What refers to on-the-job education, which may include workshops and seminars?

The correct answer is professional development. This term encompasses a broad range of educational activities, including workshops, seminars, conferences, and other training opportunities that help individuals improve their skills and knowledge in their professional field. Professional development not only focuses on enhancing one's current skill set but also prepares individuals for future roles, responsibilities, and challenges within their careers.

Unlike training, which typically refers to a specific set of skills or knowledge that one is learning for a defined purpose, professional development takes a more holistic approach to growth, encompassing ongoing learning opportunities that support personal and professional advancement over time. It also differs from continuing education, which is more formally structured or related to ongoing academic credit. Skill enhancement is often a component of both training and professional development but lacks the broader scope of lifelong learning and career progression associated with professional development.
