Continuing professional development (CPD) or Continuing professional education (CPE) is the means by which people maintain their knowledge and skills related to their professional lives.

CPD obligations are common to most professions. Many professions define CPD as a structured approach to learning to help ensure competence to practice, taking in knowledge, skills and practical experience. CPD can involve any relevant learning activity, whether formal and structured or informal and self-directed.

There is much research on the use of CPD in different domains. In an article by Mac Van der Merwe and Alta van der Merwe (2008) the authors focus on the personal and situational tensions impacting on the use of a mathematics-friendly interactive online discussion forum environment as a reflective tool for the CPD of advantaged and disadvantaged mathematics teachers in South Africa.[1]
