Managing your competencies has been revised on the basis of the authors' experiences and reactions of users of earlier editions.

What is a competency? A competency is a combination of knowledge, skills and attitude that you need to function well in specific professional situations. For example, a nurse must be able to inoculate a crying child. A nurse who cannot perform this task is regarded as incompetent - unfit to be a nurse. Likewise, a police officer must be able to pacify drunken pub visitors who have got into a quarrel. The profession one has or wishes to have will require certain competencies, and they may be specific to that particular job.

Why competencies? In higher education, competency-oriented teaching has become an important objective. If you as a student know what competencies you already mastered and can identify those that you will need for your future profession, you will be able to set up a so-called personal development plan (PDP) aimed at acquiring the ones you still need. You can do so relatively independently, by means of doing assignments and exercises. The crucial thing is making hour own PDP: you and you alone are that PDP's owner.
