Background:Nurses give care to diverse client population, which necessitates that, they should be culturally competent. Competence in cross cultural practice is a process requiring experience and continued interest in learning and in sharpening cultural assessment and communication skills. Objectives: Toinvestigate the cognitive competency of Filipino nurses working in five hospitals at Taif City, Kingdom of Saudi Arabia. The study evaluates strength of self-efficacy perception ofthenurses, on the cognitive constructs and the difference among the strength of self-efficacy perception of the nurses when grouped according to their demographic profiles. Methods:Transcultural Self-Efficacy Tool (TSET) Kit was used to measure the cognitive competency of three hundred and seven respondent Filipino nurses working in five hospitals of TaifCity. Results:The strength of self -efficacy perceptions of the nurses within the cognitive constructs shows  that the five  highest means score dealt with “safety", “hygiene", “Informed consent", “pain relief and comfort" and “life support and resuscitation" while the five lowest scores dealt with “Health History and Interview", “Sexuality", “Birth", “Pregnancy" and "Diagnostic Test". The differences among the strength of self -efficacy perception of the nurses on the cognitive construct when grouped according to seven demographic profiles shows that only three of the demographics were different in some of the cognitive construct variables. These were work setting, department and preferred position Implications:The findings of the present study suggest in-service educational training to all nurses on transcultural nursing to enhance their cultural competencies.In addition, Arabic Language training is recommended as one of the requirements for new nurse applicants.
