It is important for nurses to consistently enhance their knowledge and abilities, which can be achieved through participating in Continuing Professional Development (CPD) programs. The objective of this research is to implement a CPD program at PHCCs that will maintain the standard of nursing services. This will be accomplished through a training needs evaluation that was conducted in 2021. Methods: The research conducted was a secondary quantitative study known as a "desk study". The data used for this study was collected in 2021 from Primary Health Care Centers (PHCCs) in Riyadh, Kingdom of Saudi Arabia, specifically from the Riyadh First Health Cluster. The participants were recruited from these health centers and were all nurses. The study interviewed a convenient sample of 700 nurses and managed to get a response rate of 82.4%. Results: According to the study, a significant number of nurses (84.8%) held a Diploma of Science in Nursing, indicating that the study participants recognized the advantages of attending continuing nursing education. The nursing staff prioritized learning essential concepts and principles for performing nursing procedures and improving their advanced nursing skills. Although the majority of the sample had a Diploma degree, most of the respondents expressed a desire for professional development in leadership and management knowledge and skills. Conclusion: It is important to establish a continuing education program that is tailored to meet the professional requirements of nurses working in primary health care centers. The design of such a program should consider the challenges that inhibit nurses' participation in continuing professional development (CPD) and develop effective strategies and frameworks to enhance their involvement in community health.
