For those who teach digital skills, having strong digital application abilities is crucial. Additionally, the usage of simulation programs is expanding in higher education institutions because of the COVID-19 epidemic. This raised new issues on how to investigate the effects on the growth of instructors of digital abilities in the simulation program. The purpose of this study is to investigate how simulation programs can help teachers of digital skills improve their knowledge of digital applications. Affiliates of the Optimum Investment Program made up the participants, who were split into the experimental and control groups. The experimental group use simulation software to study the "Digital Applications" course. The typical classroom teaching method is used to instruct the control group. A digital application skills observation card was employed as a study instrument to help achieve the study's goal. In comparison to the conventional approach, the findings demonstrated the efficiency of simulation programs in honing the digital application skills of Najran's teachers of digital skills. The outcomes offer crucial proof of the benefits of simulation programs in the research and advancement of the educational profession
