-Harvey College Department of Nursing. Contains 15 references. (GLR)
