Purpose: This study examined the effects of a clinical nurse education program led by clinical nurse educators on nursing performance and education satisfaction for newly graduated nurses. Methods: This study used a non-equivalent control group pre-test_post-test design. The clinical nurse education program was conducted for the experimental group. The experimental and control groups were measured using self-reported questionnaires as pre and post-surveys. The preliminary homogeneity test of general characteristics and dependent variables between the experimental group and the control group was analyzed using a χ² test, Fisher's exact test, independent t-test, Mann-Whitney U test and ANCOVA. Results: The experimental group showed higher nursing performance than the control group (F=4.50, p=.039). The experimental group showed higher educational satisfaction than the control group (F=4.91, p=.031). Conclusion: The clinical nurse education program led by clinical nurse educators improved the nursing performance of new nurses and increased the education satisfaction.
