Abstract: A maternity nursing staff that performs according to global occupational and professional standards can offer safe care service for women and newborn. This study aimed at identifying the effectiveness of an intervention technique to increase awareness of the maternity competency standards among intern students. A quasi-experimental research design was utilized (time-series one group). A purposive sample of 70 female intern students in the Faculty of Nursing at El-Minia University participated in this study. Data were collected through three tools (1) Personal Data Sheet, (2) Maternity Competency Standards Checklist (MCSC); this is a structured or closed questionnaire and (3) Knowledge Test. Procedures included  a pretest wherein the MCSC and the Knowledge Test were administered to the sample of the study, followed by an intervention for 12 weeks, posttest occurred 1 immediately after the intervention, and posttest 2 occurred one month after posttest 1. The study revealed that there were significant differences in students' overall competence (p < 0.05) between the pretest and the posttest1. There were non-significant differences in students' overall competence (p > 0.05) between postest1 and posttest 2 nor between posttest 1 and posttest 3 (p > 0.05). It was concluded that using an intervention technique increased awareness of the maternity competency standards among intern students and thus the conclusion of the research findings supported the research hypotheses. The researcher recommended that maternal competency standards should be part of the academic and professional preparation of intern students and the evaluation plan at the Faculty of Nursing.
