In-service education is a structured program aimed at enhancing the skills and knowledge of employees, particularly nurses, while they are employed, focusing on professional growth and improved patient care. It encompasses orientation, skill training, leadership development, and continuing education, with the goal of keeping nursing personnel updated on the latest practices and nurturing leadership skills. Effective in-service education programs involve needs assessment, clear objectives, resource selection, budget establishment, and thorough evaluation to measure outcomes and future development.
