Background: Technology growth and development in medical sciences on cardio-pulmonary resuscitation (CPR), staff development in nursing and educational nurses' needs in emergency department is necessary. Aim: Assessing the effects of continuing education competency-based program for emergency nurses on rate CPR successful was the aim of this study.

Aim: Assessing the effects of continuing education competency-based program for emergency nurses on rate CPR successful was the aim of this study.

Methods& materials:  This semi-experimental study was carried out on (30) nurses (15 nurses in each groups control and case) who selected non- randomly in emergency departments in two hospitals in  Golestan University of Medical Sciences in 2011 .Data gathered were observational form, record, and report nurses' sheet for CPR. Their reliabilities were (0.89) by inter-rater coefficient. Continuing education competency-based program in regarding adult learning principles and steps of competency training  (CBT) planned and implemented in case group for six months Data were gathered before and six months after implementation in two groups in double blind. Data were analyzed by SPSS16 and Wilcoxon, Mann-Whitney and Chi-square statistical tests.
 
Results: findings showed that two groups were same in demographic variables and no differences significantly Chi-square test showed with (p>0.05).  Mann-Whitney test was revealed that between two groups, rate successful cardio-pulmonary resuscitation were different significantly (p<0.05). Also, Wilcoxon test was revealed that between rate successful cardio-pulmonary resuscitation before and after continuing education competency-based program found to be different between two groups (p<0.05).

Conclusion: it is suggested to nurse managers that continuing education competency-based program applied in staff development in emergency department for promotion rate of CPR.
